Parameters
Parameter list
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 cancellation and power-on inhibit)
For drives with closed-loop torque control (p1300 = 22, 23), the following applies:
Bit 0 = 0: Immediate pulse cancellation
For drives with closed-loop torque control (activated using p1501), the following applies:
Bit 0 = 0: No dedicated braking response, but pulse cancellation 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 infeed units, the following applies:
Bit 0 = 0: OFF1 (reduce Vdc along the ramp, then pulse cancellation and pre-charging contactor/line contactor
open)
Bit 0 = 0/1: ON (pre-charging contactor/line contactor closed, pulses can be enabled)
For passive infeed units (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.
p0844[0...n] BI: 1. OFF2 / 1. OFF2
VECTOR Can be changed: T
Data type: Unsigned32
P-Group: Commands
Min
-
Description: Sets the signal source for the 1st OC/OFF2.
The AND logic operation of the 1st OC/OFF2 and 2nd OC/OFF2 results in control word 1, bit 1 (OC/OFF2).
Note: For drives, the following applies:
Bit 1 = 0: OFF2 (immediate pulse cancellation and power-on inhibit)
Bit 1 = 1: No OFF2 (enable is possible)
For infeed units, the following applies:
Bit 1 = 0: OFF2 (immediate pulse cancellation for active infeed units, pre-charging contactor/line contactor open
and power-on inhibit)
Bit 1 = 1: No OFF2 (enable is possible)
OC: Operating condition
p0845[0...n] BI: 2. OFF2 / 2. OFF2
VECTOR Can be changed: T
Data type: Unsigned32

-
Description: Sets the signal source for the 2nd OC/OFF2.
The AND logic operation of the 1st OC/OFF2 and 2nd OC/OFF2 results in control word 1, bit 1 (OC/OFF2).
Note: For drives, the following applies:
Bit 1 = 0: OFF2 (immediate pulse cancellation and power-on inhibit)
Bit 1 = 1: No OFF2 (enable is possible)
For infeed units, the following applies:
Bit 1 = 0: OFF2 (immediate pulse cancellation for active infeed units, pre-charging contactor/line contactor open
and power-on inhibit)
Bit 1 = 1: No OFF2 (enable is possible)
OC: Operating condition
