6.7 Test Run with the motor
The following figure shows an example of basic connection is basic. Please refer to section 6.6 wiring for
operation command and frequency command from the control circuit terminal block. On how to operate the
parameter settings, please refer to section 6.5. To set the parameter, the operator is required.
No.
Procedure
1 Please check whether there is any problem with the wiring.
2 Turn on the power to the inverter.(POWER lamp(red) lights.)
In case of input operation command and frequency command without operator.( State initial shipment) *1)
3 Turns on both intelligent input terminal 3,4(CF1,CF2). (Multi-speed freq. 3 : The initial value is set 20Hz.)
4 Push RUN/STOP/RESET key. RUN lamp(while driving) is lit.
5
Please check and that there is no abnormality in the inverter and motor rotation direction motor rotation speed.
If the direction of rotation of the motor is different, please turn off the inverter and cheak Power lamp is
OFF.Please replace the two phases of the three-phase wiring of the output.
6
If there are no problems, only to turn on intelligent input terminal 3 (CF1). (Multi-speed freq. 3 : The initial value
is set 60Hz.)
7
After checking the operation, push RUN/STOP/RESET key. Motor starts to slow down. The RUN lump(while
driving) turns off when the motor is stopped.
In case of input operation command and frequency command from control circuit terminal block.
3
Check that the the input value is (zero) to O / OI of the frequency command.
The only one on the an intelligent input terminal 1(FW) or intelligent input terminal 2(RV). RUN lamp(while
driving) is lit.
4 Gradually increasing the analog voltage / current frequency command to O/OI.
5
Please check and that there is no abnormality in the inverter and motor rotation direction motor rotation speed.
If the direction of rotation of the motor is different, please turn off the inverter and cheak Power lamp is
OFF.Please replace the two phases of the three-phase wiring of the output.
6 If there are no problems, gradually increasing the analog voltage / current to O/OI.
7
After checking the operation, the only one off the an intelligent input terminal 1(FW) or intelligent input terminal
2(RV). The RUN lump(while driving) turns off when the motor is stopped.
In case of input operation command and frequency command from operator. *1)
3 Set to "operator" frequency source setting. (A001=02)
