1 OPERATING. Actual value equals reference value (= is within tolerance limits, i.e in
speed control the speed error is less than or equal to 4/1%* of the nominal motor
speed).
* Asymmetric hysteresis: 4% when speed enters the reference area, 1% when
speed exits the reference area.
0 Actual value differs from reference value (= is outside tolerance limits).
1 Drive control location: REMOTE (EXT1 or EXT2)
0 Drive control location: LOCAL
1 Supervised parameter value exceeds the supervision high limit. Bit value is 1 until

0 Supervised parameter value falls below the supervision low limit. Bit value is 0 until
the supervised parameter value exceeds the supervision high limit. See parameter
