Trouble-Shooting
The following list refers to faults which can occur during operation.
Display:
Error
Explanation and remedy
no motor run despite current flow
motor mechanically blocked?
motor brake released?
1)
motor runs unevently
check setpoint wiring
check grounding and shielding
too high P-amplification in the speed controller
reduce value
(with EASYRIDER
setting/speed control)
too small I-time in the speed controller?
reduce value
(with EASYRIDER
setting/speed control)
no reaction of setpoint progression, despite
torque in standstill
Limit switch functions
effective (BIAS)
no current flow;
no torque despite activating the regulator
correctly
motor cables interrupted?
Is input "I extern" (X10.19) activated
(config. menu) and not notched up?
limit switch - input
activated and not notched up?
Interference symptoms with power frequency Ground loops in setpoint or actual value wiring?
Shieldings laid on both sides?
Signal cables near high voltage cables?
Motor takes up preferred positions after
activation
Position encoder or motor cables with reversed
poles?
Resolver or Feedback- encoder incorrectly adjusted?
Number of motor poles wrong matching? (config.
menu)
1)
Motor runs up immediately after activation
although there is no setpoint
Motor cables or feedback- cables reversed? Encoder
incorrectly adjusted?
(e.g. Resolver)
1)
Motor reaches in idling cycle very different
speed when running to the right or to the left
Feedback-Encoder incorrectly adjusted
(e.g. Resolver)
1) Display
or
mostly short after activating; before warning
