1. AXIS CONTROL
166
8. An axis does not move to a specified position after synchronous or
composite control switching.
(1)A move command was issued within two blocks after synchronous
or composite control.
The coordinate system in the CNC must be re--set at synchronous
or composite control switching. No move command can be issued
to an axis subjected to synchronous or composite control during
automatic operation within two (or three for tool--tip radius
compensation) blocks (including the current one) after
synchronous or composite control switching. However, this
restriction does not apply when the current block is an M code that
does not buffer the next block or when the target axis is a
synchronous master axis.
9. Synchronous, composite, or superimposed control was terminated
when the G0128, G0138, G0190, G1128, G1138, or G1190 did not
drop.
Synchronous, composite, or superimposed control is terminated
automatically, if one of the following conditions occurs in either
path.
S Emergency stop
S Reset
S Servo alarm
S P/S000 alarm
S Alarm related to synchronous, composite, or superimposed
control
In addition, synchronous, composite, or superimposed control is
terminated for all axes, if one of the following conditions occurs for
any axis under synchronous, composite, or superimposed control.
S Servo--off
S Overtravel
