MACHINE PARAMETERS
SOFT: V02.2X
Spindle parameters
POLARM3 (P7) POLARM4 (P8)
Indicates the sign of the spindle velocity command for M03 and M04.
If the same value is assigned to both parameters, the CNC will output a single polarity (0V to 10V)
command with the indicated sign.
SREVM05 (P9)
This parameter is used with a Mill model CNC. It is not used for the second spindle.
Indicates whether it is necessary or not to stop the spindle (M05) when reversing rotation direction
during a tapping canned cycle (G84).
MINSOVR (P10) MAXSOVR (P11)
Indicate the minimum and maximum % applicable to the programmed spindle speed. It is not used
for the second spindle.
The resulting speed will be limited to the value indicated by spindle parameter MAXVOLT1 (P37),
MAXVOLT2 (P38), MAXVOLT3 (P39) or MAXVOLT4 (P40) corresponding to the selected gear.
SOVRSTEP (P12)
Indicates the incremental step of the programmed spindle speed every time the override keys at
the operator panel are pressed. It is not used for the second spindle.
NPULSES (P13)
Indicates the number of pulses per revolution provided by the spindle encoder. 0 means that there
is no spindle encoder.
It must be set when the drive's velocity command is analog; it is sent via Sercos (DRIBUSLE = 0)
or via CAN (DRIBUSLE = 0 or 1).
When the main spindle does not have an encoder (NPULSES=0), the CNC shows its theoretical
rpm (affected by the %).
Value Meaning
+ sign Positive command.
- sign Negative command.
Default value: For POLARM3 (P7) = + sign.
For POLARM4 (P8) = - sign.
Value Meaning
EZ It is not necessary.
YES It is necessary.
Default value: YES
Possible values
Integer numbers between 0 and 255.
Default value: For MINSOVR (P10) = 50.
For MAXSOVR (P11) = 150.
Possible values
Integer numbers between 0 and 255.
Default value: 5
Possible values
Integer numbers between 0 and 299999.
Default value: 1000
