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 “
endat
”.
d.
Swap A+ / A- on terminal TB2 – #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”.
ii.
After changing any encoder wiring the Encoder Alignment should
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. 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 (if 2
nd
brake installed). 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 CUP comes on
when commanding the
UP
direction and IO CDN 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.
CAR MOVING TOO SLOW OR ROUGH
1.
Swap the encoder wires A+ and A- on drive TB2 (terminals 1 & 2).
2.
Verify the brakes are lifting fully.
SETUP FAULT ONE
This is caused when the HPV is programmed with motor data (A5) that conflicts
with drive software.
