[Operation] While the signal is 1, PMC axis control is enabled, and commands
issued by the CNC are ignored. While the signal is 0, on the other hand,
PMC axis control is disabled.
(1) Switching from CNC-controlled axis to PMC-controlled axis
(from 0 to 1)
When a move command in automatic operation mode is specified
for a PMC-controlled axis, setting bit 5 (NPA) of parameter No.
2405 to 1 can invalidate the input command.
If this parameter is set to 0, alarm "PS450 IN PMC AXIS MODE"
is issued. When a movement is already being performed in
automatic operation or manual operation mode, the command
pulses are invalidated.
(2) When a CNC command is executed after switching from a PMC-
controlled axis to CNC-controlled axis (from 1 to 0)
Automatic operation: Enabled from the first buffering block
Manual operation: After switching, perform mode selection
again.
NOTE
Before changing the logical level of a PMC axis
control signal, confirm that no movement is being
made along the corresponding axis.
