SINAMICS S List Manual (LH1), 07/2007
Description: Sets the delay time for motor changeover.
The delay time is taken into account in the following cases:
- for feedback signal, previous contactor "Open". The new motor contactor is controlled (energized) after the delay
time has expired.
- for the feedback signal, new motor contactor "Closed". The pulses are enabled after the delay time has expired.
Description: Sets the signal source for control word 1 bit 0 (ON/OFF1).
Recommend.: When the signal source is set, this does not trigger a response - but only a signal change of the source.
Dependency: Refer to: p1055, p1056
Notice: For BI: p0840 = 0 signal, the motor can be moved, jogging using BI: p1055 or BI: p1056.
The command "ON/OFF1" can be issued using BI: p0840 or using BI: p1055/p1056.
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, 21), the following applies:
Bit 0 = 0: OFF1 (braking with the ramp-function generator, then pulse cancelation and power-on inhibit)
For drives with closed-loop torque control (p1300 = 22, 23), the following applies:
Bit 0 = 0: Immediate pulse cancelation
For drives with closed-loop torque control (activated using p1501), the following applies:
Bit 0 = 0: No dedicated braking response, but pulse cancelation when standstill is detected (p1226, p1227)
For drives with closed-loop speed/torque control, the following applies:
Bit 0 = 0/1: ON (pulses can be enabled)
For active infeeds (Active Line Module and Smart Line Module) the following applies:
Bit 0 = 0: OFF1 (reduce Vdc along the ramp, then pulse cancelation and pre-charging contactor/line contactor
open)
Bit 0 = 0/1: ON (pre-charging contactor/line contactor closed, pulses can be enabled)
For passive infeeds (Basic Line Module) the following applies:
Bit 0 = 0: OFF1 (pre-charging contactor/line contactor open)
Bit 0 = 0/1: ON (pre-charging contactor/line contactor closed)
r0863.1 of a drive can also be selected as signal source.
