Get Started
After powering up the inverter and Profibus master, connection will be established. Expect to
see bit 6 (Switching on inhibited) set in ZSW1. Below is a simplified state diagram, dependent
on control word 1 (STW1).

Fault reset
Both No Coast Stop and No Quick Stop need to be set to reset the Switching On Inhibited bit
in ZSW1. To do this set bits 1 and 2 in STW1, that is bit 1 and 2 in QW0.
