Commissioning steps:
1. Connect the line contactor control contact to DI/DO 8.
2. Parameterize DI/DO 8 as output (p0728.8 = 1).
3. Assign parameter p0738 the control signal for the line contactor r0863.1.
4. Connect the line contactor feedback contact to DI/DO 9.
5. Assign parameter p0860 an inverted input signal r0723.9.
6. Enter the monitoring time for the line contactor (100 ms) in p0861.
Line contactor behavior for Safe Torque Off (STO)
If the Safety Integrated function initiates an STO, the line contactor opens automatically.
If, however, the line contactor should remain closed when the STO is initiated, make the
following setting:
1. Set p0869 = 1.
2. Use p0867 to specify how long the line contactor should remain closed after initiating the
