Altivar Process ATV600 and Speed error in Profidrive ZSW1.8 when controlling drive on Profinet

The speed error (also known as velocity error) is the difference between the target speed setpoint and actual speed. If this value exceeds the speed error tolerance while controlling speed PID, the bit will signalize out of tolerance range.
The tolerance range cannot be set by a simple parameter. The tolerance range depends on speed loop setting (proportional gain, integral time).
This speed error bit exists on profinet/profidrive only. For other communications, ETA does not have this bit.
