OPF

MOTOR PHASE LOSS

1. Loss of a phase on the output of the

drive controller.

2. Drive controller oversized for motor.

1. Check the wiring to the motor (Procedure 3 on

page 90).

2. Disable OPL and provide external overload

protection.

OSF

OVERVOLTAGE

Supply too high. See Table 26. 1. Check input line voltage (Procedure 2 on page 89).

2. Reset the drive controller.

OtF

MOTOR OVERHEATING

Motor temperature too high. 1. Check the motor ventilation, ambient temperature,

and motor load.

2. Check the type of thermal sensors used.

PHF

INPUT PHASE LOSS

1. Input phase loss.

2. Power fuses blown.

3. Input line failure (t > 1s).

1. Check input line voltage (Procedure 2 on page 89).

2. Check fuses and circuit breaker (Procedure 3 on

page 90).

3. Reset.

rnF

RAMP NOT FOLLOWED

1. Ramp not followed.

2. Speed opposite from reference.

1. Check the adjustment and wiring of the speed

feedback.

2. Check the adjustments against the load.

3. Check the sizing of the motor/drive controller

combination. Dynamic Braking may be necessary.

SCF

MOT SHORT CKT

Short circuit or grounding on drive

controller output.

1. Remove all power. With drive controller

disconnected, check connecting cables and motor

insulation.

2. Check the drive controller transistors.

SLF

LOSS OF RS485

Bad connection between the drive

controller and the programming keypad

display.

Check the connection between the drive controller

and the programming keypad display.

SOF

OVERSPEED

1. Instability.

2. Overhauling load.

1. Check parameter adjustments.

2. Add Dynamic Braking.

3. Verify the sizing of the motor, drive controller, and

load.

SPF

SPEED FEEDBACK

FAULT

Loss of speed feedback. Check the wiring of the sensor.

tSF

THERMAL SENSOR

FAULT

Bad connection between the motor

thermal sensors and the drive controller.

1. Check the connection between the thermal sensors

and the drive controller.

2. Check the thermal sensors.

USF

UNDERVOLTAGE

1. Supply is too low.

2. Temporary voltage drop (t

≥ 200 ms).

Check input line voltage (Procedure 2 on page 89).
