Possible reason for error
Overvoltage in DC-bus Limit 2
• Brake chopper interference / defective / missing
• Incoming mains voltage much to high
• Motor is generating excessive voltage - brake chopper cannot dissipate the
re-generated energy
• Input voltage supply too low, usually at load
• Load too great / final stage or brake chopper fault
ext. 24 V supply missing or too low
• Overload but no short circuit
• When 24V is shorted the controller voltage does not ramp up and glow lamp
V306 comes on.
Overvoltage at the incoming mains supply
• The incoming mains supply for the Controller is to high
• The incoming mains supply fluctuates very extremly
Heatsink temperature outside of working range Limit
2
• Too high load on the power amplifiers or the brake chopper
• Clock frequency of the power amplifier too high (Parameter P.160)
• Surrounding temperature too low for operation of the controller
• The temperature inside the controller housing is to high
Overcurrent in DC-bus Limit 2
• Boost not adjusted
• Motor incorrectly dimensioned for door
• Door sticks
Bad light curtain reception quality
Poor reception quality when the light curtain is started
• Light curtain dirty
• Protection foil not removed
• bad aligned
• wrong Range set
Light curtain light line alignment
Light line alignment has not been done
• Too less increments
Light curtain light line position values not plausible
Position values stored by the light curtain do not match door movement
• Objects in the door area during teach in
RS-485 communication failure between Receiver and Door Controller
• Insufficient valid position data
• A and B wires twisted
• wrong connection.
RS-485 communication error between Transmitter and Receiver
• A and B wires twisted
• wrong connection
