SINAMICS G120 / Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
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).
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 switch-on inhibit is acknowledged.
Only the signal source that originally powered up can also power down 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), the following applies:
- BI: p0840 = 0 signal: OFF1 (braking with the ramp-function generator, then pulse suppression and switch-on
inhibit)
For drives with closed-loop torque control (p1300 = 22), the following applies:
- BI: p0840 = 0 signal: immediate pulse cancellation
For drives with closed-loop torque control (activated using p1501), the following applies:
- BI: p0840 = 0 signal: No dedicated braking response, but pulse suppression 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)
Description: Sets the first signal source for the command "No coast down/coast down (OFF2)".
The following signals are AND'ed:
- BI: p0844 "No coast-down / coast-down (OFF2) signal source 1"
- BI: p0845 "No coast-down / coast-down (OFF2) signal source 2"
For the PROFIdrive profile, the result of the AND logic operation corresponds to control word 1 bit 1 (STW1.1).
BI: p0844 = 0 signal or BI: p0845 = 0 signal
- OFF2 (immediate pulse suppression and switch on inhibit)
BI: p0844 = 1 signal and BI: p0845 = 1 signal
- No OFF2 (enable is possible)
Caution: When "master control from PC" is activated, this binector input is ineffective.
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
