Notes:

  • Digital inputs accept standard signal levels 2.7 - 5.5 VDC.
  • All outputs provide 3.3 V with maximum load of 8 mA.
  • All GPO pins have a 180 Ohm series resistor.

D) PWM can be used with or without direction signal. With PWM setpoint without direction signal 50 % PWM = zero setpoint.

P) Internal 10 kOhm pull-up resistor.

X3 - Additional setpoint and IO connector[edit | edit source]

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.

Notes:

  • Digital inputs accept standard signal levels 2.7 - 5.5 VDC.
  • All GPO pins provide 3.3 V with maximum load of 8 mA.
  • All GPI/O pins have a 180 Ohm series resistor.

A) Setpoint = zero with 50 % input voltage if direction signal is not used.

L) Limit switches are to be wired with NO (normally open) switch to ground. When a limit switch is triggered, movement to the corresponding direction is disabled.

P) Internal 10 kOhm pull-up resistor.

S) Controllable through SimpleMotionV2 bus.
