NOTE 1:
If a trip occurs, press the RESET key or short the reset terminal RS-CM1 assigned as a control
circuit terminal after a delay of 10 seconds.
NOTE 2: A trip can be cleared by pressing the RESET key or shorting the reset terminal RS-CM1 assigned
as a control circuit terminal. Resetting the power supply cannot clear a trip. (To reset the power supply is
to turn power off and turn it on again after the CHARGE lamp at the upper right corner of the control PC
board goes off.) Check again whether the set data is correct.
NOTE 3: Power OFF during motor deceleration may cause an input phase failure error.
NOTE 4: The instantaneous ride-thru period of 15ms may be shortend depending on the power supply voltage or load.
NOTE 5:
When the J-FB is installed, an error is displayed for each factor as shown below.
Encoder line break:
Overspeed:
Positioning error:
Thermistor line break:
Motor overheat:

An error occurs in the optional connection (connector, etc.).
An error message outputted from the optional PCB
When a phase failure is detected on the receiving side {R(L1), S(L2), T(L3)}
of the inverter, the output is cut off. (NOTE 3)
The detector which is built in the power module operates.
When the output side of the inverter is shorted or the motor is
restricted, a large current flows through the inverter and causes a
fault. Therefore, when a current in the power module or an
abnormal temperature of the main device is detected and it
exceeds a specified value, the output is cut off.
