General Specifications and ...
Input resistance, R
Pulse input accuracy (0.1-1 kHz)
Encoder input accuracy (1-11 kHz)
The pulse and encoder inputs (terminals 29, 32, 33) are galvanically isolated from the supply voltage (PELV) and other high-
voltage terminals.
1) Pulse inputs are 29 and 33
2) Encoder inputs: 32 = A, and 33 = B
