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.

6		The likely causes of tripping and the corresponding retry processes are listed below.

		Cause of tripping			Retry process			Canceling conditions
		Momentary power			Up to 10 times in succession			The retry function will be canceled at
		failure			1st retry: About 1 sec after tripping			once if tripping is caused by an unusual
		Overcurrent			2nd retry: About 2 sec after tripping			event other than: momentary power
		Overvoltage			3rd retry: About 3 sec after tripping			failure, overcurrent, overvoltage or
		Overload			…			overload.
		Overheating			10th retry: About 10 sec after tripping			This function will also be canceled if
								retrying is not successful within the
								specified number of times.

+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
