7.1.10 Drag error
If the load moment prevents the drive from achieving the target rpm, the current position will not
agree with that for the target rpm, a situation that can cause problems when multiple drives are
running in parallel. The ‘drag error’ parameter allows the user to establish the maximum
discrepancy. This bit is activated if the difference exceeds that of the set value; the run is not
interrupted. The action required to eliminate this problem must be monitored by the external
control unit.
7.1.11 Invalid target/parameter value
The operator has attempted to enter a target value or a parameter that lies outside of the valid
range.
7.1.12 Positioning error
After the positioning run, the difference between the actual and target values is larger than the
positioning window. The bit is deleted during the subsequent positioning run.
7.1.13 Manual rotation
Following a positioning run, an external load moment was applied to the drive, rotating it out of its
final position.
7.1.14 No supply voltage available to motor
The power supply to the motor fell below a value of roughly 17 V. Deleting this bit requires a 1
0
transition for the confirmation bit in the command byte.
7.1.15 Upper range limit
The drive has exceeded the upper limit of the user-defined positioning range and can no longer
move in the positive direction. This bit is deleted as soon as the drive is within the permissible
range. If the drive is switched off in this position, the instrument may produce positioning errors
when switched back on.
7.1.16 Lower range limit
The drive has exceeded the lower limit of the user-defined positioning range and can no longer
move in the negative direction. This bit is deleted as soon as the drive is within the permissible
range. If the drive is switched off in this position, the instrument may produce positioning errors
when switched back on.
7.2
Actual position
In this modul the drive is sending current actual position in target-value increments
