Troubleshooting the FlexPak 3000 Drive

13-11

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

TIME

(P.002)).

Possible causes:

DECELERATION

TIME

(P.002) not set properly.

STOP

SPEED

THRESHOLD

(P.113) not set properly.

Overhauling load maintaining motor speed higher than the

STOP

SPEED

THRESHOLD

(P.113).

Incorrect speed/voltage feedback scaling.

A00033

SUSTAINED

ARMATURE

CURRENT

Armature current was unable to reach discontinuous conduction while
stopping the drive.

Possible cause:

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.

A00051

LOW

MINIMUM

SPEED

The

MINIMUM

SPEED

value is less than 10% of the

MAXIMUM

SPEED

value.

This alarm will not be triggered on powerup. 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

LIM

SEL

(P.223) and

NEG

CURRENT

LIM

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. Also see section 5.4, Configuring the Speed
Loop Current Limits.

A00700

RETENTIVE

MEMORY

SAVE

FAILURE

An attempt to save information (parameter values, fault log data or the
keypad reference value) to retentive memory failed. The drive may
continue to be operated.

Possible cause:

Regulator board failure.
