YASKAWA TM.A1000SW.117 Motion Control Custom Software Supplement 25
Absolute Incremental Encoder
For use with a TR-electronic, series CE-65 serial (ISI) encoder. The drive must read the actual position of the absolute
incremental encoder upon power up. This process usually is completed within a few seconds. As an option, the encoder
can be monitored and configured directly using a PC, an RS-232 to RS-485 converter, and the TR Electronic EPROGW32
program.

Note: Change the terminal AM gain (H4-05) from the default setting of 50.0% to 200.0% when using terminal AM for the Serial
Encoder Position Request (H4-04 = 710). Otherwise, the serial encoder read request will fail and a SENCF (Serial Encoder
Fault) will occur.
