8AT_SETPOINT1 OPERATING. Actual value equals reference value (= is
within tolerance limits, ie the difference between the output
frequency and the frequency reference is less than or equal
to 4/1%* of the nominal motor frequency).
* Asymmetric hysteresis: 4% when frequency enters the
reference area, 1% when frequency exits the reference
area.
0 Actual value differs from reference value (= is outside
tolerance limits).
9 REMOTE 1 Drive control location: REMOTE (EXT1 or EXT2)
0 Drive control location: LOCAL
