Motor does not rotate after the parameters were transmitted from a drive that uses less power than the one the parameters were transmitted to (eliminated from V5.0 onwards)

Eliminated from:
StateLine / HighLine with firmware version V05.01 or higher

Behaviour of the new version?
This function restriction is eliminated with the above-mentioned firmware version.



Which products are affected?
8400 StateLine  4.x/ HighLine with FW 4.0

What happens?
After the parameters were transmitted from a drive that uses less power (e.g. 370 W) than the one the parameters were transmitted to (e.g. 15 kW), the motor does not rotate in the 'VFCplus: V/f linear' control mode.

When does the problem occur?
If a data set is created in a small drive and if this configuration is then transmitted into a drive that uses more power, the data of the smaller motor are also transmitted.
In the above-mentioned affected devices, the motor data (C0088) also influence the drive behaviour in the 'VFCplus: V/f linear' operating mode.

Possible diagnostics?
Check the value in C0088.

Short-term measures / recommendations?
Enter the correct rated motor current (C0088) after the parameters were transmitted from a drive that uses less power than the one the parameters were transmitted to.

Evaluation:
If C0088 has not been parameterised correctly, it will show immediately during initial commissioning.
