ZSWA.00/01/02 = 0
Pulses inhibited
S2: Ready to power-on
ZSWA.00 = 1, ZSWA.11 =

- Main contactor de-energized (open)
- Wait for power-on or jogging

S5a: Ramp stop
ZSWA.00/01 = 1
ZSWA.11 =
1
ZSWA.02/06 = 0
Ramp-down to n = 0, then
inhibit the pulses
S5b: Fast stop
ZSWA.00/01 = 1, ZSWA.11 = 1
ZSWA.02/06 = 0
Bring the drive to n = 0 along the
fast stopping ramp or torque limit,
then inhibit the pulses
S3: Ready
ZSWA.00/01 = 1, ZSWA.11 = 0
ZSWA.02/06 = 0
