APPENDIX D

Interfacing the Internal Differential Optical Encoder

Factory Mounted Encoder

Encoders are available in differential configurations. All encoders have an index mark, except the MDrive42AC 400 line count.

Use of the encoder feedback feature of this product requires a controller such as an IMS MicroLYNX or PLC.

The encoder has a 100 kHz maximum output frequency.

The MDriveAC Plus Microstepping are available with an internal differential optical encoder. Available line counts are:

MDrive34AC		MDrive42AC
Line Count	Part Number	Line Count	Part Number
100	EA	100	EA
200	EB	200	EB
250	EC	——	——
