X1 - Granity and SimpleMotion V2 connector

X2 - Main setpoint connector

Connect X2 only to 3.3V or 5V logic systems.

X2 is main control and setpoint signal port consisting Global Enable input signal, Global Fault output signal, pulse and direction/PWM setpoint inputs, and digital outputs for servo ready signals. X2 is directly wired to conform most common parallel port style pulse & direction CNC controllers.

Notes:

  • All inputs are logic HIGH with input voltage from 2.7 V to 5 V.
  • All outputs source 3.3 V with maximum of 8 mA load.

P) Internal 10 kOhm pull-up resistor.

X3 - Additional setpoint and IO connector

Connect X3 only to 3.3V or 5V logic systems.

X3 is a second control and setpoint signal port addition to X2. X3 consists of analog setpoint signal inputs and additional digital I/O.
