7.1.2 MSD MD (data description - SW 3)
nmin for nact < nmin message motor 2
260
Default value Lower input limit Upper input limit Units
12 0 Rated speed rev/min
Active
at once
Input of response value for monitoring of the PLC status message nact < nmin (see also
MD 241).
Creep speed pulse suppression motor 2
261
Default value Lower input limit Upper input limit Units
Rated speed
––––––––––––––
256 0 Rated speed rev/min
Active
at once
Input of response value for the internal nmin sensor for stopping the drive with no reverse
rotation. When the speed nmin is reached, the drive torque is cut off and the drive coasts to a
stop with any remaining kinetic energy.
Note:
This nmin threshold is not the same as the response value of the nmin monitor, but it may be
set to the same value.
nx for nact. < nx message motor 2
262
Default value Lower input limit Upper input limit Units
6 000 0 Maximum motor
speed rev/min
Active
at once
Input of response value for monitoring of the PLC status message nact < nx (see also
MD 241).
Tolerance band for nset = nact message motor 2

Active
at once
Input of response value for the tolerance band of the PLC status message nset > nact (see
also MD 241). The tolerance band of the nset = nact response threshold can be defined in
machine data MD 263.
