6.12.3 Retry function

H : Retry selection (Selecting the number of times)

Caution

Do not go near the motor in alarm-stop status when the retry function is selected. The motor may suddenly restart, which could result in injury.

Mandatory Take measures for safety, e.g. attach a cover to the motor, to prevent accidents if the motor suddenly restarts.

Function

This parameter resets the inverter automatically when the inverter gives an alarm. During the retry mode, the motor speed search function operated automatically as required and thus allows smooth motor restarting.

+The retry function is disabled in the following unusual events:

QEC : Arm overcurrent at start-up

GTT : Main unit RAM fault

QEN : Overcurrent on the load side at start-up GTT : Main unit ROM fault

GRJQ : Output phase failure

GTT : CPU fault trip

QJ : External thermal trip

GTT : Remote control error

QV

: Overtorque trip

GTT : Current detector fault

G

: External trip stop

GTT : Control circuit board format error

WE : Small-current operation trip

GGR : EEPROM fault 1

WR : Undervoltage trip (main circuit)

GGR : EEPROM fault 2

GH : Ground fault trip

GGR : EEPROM fault 3

GRJ : Input phase failure

GVP : Auto-tuning error

GV[R : Inverter type error

G : VIA input detection error

 

 

G : Main unit CPU communication error

 

 

G : Excessive torque boost

 

 

G : CPU fault 2
