Basic Features of the PTO Module FM562

Digital inputs

4 inputs (2 inputs per axis)

  • Input 0, Input 2: Enable input used for limit switches and enable signal (3 signals in 1 chain)

  • Input 1, Input 3: Stop/Registration input used as interrupt input
  • Stop: emergency stop and give the actual position information, the deceleration value can be set via the Function Block which is provided by the library.
  • Registration: give the actual position information, number can be viewed via the Function Block which is provided by the library, the registration input can be used for homing.
PTO outputs

PTO output mode can be configured by parameters.

  • 2-axis control in 1 module
  • PTO output type: RS-422 differential output
  • PTO frequency: 0..250 kHz
  • Configurable PTO output mode: Pulse + Direction / CW + CCW
  • CW/CCW (clockwise/counterclockwise): pulse string is set out on 1 of the 2 differential channels according to motor rotation direction. The output channel is defined by a Function Block.

Pulse+ / Pulse- (CW/CCW)

PTO Output 0 (CW)
