IF… During reopening, the doors take too long to fully reopen:
1. Increase “Pr” incrementally. Remember that the more “Pr” is increased, the more the
possibility of inconsistency while approaching full open.
IF… During reversals, doors stop and reverse too rapidly, producing mechanical vibrations
and bumps:
1. Reduce “Ab” until reversal is smooth.
2. Check mechanical system and correct as required.
IF… During reversals, it takes too long for doors to stop and reverse:
1. Increase “Ab” until reversal is smooth.
Torque Adjustment
Door acceleration depends on door mass, friction, and applied torque. If torque is insufficient,
the set door speed value (U) will not be attained. If doors do not achieve the set speed value in a
particular direction, increase associated torque and re-learn the doors. Torque adjustment is
accomplished by setting parameters “C1”, “C3”, “Co”, “Cc”, and “Cb”.
After torque adjustments are made, learn process must be repeated. Multiple parameters affect
closing torque. Please refer to “Inverter Drive Parameters” on page 20.
IF… In close direction, door close pressure is too high:
1. Reduce “C3” until door pressure is correct.
IF… In close direction, doors stop before reaching full close and DCL is NOT generated:
1. Check for an obstruction.
2. Check for friction in door system and, if necessary, increase “C3”.
IF… In close direction, DCL is generated slightly before doors are fully closed:
1. Make sure learn process was performed correctly.
2. “C3” may be set too low. Increase “C3”.
IF… In open direction, DOL is generated slightly before doors are fully open:
1. Make sure learn process was performed correctly.
2. “C1” may be set too low. Increase “C1”.
IF… After doors reach full open and DOL is generated, doors drift toward close direction:
1. If doors drift close, increase “Co”. The value of “Co” should be set to minimum necessary
to keep doors from drifting close in order to minimize heating motor.
IF… After doors reach full close and DCL is generated, doors drift toward open position:
1. If doors drift open, increase “Cc”. The value of “Cc” should be set to minimum necessary
to keep doors from drifting open in order to minimize heating motor.
