Features
The EtherCAT slave ECAT-2093 is an incremental encoder counter which provides three independent high-speed counter channels. It reads the pulse train generated by an incremental encoder and can be used in positioning feedback applications. Each channel has two counter inputs. The inputs can either be single-ended or differential signals. Three counting modes are supported: clockwise/counterclockwise, pulse/direction and quadrant counting mode. The hardware index latch function allows the latching of encoder position. Low pass filter functions for filtering out electrical noises are provided.

Applications
Digital Input Channel
The ECAT-2093 can accept encoder inputs from either differential or single-ended signals. By default it is set to support differential encoder signals as they are preferred due to their excellent noise immunity. For single-ended encoder connection the ECAT-2093 provides an internal 1k Ohm resistor for each signal input. The internal resistor can be selected via jumper setting.
Counting Modes
The ECAT-2093 encoder counter supports three modes:
- Pulse/Direction counting mode
- Clockwise/Counterclockwise mode
- Quadrant counting mode
