Troubleshooting
Drive Fault / Encoder Flt
The most common fault at startup with a Magnetek drive is the
Encoder fault. Perform the following checks to correct this fault:
a. Check for a solid shield-to-ground connection at the motor
and drive.
b. Check for correct colored encoder wires to the terminals.
c. Swap A+ / A- on terminal TB1 – #1 (A+) and #2 (A-).
i. After swapping the A signal wires it may be necessary to
change the direction of the “C1 – Encoder Connect”.
Brake not lifting
1. If the brake is not picking make sure that it is wired according to
“Sheet 5 – Brake & Hydro Options” and verify that the EB terminal
is jumped to the terminal listed on “Sheet 01 – Getting Started”. If
it has the proper voltage check the following:
a. During a run command, check for DC voltage between points
K1 and K2. Verify this voltage is also at the Brake Coil when
commanded to pick.
b. Verify the actual brake voltage matches the Brake Coil voltage
setting shown on “Sheet 1: Getting Started” table.
Wrong Direction
If the car is moving in the wrong direction:
a. On the Smartrise controller board make sure that IO 521
comes on when commanding the UP direction and IO 522
comes on when commanding the DOWN direction.
b. Swap two of the motor leads (T1 with T2).
Car moving too slow or rough
Swap A+ / A- on terminal TB1 – #1 (A+) and #2 (A-).
a. After swapping the A signal wires it may be necessary to
change the direction of the “C1 – Encoder Connect”.
Verify the brakes are lifting fully.
