Cause
•
Remedy
E013 / E14.6
Diff. betw. abs./inc.
Difference between absolute and
incremental encoder
•
Check controller settings in P631 and
position acquisition
•
Position change in absolute and
incremental encoder does not match
E013 / E14.7
Max. pos. overshot
Maximum position exceeded
•
Check controller settings in P615 and
setpoint specifications
E013 / E14.8
Min. pos. undershot
Minimum position undershot
•
Check controller settings in P616 and
setpoint specifications
7.2 Table of error sources
The following table lists the main sources of error and the corresponding symptoms. It is recommended that, when
troubleshooting, the same sequence should be implemented as in commissioning, i.e. first check whether the axis
is running unregulated and then test the speed and position control.
1. Error sources when operating in servo mode (without position control)
Symptom
Additional test
Possible cause
Change sign in P301
•
Incorrect assignment of motor
direction to incremental encoder
direction
Motor only turning slowly, motor
jerky
•
Incorrect incremental encoder
type (no RS422 outputs)
•
Encoder line interrupted
•
Encoder power supply missing
•
Incorrect pulse number
parameterised
•
Incorrect motor parameters
•
An encoder track is missing
Motor turning correctly, but jerky at
lower speeds
Overcurrent switch-off at higher
speeds
Problems disappear when servo
mode switched off
•
Incremental encoder incorrectly
mounted
•
Faults in encoder signals
Overcurrent switch-off during
deceleration
Motor in field weakening operation
•
The torque limit must not exceed
200% for field weakening
operation in servo mode
