Which products are affected?
Starttec, all designs for multi-motor operation or changes in direction of rotation, up to and including SW version 1.3.
What happens?
The digital output function 'Apparent current < Current threshold' does not work in case of anti-clockwise rotation. In case of anti-clockwise rotation, the code C0054 does not indicate a current.
When does the problem occur?
If the apparent current (C0054) exceeds the current threshold (C0156) in case of anti-clockwise rotation, the function 'Apparent current < Current threshold' does not set the corresponding digital output to HIGH level. If the motor is operated in anti-clockwise rotation, code C0054 will not indicate a current.
Possible diagnostics?
Reading out the code C0054 during anti-clockwise rotation.
Short-term measures/recommendations?
None.
Evaluation:
Due to this error the function 'Apparent current < Current threshold' cannot be used in case of anti-clockwise rotation. An incorrect behaviour of the drive can already be detected during commissioning.
