Possible reason for error
Position sensing defective
With mechanical limit switches:
• At least one limit switch does not correspond to the configured active status.
• An implausible combination of at least 2 active limit switches.
For electronic limit switches:
• After invoking activation of the factory parameters (Parameter P.990) the
corresponding positioning system was not parameterized.
• Calibration not completed or is incorrect and must be repeated
(P.210 = 5).
• When activating the intermediate stop the intermediate stop is implausible.
• Synchronization not finished or reference switch defective.
CLOSE Position not found in timer mode
• The simulated end switch CLOSE was not reached at the expected position
• The tolerance band for the recognition time is to small (P.229)
OPEN Position not found in timer mode
• The simulated end switch OPEN was not reached at the expected position
• The tolerance band for the recognition time is to small (P.239)
Loss of communication with encoder
• Interface cable defective / interrupted
• supply voltage 12 Volt faulty, e.g. shortcut in spiral cable
• Channel A and B connected over cross
• Absolute encoder processor electronics defective
• Defective hardware or electrically noisy environment
• Use a shielded control cable
• Install a RC element (100Ω+100nF) at the brake
Position outside of window
• Position encoder drive defective
• Absolute encoder processing electronics defective
• Defective hardware or electrically noisy environment
• Position encoder drive defective -> make a reset
• The position encoder TST PD / PE is disturbed -> make a reset
• The temperature in the encoder housing is to high
• The voltage of the buffer battery is to low → change battery
Rotation speed of PD shaft to high
• The rotation speed of the shaft where the encoder is mounted is to high →
mount the encoder on another shaft
Door way is to high for the parameter set Encoder
resolution
• The Value of the Parameter P.202 (set Encoder resolution) is to high for the
combination encoder and door.
