Calibration - Mitsubishi Electric FR-V5AX Instruction Manual

THERMISTOR INTERFACE

5.5 Calibration

Calibrate the inverter and FR-V5AX (thermistor interface). Always calibrate them at the time of installation.
(1) Calibration method
1) Remove the jumper from the lower pin of CON2 and insert it into the upper pin to choose the ther-
mistor calibration status.
2) Read Pr. 925 and set a compensation value.
(For the setting method of the compensation value, refer to page 16.)
3) After completion of compensation, return the jumper to the lower pin.
REMAKS
If you start the motor in the thermistor calibration status (with the jumper of CON2 inserted in the upper pin), a motor
thermal relay alarm (E.THM) will occur in 10 seconds and the inverter output is shut off.
Likewise, if you start the motor without the thermistor interface being connected, a motor thermal relay alarm
(E.THM) will occur in 10 seconds and the inverter output is shut off.
