Notes:
−
M1SpeedMin (20.01) is must be set in the range of 0.625 to 5 times of M1BaseSpeed (99.04). If the
scaling is out of range A124 SpeedScale [AlarmWord2 (9.07) bit 7] is generated.
−
M1SpeedMin (20.01) is also applied to SpeedRef4 (2.18) to avoid exceeding the speed limits by means of
SpeedCorr (23.04).

20.03 M1ZeroSpeedLim (zero speed limit)
When the Run command is removed [set UsedMCW (7.04) bit 3 to zero], the drive will stop as chosen by
StopMode (21.03). As soon as the actual speed reaches the limit set by M1ZeroSpeedLim (20.03) the motor
will coast independent of the setting of StopMode (21.03). Existing brakes are closed (applied). While the
actual speed is in the limit, ZeroSpeed [AuxStatWord (8.02) bit 11] is high.

20.05 TorqMax (maximum torque)
Maximum torque limit - in percent of MotNomTorque (4.23) - for selector TorqUsedMaxSel (20.18).
Note:
The used torque limit depends also on the converter's actual limitation situation (e.g. other torque limits,
current limits, field weakening). The limit with the smallest value is valid.

20.06 TorqMin (minimum torque)
Minimum torque limit - in percent of MotNomTorque (4.23) - for selector TorqUsedMinSel (20.19).
Notes:
−
The used torque limit depends also on the converter's actual limitation situation (e.g. other torque limits,
current limits, field weakening). The limit with the largest value is valid.
−
Do not change the default setting of TorqMin (20.06) for 2-Q drives, because M1CurLimBrdg2 (20.13) is
internally set to 0 % if QuadrantType (4.15) = BlockBridge2 (2-Q drive).

Note:
The used torque limit depends also on the converter's actual limitation situation (e.g. other torque limits,
