Verify DC Bus voltage

Refer to Instruction Manual 49'1327 'GV3000 Power Unit', Section 2 for Power Circuit diagrams and
Section 4 for procedure 'DC-Bus Voltage Check'.

IPHU Judgement of the current
IPHV* waveform with scope
IPHW (peak value)
(motor current feedback
across burden resistor)
* Pin IPHV on Type 003-030 and 039/044 only

Identifying Alarm Codes and Recovering

GV3000/SE drive alarm codes are shown in Table 7.1. Note that the alarm code will only be displayed
for as long as the problem exists. Once the problem has been corrected, the alarm code will disappear
from the display.
Table 7.1 - List of Alarm Codes
Code Alarm Description
Ain Analog input signal loss
HIdc High DC bus voltage
Ar.. Auto-reset
The display will flash the
countdown period in
seconds in the following
format:
"Ar30..Ar29..Ar28......
.Ar01..Ar00"

Alarm Cause
P.011=8, 9, 10 or 11 and the
4 – 20 mA input is < 2 mA
The DC bus is charged above
the trip threshold.
(If U.018 > 415, DC bus is
above 741 VDC.
If U.018 ≤ 415, DC bus is
above 669 VDC.)
The drive has detected a fault
and is counting down the auto-
reset time period.
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.
V/Hz identification procedure is
enabled and in progress.
H.020 = ON; V/Hz identification
procedure has been enabled
but not started.

Corrective Action
Verify that P.011 is set correctly.
Check that analog input source supply ≥ 4 mA.
Increase the deceleration time in P.002, P.018.
Install optional snubber resistor braking kit DBU.
Verify that the AC input is within specification. Install
an isolation transformer if required.
Check the actual line voltage against U.018.
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.
1. Allow identification procedure to finish.
2. Press keypad STOP/RESET to cancel identification
procedure if desired.
1. Proceed with V/Hz identification procedure, start
drive and allow procedure to begin. Display will
change to I_Ac when drive is started.
2. Change H.020 to OFF to cancel Identification and
clear I_En if desired.
