Parker Hannifin G2 manual Error number

Error number	20	Power module error
			Long:
			PowerModuleError
Error type:	[KIND_RGR] Always error		Short:
Measures:	[TYPE_SRV] Servo OFF		PwrMdlErr
Main cause:	A power module error in the driver was detected.
	[Subcode]

1:Over-voltage (over-voltage of main power supply)

2:Over-current (over-current detected, 1 PM fault)

Action to take:

Error number	21	AC power error
			Long:
			AC_PowerError
Error type:	[KIND_SRV] Servo error		Short:
Measures:	[TYPE_SRV] Servo OFF		AC_PwrErr
Main cause:	Either the main power supply is not input or the input voltage has not reached the rating level.
Action to take:	Verify the main power supply.
Error number	22	Over load
			Long:
			Overload
Error type:	[KIND_RGR] Always error		Short:
Measures:	[TYPE_ELS] Others		Overload
Main cause:	The motor use is overloaded.
	[Subcode]
	1: The motor is overheated.
	2: The power module heat sink is overheated.
Action to take:
Error number	23	Excessive position deviation
			Long:
			OverPerr
Error type:	[KIND_SRV] Servo error		Short:
Measures:	[TYPE_ELS] Others		OverPerr
Main cause:	The position deviation was greater than the tolerance.
Action to take:	Perform the servo adjustment again. If an error still occurs, extend the tolerance.
Error number	24	Over speed
			Long:
			OverSpeed
Error type:	[KIND_RGR] Always error		Short:
Measures:	[TYPE_ELS] Others		OverSpeed
Main cause:	The velocity was higher than the maximum velocity.
Action to take:
