Troubleshooting Guide (mechanical)
PF9500A
Gate arm keeps going up and down Limit switch fault check and reset limit switches
Gate creaking when moving Check turn buckle Oil or grease turn buckle
Gate motor not running Loss of voltage Check motor supply test 3 phases
Gate not opening or closeing Drive shaft connections Re-connect any drive shaft connections
Gate not opening or opening half way Gearbox Gears stripped due to overlading replace
Gate opens slowly and closes too fast Lack of balance counter weight compensation Fit counter weights
Gate not running at all Door has been left open or switch not pushed in Close the door and issues a signal to open or
close
Gate opens and will not close Key switch is left in open position Turn key switch to auto
Loop fault or loop detecting Check if green light is on detector if so remove
object that it is detecting or replace loop
MECHANICAL ERRORS CAUSE CORRECTION
16
Inverter Fault detection codes that cannot be reset automatically (continued)
Code Name Possible causes Remedy
OCF Overcurrent • Parameters in the Motor control
menu drC- page 55 are not
correct
• Inertia or load too high
• Mechanical locking
• Check the parameters
• Check the size of the motor/drive/load
• Check the state of the mechanism
• Connect line motor chokes
• Reduce the
Switching frequency SFr
page 57
• Check the ground connection of drive, motor
cable and motor insulation.
SCF1 Motor short circuit • Short-circuit or grounding at the
drive output
• Ground fault during running status
• Commutation of motors during
running status
• Significant current leakage to
ground if several motors are
connected in parallel
• Check the cables connecting the drive to the
motor, and the motor insulation
• Connect motor chokes
SCF3 Ground short circuit
SCF4 IGBT short circuit • Internal power component short
circuit detected at power on
• Contact your local Schneider Electric
representative
SOF Overspeed • Instability
• Overspeed associated with the
inertia of the application
• Check the motor
• Overspeed is 10% more than
Maximum
frequency tFr page 55 so adjust this
parameter if necessary
• Add a braking resistor
• Check the size of the motor/drive/load
• Check parameters of the speed loop (gain
and stability)
tnF Auto-tuning • Motor not connected to the drive
• One motor phase loss
• Special motor
• Motor is rotating (being driven by
the load, for example)
• Check that the motor/drive are compatible
• Check that the motor is present during auto-
tuning
• If an output contactor is being used, close it
during auto-tuning
• Check that the motor is completely stopped
