Troubleshooting
The following sections list troubleshooting procedures.
Drive Fault / Encoder Fault
The most common fault at startup with a Magnetek drive is the Encoder fault.
Perform the following checks to correct this fault:
•
Check for a solid shield-to-ground connection at the motor and drive.
•
Check for correct colored encoder wires to the terminals.
•
Swap A+ / A- on terminal TB1.
Brake Not Lifting
If the brake is not picking, make sure that the brake is wired according to
C4 Controller
sheet
05
Brake Connection
and if there is a second brake installed, verify that the EB terminal is
jumpered to the terminal. See the
C4 Controller
sheet
01 – Getting Started
for more
information.
If the brake has the proper voltage check the following:
•
During a run command, check the DC voltage between points K1 / K2 and J1 / J2 if
secondary brake is installed. Verify the voltages are also at the brake coil(s) when
commanded to pick.
•
Verify that the actual brake voltage matches the brake coil voltage shown on the
C4
Controller
sheet
01 – Getting Started
Parameter table.
Wrong Direction
If the car is moving in the wrong direction check the following:
•
On the Smartrise Controller board, make sure that IO CUP comes on when commanding
the
UP
direction and IO CDN comes on when commanding the
DOWN
direction.
•
Swap two of the motor leads (T1 with T2).
Car Moving to Slow or Rough
If the car is moving to slow or rough perform the following:
•
Swap the encoder wires A+ and A- on drive TB1.
•
Verify the brakes are lifting fully.
