PI2: Actual speed
The power section "PFA-..." returns the current actual speed value to the PLC. The
exact actual speed can only be sent back when the power section can determine the
actual motor speed using speed feedback. For applications with slip compensation,
the deviation from the real motor speed depends on the accuracy of the adjusted slip
compensation.

PI3: Active current
The power section "PFA-..." returns the active actual current value of the output cur-
rent as a relative value in percentage to the PLC. The output current refers to the
