1. AXIS CONTROL
16
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 valu e of the parameter, due
to the nature of multiaxis amplifier.
CAUTION
When a 2--axis or 3--axis amplifier is used, releasing only
one axis from control results in the output of servo alarm401
(V ready off). Use 1--axis amplifiers for those axes to be
released from control, e.g., by replacing the rotary table.
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).
