Objectives
Overview
- 2 Encoder inputs
- Configurable to accept all known variations of Synchronous Serial Interface protocols
- Fully configurable SSI communication parameters per channel
- Easy wiring
Please note that the data transfer from the SSI encoder with the NJ CPU is not synchronised with the EtherCAT cycle.
Version Support
The CJ1W-CTS21-E unit is supported by NJ-series CPU firmware version 1.02 and higher as well as Sysmac Studio version 1.02 and higher.
Summary
In general, the CJ1W-CTS21 unit will function the same on an NJ-series controller compared to the CJ-series PLC. However, instead of memory allocation based on Machine Number settings for configuration and operation, the NJ-series uses Device Variables for these purposes. See the attachment "CJ1W-CTS21-E for NJ InstrSheet.pdf" for more information.
