Caution
CAUTION
When a multiaxis amplifier is used, the motor
cannot be disconnected from the amplifier. When
the motor needs to be disconnected from the
amplifier for replacement of the rotary table or other
reasons, a 1-axis amplifier must be used.
Note
NOTE
1 Controlled axis detach signals DTCH1 <G124#0>,
DTCH2 <G124#1>, DTCH3 <G124#2>, 0 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 RMB
(No. 1005#7) must be set, indicating the axes are
detachable.
3 Setting parameter RMV (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
PS0224 to be output.
If an axis for which an absolute position detector is
used (bit 5 (APC) of parameter No. 1815 is set to 1)
is released from control, the correspondence
between the machine position and reference
position is lost. Consequently, bit 4 (APZ) of
parameter No. 1815 indicating that the
correspondence is established is set to 0, resulting
in alarm DS0300. After an axis is released from
control, perform reference position return to bring
the machine position into correspondence with the
reference position.
