Bit Meaning Explanation BACNet Signal inter‐
connection in
the inverter
2 0 = Quick stop (OFF3) Quick stop: The motor brakes with the
OFF3 ramp-down time p1135 down to
standstill.
BV28 p0848[0] =
r2090.2
1 = No quick stop (OFF3) The motor can be switched on (ON
command).
3 0 = Inhibit operation Immediately switch-off motor (cancel
pulses).
BV26 p0852[0] =
r2090.3
1 = Enable operation Switch-on motor (pulses can be ena‐
bled).
4 0 = Disable RFG The inverter immediately sets its ramp-
function generator output to 0.
BV26 p1140[0] =
r2090.4
1 = Do not disable RFG The ramp-function generator can be
enabled.
5 0 = Stop RFG The output of the ramp-function gener‐
ator stops at the actual value.
BV26 p1141[0] =
r2090.5
1 = Enable RFG The output of the ramp-function gener‐
ator follows the setpoint.
6 0 = Inhibit setpoint The inverter brakes the motor with the
ramp-down time p1121 of the ramp-
function generator.
BV26 p1142[0] =
r2090.6
1 = Enable setpoint Motor accelerates with the ramp-up
time p1120 to the setpoint.
7 0 → 1 = Acknowledge
faults
Acknowledge fault. If the ON com‐
mand is still active, the inverter
switches to "closing lockout" state.
BV22 p2103[0] =
r2090.7
8, 9 Reserved N/A ---
10 0 = No control via PLC Inverter ignores the process data from
the fieldbus.
BV93 p0854[0] =
r2090.10
1 = Control via PLC Control via fieldbus, inverter accepts
the process data from the fieldbus.
11 1 = Direction reversal Invert setpoint in the inverter. BV21 p1113[0] =
r2090.11
12 Reserved N/A ---
13 1 = MOP up Increase the setpoint saved in the mo‐
torized potentiometer.
N/A p1035[0] =
r2090.13
14 1 = MOP down Reduce the setpoint saved in the mo‐
torized potentiometer.
N/A p1036[0] =
r2090.14
15 Reserved N/A ---
