Axis parameters
TCOMPLIM (P83)
This parameter limits the maximum compensation applied by the Tandem axis. This limit is also
applied to the integral.
This parameter refers to the master axis. It is defined as percentage of the maximum speed of the
master motor. If programmed with a "0" value, the Tandem control output will be zero, which involves
disabling the Tandem.
ADIFEED (P84)
Maximum feedrate allowed, due to the additive handwheel.
FRAPIDEN (P85)
Maximum axis feedrate when activating the EXRAPID mark and when pressing the rapid key in
execution or in simulation with motion.
If set to 0, it assumes the feedrate set by parameter G00FEED. If it is set with a value higher than
G00FEED, the feedrate will be limited to G00FEED.
This limit does not affect the rapid jog which will still have the value of parameter G00FEED.
PITCHB (P86)
Leadscrew pitch. This parameter must be set when using SERCOS, CAN or analog servo drives.
Depending on the type of servo drives, axis parameter PITCHB (P86) must be set as follows:
Analog servo drives:
When using analog servo drives, if axis parameter NPULSES (P8) =0, it indicates that it is a linear
encoder and axis machine parameter PITCH (P7) indicates the pitch of the linear encoder.
If axis parameter NPULSES (P8) is other than 0, it indicates that it is an encoder and axis machine
parameter PITCHB (P86) indicates the pitch of the leadscrew.
SERCOS digital servo drives
Axis machine parameter PITCHB (P86) indicates the leadscrew pitch and it is written at the drive.
If axis machine parameters PITCHB (P86)=0, INPREV (P87)=0 and OUTPREV (P88)=0, the
leadscrew pitch is read from the drive.
Digital CAN servo
Axis machine parameter PITCHB (P86) sets the leadscrew pitch.
Possible values
Between 0 and 100%.
Default value: 0 (the Tandem axis is disabled).
Possible values
Between 0 and 99999.9999 degrees/min or mm/min.
Between 0 inches/min and 3937.00787 inches/min.
Default value: 1000
Possible values
Between 0 and 199999.9999 degrees/min or mm/min.
Between 0 and 7874.01574 inches/min.
Default value: 0
When using CAN servo, if both parameters NPULSES and PITCHB are set to ·0·, the CNC will assume
the equivalent values of the drive.
