I am trying to Program a P66 Inverter without using Automation Studio and using the digital inputs. I am able to get it to run normally but as soon as a enable SAF and SAr. I cant get the drive to run. Is there another parameter I need to set in order to get this to work?
TIA
Hi Community, can anyone help Kendal?
The assignments defined in SAF and SAR are stop switches.
Hence, if the assigned event in SAF is triggered, driving the motor in Forward direction is inhibited.
Hence, if the assigned event in SAR is triggered, driving the motor in Reward (backward) direction is inhibited.

you also have to set ‘SAL’ correctly which is ‘active low’ by default.
So if you’ve no voltage at the inputs the stop function is permanently active.

The detailed behavior of the end switches is defined by MSTP and PRST
MSTP: what happens to the internal BOOL value if the end switch is overshoot?
PRST: what has higher priority - a set end switch or a restart command?
