When an vertical layout is adopted for an unavoidable reason, install a partition plate or the like between inverters to isolate the heat of the lower inverter.
Remove the main circuit terminal block cover to connect the main circuit terminal block. Correctly connect cables taking care of the following precautions. If the power cables are connected to other terminals, the inverter will be broken. As well, check the source voltage for the allowable voltage range specified on the nameplate and so on. Check if the cables are connected correctly.
Check if there is no failure of connection. Check if terminals or cables are short circuited or there is a ground fault. Wait until the residual voltage is discharged before shorting a circuit, to avoid being hit by sparks caused by the voltage electric charge. Use when necessary. U,V,W Inverter output Connects a 3-phase induction motor.
G grounding Grounding terminal of the inverter chassis housing. Connect to the protective ground. Connect the main circuit power input terminals to the power supply through a circuit breaker for circuit wiring protection or an earth leakage breaker. There is not need to match the phase sequence. It is recommended to connect a magnetic contactor to disconnect the inverter from the power supply to prevent a failure or accident from becoming serious upon activation of the protective function of the inverter.
Do not turn the main circuit power supply on or off to start or stop the inverter. If it is unavoidable to turn the main circuit power supply on or off to start or stop the inverter, limit the frequency to once an hour or fewer. Do not connect to a single-phase power supply for 3-phase input inverter. Connect these terminals to a 3-phase motor with the correct phase sequence.
If the direction of rotation does not match the operation direction, change arbitrary two cables among the U, V and W phases. Do not connect a phase advance capacitor or surge absorber to the inverter output. If the wiring length between the inverter and the motor is extremely long, the stray capacity between cables causes a high frequency current, possibly tripping the inverter due to an overcurrent, increasing the leakage current, or deteriorating the current detection accuracy to cause deterioration of the performance or other phenomena.
To prevent such trouble, limit the wiring length of the motor to 50 m for 4. Note: When a thermal relay is installed in the path between the inverter and the motor, or especially in the case of a V system, the thermal relay may malfunction even with a wiring length shorter than 50 m.
In such a case, add an OFL filter or lower the Motor sound adjustment carrier frequency of the inverter. Function code F26 Motor sound adjustment. Use this terminal to connect a DC reactor option. Remove the jumper connected in the factory before connecting the DC reactor. Do not remove the jumper if no DC reactor is used. An external braking resistor option is necessary for frequent operation or heavy duty inertia load operation to enhance the braking performance.
Arrange devices so that the wiring length is within 5 m and twist or closely in parallel place the two cables. The metallic frame of electrical equipment must be grounded in accordance with national or local electric code to avoid electric shock, fire and other disasters. The method of connecting control function terminals varies according to the function setting.
Refer to the connection method for the function. POT: 1 to 5 kohm. X1 Digital input 1 X2 Digital input 2 X3 Digital input 3 X4 Digital input 4 X5 Digital input 5 A coast-to-stop command from an external device, external alarm, alarm reset, multi-step frequency selection and other functions can be assigned to the X1 through X5 terminals.
Refer to the terminal function E01 to 05 setting method in section Detail Description of Each Function. The signal description can be selected from the following. The signal description is the same as the FMA signal. Refer to terminal function E20 to 21 setting methods in section Detail Description of Each Function.
Isolated from terminals CM and If the P24 terminal is overloaded or connected with the CM terminal, the inverter trips with Er3 indication. To reset, remove external causes and, after several minutes, turn the inverter on again. Relay output 30A,30 B,30C Alarm relay output When the inverter is stopped with an alarm, a relay contact output 1C is issued. Contact capacity: 48 Vdc 0. Item min. Because weak analog signals are handled, these signals are especially susceptible to the external noise effects.
Route the wiring as short as possible within 20 m and use shielded cables. In principle, ground the shield of the shielded cable; if effects of external inductive noises are considerable, connection to terminal 11 may be effective. Use twin contacts relay for weak signals if relay is used in the circuit.
Do not add a contact to terminal When the inverter is connected with an external device outputting the analog signal, a malfunction may be caused by electric noise generated by the inverter according to some type of the circuit of the device.
If this happens, connect a ferrite core or capacitor to the device outputting the analog signal. To use contact input, use a reliable contact free from poor contact. Circuit configuration shown in Table for transistor output is adopted. Take care of the polarity of the external power supply. To connect a control relay, connect a surge absorbing diode across the coil of the relay. Route the wiring of the control terminals as far from the wiring of the main circuit as possible.
Otherwise electric noise may cause malfunctions. Fix the control cables inside the inverter to keep them away from the live parts of the main circuit such as the terminal block of the main circuit.
This is banned in the low voltage directive models for Europe. Electric shock could occur. Take care of malfunctions of the nearby sensors and devices. An accident could occur. For details of selection, refer to the concerning technical documents. Operation Inspection and Preparation Before Operation Check the following before starting operation.
Especially check if the power cables are connected to inverter output terminals U, V and W and that the grounding cable is grounded without fail. Check if the keypad panel shows an alarm.
Check if the fan built in the inverter rotates. Refer to chapter 4 "Keypad Panel" and chapter 5 "Selecting Functions" to select the method most suitable for the purpose and operation specification. Table shows general operation methods. In the factory shipment state, the inverter is in the keypad panel operation mode. To stop, press the STOP key. Check if the direction of rotation is correct. Check for smooth rotation without motor humming or excessive vibration. Check for smooth acceleration and deceleration.
When no abnormality is found, raise the operation frequency to check. After checking for correct operation during the above test operation, start normal operation. Caution 1: If any abnormality is found to the inverter or motor, immediately stop operation and determine the cause referring to chapter 7 Troubleshooting.
As well, the smoothing capacity is not discharged immediately after the power is turned off and it takes time for the capacitor to be discharged. To touch the electric circuit after turning the power off, check that the charge lamp is unlit and check for safe voltage using a multimeter. In the programming mode, use these keys to change the function code or data setting.

In the case of input with polarity, operation at a direction opposite to the operation command is possible. Refer to the description of the E01 to E05 functions for details. Normal mode operation Inverse mode operation Maximum frequency Normal mode operation Inverse mode operation Setting range: 50 to Hz If a value larger than the rating of the driven unit is set, the motor or machine may be broken.
Set a value suitable for the driven unit. F04 Base frequency 1 This is the maximum output frequency in the constant torque zone of motor 1, that is, the output frequency at the rated output voltage. Set the rating of the motor. Setting range: 25 to Hz Note If the setting of base frequency 1 is larger than the setting of maximum frequency 1, the output frequency is limited by the maximum frequency and the output voltage does not rise to the rated voltage.
F05 Rated voltage 1 This is the output voltage value at base frequency 1 which is output to motor 1. However, voltages exceeding the source input voltage cannot be output. Setting range: 0, 80 to V for V class 0, to V for V class A "0" setting stops the operation of the voltage adjustment function.
Therefore a voltage proportional to the source voltage is output. Note If the setting of rated voltage 1 is larger than the setting of maximum output voltage 1, the voltage is limited by the maximum output voltage and it does not rise to the rated voltage.
F06 Maximum voltage 1 This is the maximum value of the output voltage of the inverter of motor 1. Setting range: 0, 80 to V for V class 0, to V for V class F07 Acceleration time 1 F08 Deceleration time 1 These are the acceleration time taken for the output frequency to reach the maximum frequency from the start, and the deceleration time taken to stop from the maximum output frequency.
Setting range: Acceleration time 1: 0. Therefore the uppermost three digits can be set. The acceleration time and deceleration time are set based on the maximum frequency. When these functions are activated, the time becomes longer than the operation time explained above. The following options can be selected.
If operation continues in such a state, the motor may be overheated. Set a value according to the characteristics of the driven motor. F10 Electronic thermal overload relay 1 Select F11 Electronic thermal overload relay 1 Level F12 Electronic thermal overload relay 1 Thermal time constant The electronic thermal overload relay watches the output frequency, output current and operation time of the inverter to prevent the motor from overheat.
F10 Selection between active and inactive operation of the electronic thermal overload relay and selection of the target motor are made. When the general purpose motor is selected, the operation level is low at low revolution speeds according to the cooling characteristics of the motor. Setting: 0 Inactive 1 Active for general purpose motor 2 Active for forced-ventilated motor F11 The operation level of the electronic thermal overload relay is set in amperage.
Enter the value 1. Setting range: 0. Typical current - operation time characteristics 0 5 10 15 20 0 50 Operationtime min. You can select between protective operation alarm output, alarm display, and inverter output shutoff upon detection of power failure to be taken against an undervoltage and restart after momentary power failure where the coasting motor is not stopped but automatically restarted after the source voltage is recovered.
Setting range: 0 to 3 Refer to the table below for details of the function. Setting Name of function Operation upon power failure Operation upon power recovery 0 Inactive after momentary power failure The inverter trips immediately. Upon detection of an undervoltage, a protective function is activated to stop the output. The inverter does not restart. Upon detection of an undervoltage, no protective function is activated but the output is stopped.
A protective function is activated; the inverter does not restart. The inverter restarts after the protective function is reset and an operation command is input. The inverter automatically restarts at the output frequency effective at the time of power failure.
The inverter automatically restarts at the starting frequency set at F Function codes used for the restart after momentary power failure include H13 and H Refer to the description of these codes, too.
As well, a rotating motor pickup function can be selected as a starting method after a momentary power failure. Refer to function code H09 for details of setting. When the pickup function is used, the speed of the coasting motor is detected and the motor is started without a shock.
Because a speed detection time is necessary if the pickup function is made effective, the pickup function should be made ineffective and restart should be made at the frequency effective before the power failure in a system with a large inertia to restore the original frequency, to make the most of the small decrease in the speed of the coasting motor.
The effective range of the pickup function is 5 to Hz. If the detected speed is out of the effective range, the inverter restarts according to the regular function of restart after momentary power failure.
Priority is given to the High limit value. The operation is as shown in the figure below. However, if the bias frequency is larger smaller than the maximum frequency - maximum frequency , the limit is set at the maximum output frequency - maximum output frequency.
