4 - GENERAL PARAMETERS, DESCRIPTION
4 - 26 GV3000/SE 49'1329 e
P.043 Fault Auto Reset Attempts
Parameter Range: 0 to 10 attempts
Initial Setting: 0
Type: Configurable (in standby only)
Refer to: P.044 Fault Auto Reset Time
Description: This parameter selects the number of times the drive will attempt to reset drive faults.
NOTE: The drive will re-start after an Auto Reset attempt if the start input of the selected control
source is still asserted.
NOTE: Auto reset will be disabled during the vector self-tuning operation and the V/Hz identification
procedure.
If the auto reset feature is enabled (P.043 is not equal to 0), faults detected while the drive is
running are logged and reset. The drive will then wait the amount of time specified in P.044 (Fault
Auto Reset Time) and, if the Start input is asserted from the selected control source, start the drive
automatically.
If the fault occurs again, the drive will wait and try to re-start up to the programmed number of
attempts. If the drive faults on all of these attempts could not be reset, the drive will remain in the
faulted state and will display the fault code on the keypad/display.
The following faults can be auto reset:
Fault Code Description Fault Code Description
AIn 4 to 20 mA analog input signal loss OC Overcurrent (steady state)
bYC DC-Bus charging bypass contactor OCA Overcurrent (at acceleration)
EC Earth current failure OCb Overcurrent (at DC-braking)
HIL High line voltage OH Drive Overtemperature
HU High DC-Bus Voltage OL Overload
LU Low DC Bus Voltage UbS Asymmetrical Bus charge
nCL Network Communication Loss
All other faults cannot be auto reset:
WARNING
This function can cause an AUTOMATIC START OF THE DRIVE. The user is responsible for
assuring safe conditions for operating personal by providing devices to indicate that the drive can
start automatically after an fault auto reset. Failure to observe this precaution could result in severe
bodily injury.
P.044 Fault Auto Reset Time
Parameter Range: 1 to 60 seconds
Initial Setting: 8 seconds
Type: Configurable (in standby only)
Refer to: P.043 Fault Auto Reset Attempts
Description: This parameter specifies the amount of time the drive will wait to attempt to reset
drive faults. Note that the drive must run for at least five (5) minutes in order to
reset the number of fault reset attempts to the value in P.043.
Note: After the drive has detected the fault and is counting down the auto-reset time period, the display
will flash the countdown period in seconds in the following format:
"Ar30...Ar29...Ar28.........Ar01...Ar00"
If during this countdown, the user presses the keypad STOP/RESET key, or asserts the fault reset from
the selected control source, the auto-reset countdown will stop, and all faults will be reset.
