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:
