The axis in PLC axis mode does not become the external deceleration speed even if the
External deceleration + signal (*+EDT1 to 8) or External deceleration - (*-EDT1 to 8) sig-
nal is turned OFF.
Speed is monitored as NC axis even in PLC axis mode.
Even in PLC axis mode, the absolute value initialization set is performed using Zero
point initialization set mode signal (AZSn) and Zero point initialization set start (ZSTn).
PLC axis signals are used to start the axis or etc. even while the axis in PLC axis mode
is being initialized.
The axis in PLC axis mode does not perform the high-accuracy control.
The axis in PLC axis mode is acceleration/deceleration with constant time (conventional)
method regardless of the setting of parameters "#1200 G0_acc" or "#1201 G1_acc".
The compensation amount set for NC axis is valid even in PLC axis mode.
The axis is stopped with stroke end signal of NC axis even in PLC axis mode. Also, as
it is in NC axis/PLC axis switchover invalid status during stroke end, cancel the alarm
before executing the switching.
If the alarm of stroke end or soft limit occurs for the axis in PLC axis mode, the alarm
(T01 0106) occurs and the cycle start cannot be performed. If the limit alarm occurs for
the axis in PLC axis mode during the cycle start, the alarm (T02 0202) occurs and the
program stops.
This is valid even in PLC axis mode. Also, as it is in NC axis/PLC axis switchover invalid
status during soft limit, cancel the alarm before executing the switching.
The alarm can be canceled by resetting each control mode. However, the soft limit IB
and IIB are canceled with the reset of NC axis regardless of control mode.
If the alarm of soft limit occurs for the axis in PLC axis mode, the alarm (T01 0106) oc-
curs and the cycle start cannot be performed. If the limit alarm occurs for the axis in PLC
axis mode during the cycle start, the alarm (T02 0202) occurs and the program stops.
When the axis is moved from outside of the limit range to within the range in PLC axis
mode, the clamp with the parameter "#2021 out_f" is not performed and it is operated
with the commanded speed.
The signals (fixed/arbitrary assignment) of NC axis are used even in PLC axis mode.
The signals of PLC axis are not used.
The PSW set for NC axis is valid even in PLC axis mode.
The data is read or written by specifying the NC axis No. to the axis No. even in PLC axis
mode. When PLC axis No. is specified, the alarm "Data type illegal" occurs.
This can be executed even in PLC axis mode.
This cannot be executed in PLC axis mode.
This is valid even in PLC axis mode.
These cannot be used for the switching axis. If the parameter was set to use the switch-
ing axis with the function on the left, the alarm (Y05 2187) occurs when NC is turned ON.
The axis in PLC axis mode cannot be specified to the reference axis or superimposed
axis. The operation error (M01 1004) occurs when the superimposition starts.
The reference axis or superimposed axis in superimposition cannot be switched to PLC
axis mode. If NC axis/PLC axis switchover request is turned ON, the operation error
(M01 1250) occurs.
For the part system including the reference axis and superimposed axis, stop all axes
before starting or ending the superimposition. The condition to stop all axes includes the
axis in PLC axis mode.
The axis in PLC axis mode cannot be used with control axis synchronization between
part systems. The operation error (M01 1037) occurs when the synchronization starts.
The reference axis or the synchronized axis in synchronization cannot be switched to
PLC axis mode. If NC axis/PLC axis switchover request is turned ON, the operation error
(M01 1250) occurs.
For the part system including the reference axis and synchronized axis, stop all axes be-
fore starting or ending the synchronization. The condition to stop all axes includes the
axis in PLC axis mode.
