MACHINE PARAMETERS.

General machine parameters.
• When the axes are rotary, both axes must be of the same type (same AXISMODE and
SHORTESTWAY parameters for both axes).
• The fast and slow home search speeds (parameters REFFEED1 and REFFEED2) must
be the same for both axes.
TANDEM n
Configuration of each tandem pair.
This parameter shows the parameter table to define the tandem pairs of the system. Each
tandem pair has the following machine parameters to configure it.
MASTERAXIS
Tandem pair. Master or main axis/spindle.
Possible values: Any axis defined in the parameter AXISNAME or spindle defined in SPDLNAME.
Associated variable: (V.)MPG.TMASTERAXIS[nb]
Parameter included in the TANDEM table.
This parameter sets which is the master axis or spindle of the tandem pair. The master motor
of the tandem, besides generating torque, it is in charge of positioning.
The CNC closes the position loop only with the position of the master axis of the tandem.
The velocity command of the master axis/spindle of the tandem is also sent to the slave
axis/spindle of the tandem closing the velocity loop. The tandem control changes the velocity
command of the master axis/spindle and that of the slave axis/spindle according to the torque
distribution and the selected preload.
SLAVEAXIS
Tandem pair. Slave axis/spindle.
Possible values: Any axis defined in the parameter AXISNAME or spindle defined in SPDLNAME.
Associated variable: (V.)MPG.TSLAVEAXIS[nb]
Parameter included in the TANDEM table.
This parameter sets which is the slave axis or spindle of the tandem pair. The slave motor
only provides torque. The CNC closes the position loop only with the position of the master
axis of the tandem.
TORQDIST
Tandem pair. Torque distribution.
Possible values: from 1 to 99%.
Default value: 50 %.
Associated variable: (V.)MPG.TORQDIST[nb]
Parameter included in the TANDEM table.
This parameter sets the torque percentage supplied by each motor to obtain the total
necessary torque in the tandem. The parameter indicates the percentage to be provided by
the master motor. The difference between the value of this parameter and 100% is the
percentage applied to the slave motor.
If the motors are identical and they're both supposed to output the same torque, this
parameter should be set to 50%.
TANDEM
MASTERAXIS Tandem pair. Master or main axis/spindle.
SLAVEAXIS Tandem pair. Slave axis/spindle.
TORQDIST Tandem pair. Torque distribution.
PRELOAD Tandem pair. Preload between both motors.
PRELFITI Tandem pair. Filter time to apply the preload.
TPROGAIN Tandem pair. Proportional gain (Kp) for the tandem.
TINTIME Tandem pair. Integral gain (Ki) for the tandem.
TCOMPLIM Tandem pair. Compensation limit.
