Note:
S The power switched via these outputs is supplied via terminals P24/M24 (X431). This must be taken into account
when dimensioning the external supply.
S The digital outputs only ”function” if there is an external supply (+24 V/0 V at terminals P24/M24).
1) I: Input; DO: Digital output, DI: Digital input, AO: Analog output; AI: Analog input; S: Supply
2) Can be freely parameterized. All of the digital inputs are de--bounced per software. When detecting the signal
a delay time of between 1 and 2 interpolation clock cycles (P1010) is therefore incurred.
3) I0.x is internally hard--wired to the position sensing and acts there with almost no delay.
4) Can be freely par am eter ized. The digital outputs ar e updat ed in the interpolation clock cycle (P1010). A har dware--
related delay time of approx. 200 µs must be added.
5)
The permissible voltage range for the common mode component of the individual encoder signals (A+. A--. B+, B--, C+,
C--, D+, D--, R+, R--) is 1.5...3.5 V.
