5.1 Identifying Alarm Codes and Recovering

GV3000/SE drive alarm codes are shown in table 5.1. 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 5.1 – List of Alarm Codes

Code

Alarm

Description

Alarm Cause

Corrective Action

AIn

Analog input signal

loss

P.011 = 8, 9, 10, or 11 and the 4 to

20 mA input is below 2 mA.

Verity that P.011 is set correctly.
Check that the analog input source

supply is

≥ 4 mA

HIdc

High DC bus

voltage

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.)

Increase the deceleration time in

P.002, P.018.
Install optional snubber resistor

braking kit.
Verify that the AC input is within

specification. Install an isolation

transformer if required.
Check the actual line voltage against

U.018.

I-Ac

V/Hz identification

procedure active

V/Hz identification procedure is

enabled and in progress.

Allow identification procedure to

finish.
Press keypad STOP/RESET to

cancel identification procedure if

desired.

I-En

V/Hz identification

procedure

enabled

H.020 = On; V/Hz identification

procedure has been enabled but not

started.

Proceed with V/Hz identification

procedure, start drive and allow

procedure to begin. Display will

change to I-Ac when drive is started.
Change H.020 to OFF to cancel

identification and clear I-En if

desired.

LIL

Low AC input line

AC input line is low.
For SVC, indicates DC bus is being

regulated. No corrective action is

required.

Adjust line voltage parameter (H.021

or U.018) to match actual AC line

voltage.

S-Ac

Vector self-tuning

active

Vector self-tuning is enabled and in

progress.

Allow vector self-tuning procedure to

finish.
Press keypad STOP/RESET to

cancel vector self-tuning procedure

if desired.

S-En

Vector self-tuning

enabled

U.008 = On; vector self-tuning has

been enabled but not started.

Proceed with vector self-tuning, start

drive and allow self-tuning

procedure to begin. Display will

change to S-Ac when drive is

started.
Change U.008 to OFF to cancel

self-tuning and clear S-En if desired.
