Explanation of the Control Bits
Bit 00, OFF 1/ON 1

Bit 00 = "0" leads to the stop and activation of the output relay 1 or 2 if the output frequency is 0 Hz and if
[Relay 123] has been selected in par. 5-40 Function relay.
When bit 00 = "1", the frequency converter is in State 1: "Switching on inhibited".
