Table E.2 - Alarm Codes (Continued)
CODE DISPLAY DESCRIPTION
A00032 SUSTAINED
SPEED
Motor speed did not fall below the STOP SPEED THRESHOLD (P.113) in
the required amount of time during a stop (this time is automatically set
to two times the
DECELERATION RATE (P.002) time).
Possible causes:
• DECELERATION RATE not set properly.
• STOP SPEED THRESHOLD not set properly.
• Overhauling load maintaining motor speed higher than the STOP
SPEED THRESHOLD .
• Incorrect speed/voltage feedback scaling.
A00033 SUSTAINED
ARMATURE
CURRENT
Armature current was unable to reach discontinuous conduction while
stopping the drive.
Possible causes:
• Motor CEMF too high or line voltage too low for proper commutation.
A00050 CML FEEDBACK
SCALING ERROR
Armature current feedback could not be scaled properly based on the
values entered for
MOTOR RATED ARM AMPS and MAXIMUM CURRENT .
Verify that these parameter values are correct for your application.
Verify that
CT TURNS RATIO has been set to the value shown in the
instruction manual based on your drive type.
A00051 LOW MINIMUM
SPEED
The MINIMUM SPEED value is less than 10% of the MAXIMUM
SPEED value. This alarm will not be triggered on power-up. It only
occurs when maximum or minimum speed has changed.
Verify that these parameter values are correct for your application.
A00052 NEG CUR LIM INV
ENABLE CHANGED The parameter NEG CUR LIM INV EN (P.226) has changed state, either
enabling or disabling the negative current limit inverters. The
parameters
POS CURRENT LIMIT SEL (P.223) and NEG CURRENT LIMIT
SEL (P.224) have been automatically set to REGISTER - The user should
carefully examine the current limit scheme to avoid unintended
operation by the drive.
A00700 RETENTIVE
MEMORY SAVE
ERROR
An attempt to save information (parameter values, fault log data or the
keypad reverence value) to retentive memory failed. The drive may
continue to be operated.
Possible cause: Regulator board failure.
