TROUBLESHOOTING
DRIVE FAULT / ENCODER FLT
1.
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.
Verify that “C1 - Encoder Select” is set to “
Axial Flux
”.
d.
Swap A+ / A- on terminal TB2 – #1 (A) and #2 (/A).
i.
After changing any encoder wiring the Encoder Alignment
must be ran again (See page 6).
BRAKE NOT LIFTING
1.
If the brake is not picking make sure that it is wired according to
Sheet 5 – Brakes 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 / K2 and J1 / J2. Verify the voltages are also at the Brake
Coil(s) when commanded to pick.
b.
Verify that the voltages match the Brake Coil voltages shown
on “Sheet 1: Getting Started” table.
WRONG DIRECTION
1.
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.
Change the direction of the motor in the drive by going to “C1
– Motor Rotation” and toggling between FORWARD/
REVERSE.
c.
Swap two of the motor leads (T1 with T2). After swapping the
motor wires it may be necessary to change C1 – Motor
Rotation again. Run the U12 Auto Tune again.
