Square Wave Encoder (Auxiliary)[-EB1/-EB2]

The drive accepts RS-422 square wave encoder signals. The drive will generate a feedback fault if it detects an invalid signal state caused by an open or shorted signal connection. Use twisted-pair wiring for the highest performance and noise immunity.

Specification

Value

Encoder Frequency 10 MHz maximum (25 ns minimum edge separation)
x4 Quadrature Decoding 40 million counts/sec

IMPORTANT: -EB2 Aux Encoder connector includes 5 V and GND pins that you can use to power the auxiliary encoder. For -EB1, you should use the +5 V and GND pins that are accessible on the axis feedback connector(s).
