Description
Possible reason for error
F.420
Overvoltage in DC-bus Limit 1
• Brake chopper interference / defective / missing
• Feed voltage much to high
• Motor is generating excessive voltage - brake chopper cannot dissipate the re-generated energy.
F.425
Overvoltage line supply
• The supply voltage for the controller is to high
F.426
Undervoltage line supply
• The supply voltage for the controller is to low
F.430
Temperature heat sink outside of
working range Limit 1
• Excessive load on power stage or brake chopper
• Ambient temperature too low for controller operation
• Clock frequency of power stage too high (Parameter P.160)
F.435
Housing temperature high
• The temperature inside the controller housing is to high
F.440
Overcurrent in DC-bus Limit 1
• Boost not adjusted
• Motor incorrectly dimensioned for door
• Door sticks
F.510
Motor / DC-bus overcurrent Limit 2
• Wrong motor data set (P.100–P.103)
• Non-adjusted voltage increase / boost set (P.140 or P.145)
• Motor not properly dimensioned for door
• Door sticks
F.511
No DC supply
• The DC voltage can not given to the motor (overcurrent error, IGBT error F.519, 24 V error or over temperature)
• The emergency stop is activated
F.512
Offset motor current / link current
incorrect
• Hardware faulty
F.515
Motor protection function detected
overcurrent
• Incorrect motor curve (motor rated current) set (P.101)
• Too much boost (P.140 or P.145)
• Motor incorrectly dimensioned
F.519
IGBT driver chip detected
overcurrent
• Short circuit or ground fault on motor terminals
• Motor rated current setting extremely wrong (P.100)
• Extremely too much boost (P.140 or P.145)
• Motor incorrectly dimensioned
• Motor winding defective
• Momentary interruption of the E-Stop circuit.
F.520
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
F.521
Low voltage in DC-bus
• Input voltage supply too low, usually at load
• Load too great / final stage or brake chopper fault
F.524
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.
F.525
Overvoltage at the incoming mains
supply
• The incoming mains supply for the Controller is to high
• The incoming mains supply fluctuates very extremly
