DRIVE SYSTEM FAULT CODES (500-LEVEL CODES)
Table 16 below lists the fault codes associated with the
drive system. Included in this table are the available
fault codes, a description of each fault code, and the
suggested corrective action to clear the fault.
NOTE: All 500-level codes are warnings indicat-
ing the maximum allowable value has
been exceeded. The door will operate only
in the failure error jog mode.
Table 16
DOOR POSITION FAULT CODES
Table 17 lists the fault codes associated with the posi-
tion of the door. Included in this table are the available
fault codes, a description of each fault code, and the
suggested corrective action to clear the fault.
NOTE: The encoder is sensitive to electromag-
netic interference (EMI) and many of the
F:700 codes are the result of electromag-
netic interferences. The encoder cable
should be installed in conduit with low volt-
age wiring.
The encoder cable must be separated from
the high-voltage wiring. All cables must be
cut to length. DO NOT wrap up excess cable
near the motor or in the control panel.

Description Corrective Action
F.510
(Mtr OC L2)
(motor over current
limit 2)
Over current.
1. Mechanical problem
2. Motor brake not releasing
3. Motor torque boost incorrectly set
4. Motor nameplate parameters (frequency,
current, etc.) incorrectly set
1. Check operation of door
2. Check brake
3. Consult factory
F.515
(Mtr OC Ext)
(motor over current
external)
Maximum motor over current.
1. Motor or motor connection problem
2. Incorrect motor parameters
3. Incorrect motor nameplate parameters
1. Check motor: Turn off power, discon-
nect motor leads and ground. Ohm wind-
ings T1-T2, T2-T3, and T1-T3 readings
should be comparable. Also ohm each
motor lead to ground, motor should not
ohm to ground.
2. Consult factory
F.519
(IGBT OC)
(insulated gate bipolar
transistor over current)
IGBT over current.
1. Faulty motor winding or motor shorted to
ground
2. Incorrect motor parameters
3. Incorrect motor nameplate parameters
1. Check motor: Turn off power, discon-
nect motor leads and ground. Ohm wind-
ings T1-T2, T2-T3, and T1-T3 readings
should be comparable. Also ohm each
motor lead to ground, motor should not
ohm to ground.
2. Consult factory
F.525
(Power OV)
(power over voltage)
High supply voltage (>+10%).
1. Incoming voltage too high 1. Check incoming voltage, check param-
eter P:940 = incoming voltage to control
