2.6.18 Spindle speed.
SZERO
Speed considered "0 rpm".
Parameter valid for spindles.
Parameter valid for analog drives and simulated drives.
Possible values: From 0 to 100000 rpm.
Default value: 1.
Associated variable: (V.)[ch].MPA.SZERO[set].xn
This parameter indicates the rpm value below which the spindle is considered to be stopped.
The CNC uses this parameter to switch the spindle to C axis mode and also to accept the
velocity command programmed with SANALOG when the spindle is controlled from the PLC.
This parameter can also be used from the PLC to permit opening the machine doors.
POLARM3
Sign of the velocity command for M3.
Parameter valid for spindles.
Parameter valid for analog drives, velocity-Sercos drives and simulated drives.
Possible values: Positive / Negative.
Default value: Positive.
Associated variable: (V.)[ch].MPA.POLARM3[set].xn
See machine parameter POLARM3.
POLARM4
Sign of the velocity command for M4.
Parameter valid for spindles.
Parameter valid for analog drives, velocity-Sercos drives and simulated drives.
Possible values: Positive / Negative.
Default value: Negative.
Associated variable: (V.)[ch].MPA.POLARM4[set].xn
Lathe and mill models.
Parameters POLARM3 and POLARM indicate the direction of the velocity command and,
therefore, the spindle turning direction for functions M3 and M4 respectively.
The CNC offers the following variable to reverse, via part-program or PLC, the direction of
the velocity command set in this parameter.
Laser model.
Parameters POLARM3 and POLARM indicate the direction of the velocity command for
functions M3 and M4 respectively. Both parameters must be set to "Positive".

(V.)[ch].A.POLARITY.sn
(V.)[ch].SP.POLARITY.sn This variable may be used to reverse the meaning of parameters
POLARM3 and POLARM4. The variable does not modify the values of
the machine parameters.
