CODE

DESCRIPTION

A00032 SUSTAINED

SPEED

Motor speed did not fall below the

STOP SPEED THRESHOLD (P.113)

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

- 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.
