Siemens SINAMICS G120 List Manual page 161

For drives with closed-loop torque control (p1300 = 22, 23), the following applies:
- BI: p0840 = 0 signal: immediate pulse suppression
For drives with closed-loop torque control (activated using p1501), the following applies:
- BI: p0840 = 0 signal: No dedicated braking response, but pulse cancelation when standstill is detected (p1226,
p1227)
For drives with closed-loop speed/torque control, the following applies:
- BI: p0840 = 0/1 signal: ON (pulses can be enabled)
For active infeeds (Active Line Module and Smart Line Module) the following applies:
- BI: p0840 = 0 signal: OFF1 (reduce Vdc along the ramp, then pulse suppression and precharging contactor/line
contactor open)
- BI: p0840 = 0/1 signal: ON (precharging contactor/line contactor close, pulses can be enabled)
For passive infeeds (Basic Line Module) the following applies:
- BI: p0840 = 0 signal: OFF1 (precharging contactor/line contactor open)
- BI: p0840 = 0/1 signal: ON (precharging contactor/line contactor close)
r0863.1 of a drive can also be selected as signal source.

Description: Sets the signal source for the command "ON/OFF (OFF1)".
For the PROFIdrive profile, this command corresponds to control word 1 bit 0 (STW1.0).
Recommendation: When the setting for this binector input is changed, the motor can only be switched on by means of an appropriate
signal change of the source.
Dependency: Refer to: p1055, p1056
Caution: When "master control from PC" is activated, this binector input is ineffective.
Notice: For binector input p0840 = 0 signal, the motor can be moved, jogging using binector input p1055 or p1056.
The command "ON/OFF (OFF1)" can be issued using binector input p0840 or p1055/p1056.
For binector input p0840 = 0 signal, the switching-on inhibited is acknowledged.
Only the signal source that originally switched on can also switch off again.
The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
Note: For drives with closed-loop speed control (p1300 = 20, 21), the following applies:
- BI: p0840 = 0 signal: OFF1 (braking with the ramp-function generator, then pulse suppression)
For drives with closed-loop torque control (p1300 = 22, 23), the following applies:
- BI: p0840 = 0 signal: immediate pulse suppression
For drives with closed-loop torque control (activated using p1501), the following applies:
- BI: p0840 = 0 signal: No dedicated braking response, but pulse cancelation when standstill is detected (p1226,
p1227)
For drives with closed-loop speed/torque control, the following applies:
- BI: p0840 = 0/1 signal: ON (pulses can be enabled)
For active infeeds (Active Line Module and Smart Line Module) the following applies:
- BI: p0840 = 0 signal: OFF1 (reduce Vdc along the ramp, then pulse suppression and precharging contactor/line
contactor open)
- BI: p0840 = 0/1 signal: ON (precharging contactor/line contactor close, pulses can be enabled)
For passive infeeds (Basic Line Module) the following applies:
- BI: p0840 = 0 signal: OFF1 (precharging contactor/line contactor open)
- BI: p0840 = 0/1 signal: ON (precharging contactor/line contactor close)
r0863.1 of a drive can also be selected as signal source.
