Motor Position
Motor positions can be read usingthe PX/PY command which returns the pulse position of the specified axis.
Encoder positions can be read using EX/EY command which returns the encoder position of the specified axis.
To manually set/get the pulse position of an individual axis, use the PX/PY command.
Note that setting the pulse position is not allowed if StepNLoop isenabled.
To manually set/get the encoder position of an individual axis, use the EX/EY command.
Polarity
The polarity settings of the PMX-2EX-SA can also be read or set at any time using the POLX/POLY
commands. The following is the bit representation of the polarity:

Table 23 Polarity
†Used for error handling within standalone operation. If this bit is on, the line that is executed after SUB31 is
called will be line 0. Otherwise, it will be the line that caused the error.
Limits
If positive limit switch is triggered while moving in positive direction, the motor will immediately stop and the
motor status bit for positive limit error is set. The same is for the negative limit while moving in the negative
direction. To read the limit switch input status, use the MSTX/MSTY command.
Once the limit or alarm error is set, use the CLR[axis] command to clear the error.
The limit error states can be ignored by setting IERR=1. In this case, the motor will still stop when the
appropriate switch is triggered; however, it will not enter an error state.
