Hello.
I am planning to use Technology object - Axis.
Can I connect "hw limit switch" and "input homing switch" to the same hardware highspeed input?
I have 1212C plc and 8 highspeed inputs only, but 3 step motors need to connect.  3 switches are for each motor = 9 inputs.

Will Homing operation (MC_Home) work normal in mode 3 (active)?

Hello,

configuration is possible.

It is necessary to deactivate HW-Limitswitch, when using input for Homing.

Thank you,

but the hardware switch won't work with this variant? Or when the motor hits the reference switch, will the motor stop (normal mode, no Homing)?

Can I activate/deactivate HW-Limit switch in working program, not in axis configuration?

Hello,

it is possible to activate/deactivate via variable.

<axisname>.PositionLimits_HW.<variablename>

Chapter 12.9.12

PositionLimits_HW.Active
