correctly (drive capacity is checked when
the drive is powered up)
Hardware is damaged.
• If the problem continues, replace the control board or the entire drive.
Contact Magnetek for instructions on replacing the control board.
CPF25
No Tmnl Card
Terminal Board not Connected

A/D Conv Flt
A/D Conversion Error:
An A/D conversion error or control
circuit error occurred.
A/D conversion is damaged; control circuit is damaged.
• Cycle power to the drive.
• If the problem continues, replace the control board or the entire drive.

CrST
(alarm)
Cannot Reset
A fault reset command was entered while the Run command was still present.
• Ensure that a Run command cannot be entered from the external terminals
or option card during fault reset.
• Turn off the Run command.
dEv
Speed Dev Flt
Speed Dev Alm
The deviation between the speed
reference and speed feedback is greater
than the setting in Spd Dev Flt Lvl
(A1)and Spd Dev Flt Time (A1).
Load is too heavy.
• Reduce the load.
Accel/decel ramp is too short.
• Lower the acceleration and deceleration rates in the A2 menu.
The load is locked up.
• Check the machine and hoistway.
Parameters are not set appropriately.
• Check the settings of parameters Spd Dev Flt Lvl (A1) and Spd Dev Flt
Time (A1).
The motor brake is not applied.
• Ensure the motor brake picks when the drive is running.
dv1
Z Marker Lost
The motor turned one full rotation
without the Z Pulse being detected.
Encoder is not connected, not wired properly, or is damaged.
• Make sure the encoder is properly connected and all shielded lines are
properly grounded.
• If the problem continues after cycling power, then replace either the PG
option card or the encoder itself.
dv2
Encod Out Of Tol
The Z pulse is out of phase by more than
5 degrees. Contact Magnetek for more
details.
Noise interference along the encoder cable.
• Separate the encoder cable lines from the source of the noise.
Encoder cable is not wired properly.
• Rewire the encoder and make sure all shielded lines are properly grounded.
PG option card or the encoder is damaged.
• If the problem continues after cycling power, replace the PG option card or
the encoder.
