Encoder Inputs
The Communication card features four 4x encoder inputs that can be used to connect to either a single-ended or
differential encoder. Using an encoder allows you to specify input and output delay values in pulse counts instead of real
time units. Refer to Wire Inputs and Outputs on page27 for common wiring configurations.
Note:
l Non-quadrature, single-channel encoders are not supported.
l The frequency of encoder pulses must not exceed 50 kHz.
