Tandem Function

The tandem function outputs the same movement command of a specified axis (master axis) to another axis (slave axis)
during G-code control. The axes used for tandem function are set in [Motion Control Parameter][G-code Control
Parameter][G-code Control Axis Parameter]"Tandem Function""Master Control Axis Name". The tandem function
enable information can be checked with "[Md.3153] Tandem function enabled information (D54755+32sn)".
Cautions
• The axis address set to the slave axis cannot be specified in the G-code program. When the axis address set to the slave
axis is specified, the command is ignored.
• Contents for the status and monitor devices of the slave control axis when enabled/disabled are shown below.
Device
[St.3076] Smoothing zero (D54448.0+2sn)
[Md.3153] Tandem function enabled information (D54755+32sn)
[Md.3147] Machine position (D54768+32sn, D54769+32sn)
[Md.3148] Machine target position (D54770+32sn, D54771+32sn)
[Md.3149] Relative position (D54772+32sn, D54773+32sn)
[Md.3150] Relative target position (D54774+32sn, D54775+32sn)
[Md.3152] Program target position (D54778+32sn, D54779+32sn)
• When using tandem function, before turning ON G-code control request, match the reference positions of the master
control axis and slave control axis.
• For G-code control axis parameters "fast forward speed", "cutting feed clamp speed", "G0 time constant (linear)", and "G1
time constant (linear)", the values set to the slave control axis No. are ignored and the values set to the master control axis
No. are used.
• Note that the stored stroke limit operation for slave control axes is as follows.
