Troubleshooting/Diagnostics 4-9
Table 4.2 - Alarm Codes (Continued)
CODE DISPLAY DESCRIPTION
A00032 SUSTAINED SPEED Motor speed did not fall below 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 (P.002) not set properly.
• STOP SPEED THRESHOLD (P.113) 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 correct value for your
drive (see parameter description).
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 (no message) 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 set to REGISTER - Carefully check your current limit scheme and
the values of POSITIVE CURRENT LIM (P.005) and NEGATIVE CURRENT LIM
(P.006) to avoid unintended drive operation.
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.
