PMC Axis Control
2004.10.7
Signal Detail (PMC axis control)
(1) Controlled axis selection signals EAX1 to EAX32 <G0136>
[Classification] Input signal, axis-by-axis signal
[Function] Exercises PMC axis control.
[Function] When the signal is set to "1", PMC axis control becomes valid.
When the signal is set to "0", PMC axis control becomes invalid. Changing the setting of
the control axis selection signal is possible only when control axis selection status signal
*EAXSL is set to "0". Changing the setting when *EAXSL is set to "1" results in the issue of
an alarm PS0139. Alarm signal EIALg is set to "1". When the parameter NCC (No. 8001#5),
is set to "0", a command issued from the CNC is executed while the control axis selection
signal is set to "1" and signal *EAXSL is set to "0". When the parameter is set to "1", the
same attempt results in the issue of an alarm PS0139.
If the control axis selection signal is set to "1" while the CNC is currently executing a
command, an alarm is generated.
While *EAXSL is set to "0", the status of alarm signal EIALg does not change to 1 when the
control axis selection signal is set to 1 and an alarm PS0139 is generated. In this case, the
axis can be controlled from the PMC, even when the CNC is in the alarm status.
NOTE
After setting control axis selection signals EAX1 to EAX8 to 1, it takes
at least 8 msec before the PMC can issue commands to the CNC.
(2) Axis control command signals
EC0g to EC6g<G143.0 to .6, G155.0 to .6, G167.0 to .6, G179.0 to .6>
[Classification] Input signal, group-by-group signal
[Function] One of the axis control block data signals
[Operation] Specifies a type of command with 7 bits.
For the meaning of each command, see Table 1.1.1 (g) Command list.
(3) Controlled axis feed signals
EIF0g to EIF15g <G144 to 145, G156 to 157, G168 to 169, G180 to 181>
[Classification] Input signal, Group-by-group signal
[Function] One of the axis control block data signals
[Operation] Two-byte command interface area
Each command has a different function. For details, see Table 1.1.1 (g) Command list.
