0 OFF1
Shutdown, deceleration along RFG ramp, pulse disable when f < f
min
.
0
1 ON
Sets the inverter to the "Ready to run" state, direction of rotation must
be defined via bit 11.
P0840 = 2090:0 P0840 = 2090:0
0 Coast Stop (OFF2)

P0852 = 2090:3 P0852 = 2090:3
0 Reset Ramp Generator
Output of RFG is set to 0 (fastest possible braking operation), inverter
remains in the ON state.
