8.3 Resetting fault trips
Follow one of the instructions below to reset the inverter:
•
From the keypad, press the [RESET] key.
•
From the inverter’s control terminal, close the circuit between the RST and
CM terminals.
•
Turn OFF the inverter, and then turn it ON again.
8.4 Troubleshooting when a fault trip occurs
When a problem occurs, confirm the followings first.
•
Are the motor and the inverter connected properly?
- Refer to page 18.
•
Is the encoder type jumper on the add-on module set correctly?
- Refer to page 33.
- If the encoder is line drive type, set JP1 to “LD”. If the encoder is complementary or open
collector type, set JP1 to “OC” and ensure that the encoder power source has been
correctly connected (check 5 V/12 V/15 V terminal connections on the add-on module
terminal block).
•
Is direction of the motor rotation correct?
- Refer to page 63.
- When looking at the motor from the motor’s fan, the motor rotates clockwise in the
forward operation.
•
Has the inverter been tested sufficiently in a no load status?
When a fault trip or warning occurs due to a protection function, refer to the
following table for possible causes and remedies.
Type
Cause
Remedy
Over Current
Acc/Dec time is too short, compared to
load inertia (GD
2
).
Increase Acc/Dec time.
