MCCx When an axis is released from control, control for the MCC signal for
the corresponding servo amplifier is
0 : Disabled
1 : Enabled
NOTE
If the servo motor for an axis is connected to a 2-axis or
other multiaxis amplifier, releasing the axis from control
causes servo alarm 401 (V ready off) to be output. This
alarm can be disabled by this parameter. When the servo
motor is disconnected from the CNC, however, servo
alarm 401 is output, regardless of the value of the
parameter, due to the nature of multiaxis amplifier.
Caution
CAUTION
When a 2-axis or 3-axis amplifier is used, releasing only
one axis from control results in the output of servo alarm
401 (V ready off). Use 1-axis amplifiers for those axes to
be released from control, e.g., by replacing the rotary
table.
Note
NOTE
1 Controlled axis detach signals DTCH1 <G124#0>, DTCH2
<G124#1>, DTCH3 <G124#2>, … can be changed from 1
to 0 or from 0 to 1 when the power is first turned on or
when no movement is being executed along the
corresponding axis. If these signals are changed from 0 to
1 when the tool is moving along the corresponding axis,
the axis is released from control upon completion of the
movement.
2 For these signals to be attached, parameter No. 1005#7
must be set, indicating the axes are detachable.
3 Setting parameter No. 0012#7 from the MDI panel
detaches the axes in the same way as these signals.
4 Those axes that are released from control lose their
reference positions. Reference position return must,
therefore, be performed for the axes prior to executing
move commands for the axes. Specifying a move
command before reference position return has been
performed causes alarm 224 to be output (the alarm can
be disabled by setting bit 0 (ZRNx) of parameter 1005).
