6 Incremental Encoder Input Units
6 - 30 NX-series Position Interface Units User’s Manual (W524)
When you use an NJ/NX-series Controller with the MC Function Module, you must set the Unit as an
encoder axis. Set the axis parameter settings and assign an axis variable from the Sysmac Studio.
Refer to the NJ/NX-series CPU Unit Motion Control User’s Manual (Cat. No. W507) for detailed setting
procedures.
Observe the following precautions when you use an Incremental Encoder Input Unit with the MC Func-
tion Module.
• Connect the Incremental Encoder Input Unit after an EtherCAT Coupler Unit.
• The Unit is treated as an axis (encoder axis) from the user program, so you cannot handle the I/O
data from the Incremental Encoder Input Unit directly. Use motion control instructions and an axis
variable to manipulate this data.
• For an NX-series CPU Unit, you can execute motion control in the primary periodic task and priority-5
periodic task.
• Some functions are fixed and no selections are available. For example, gate control requires that you
always enable the counter. Counter reset and preset operations are calculated in the MC Function
Module and therefore do not change any data in the Incremental Encoder Input Unit.
Yes: Can be used, Partial: Can be used with restrictions, No: Cannot be used
You can control latching for an encoder axis with the following motion control instructions.
