Bit Meaning Comments P No.
0 0 = OFF1 The motor brakes with the ramp-down time p1121 of the ramp-
function generator. The converter switches o󹪜 the motor at
standstill.
p0840[0] =
r2090.0
0 → 1 = ON The converter goes into the "ready" state. If, in addition,
bit 3 = 1, the converter switches on the motor.
1 0 = OFF2 Switch o󹪜 motor immediately, then the motor coasts to a
standstill.
p0844[0] =
r2090.1
1 = No OFF2 It is possible to switch on the motor (ON command).
2 0 = Quick stop (OFF3) Quick stop: the motor brakes with the OFF3 ramp-down time
p1135 down to standstill.
p0848[0] =
r2090.2
1 = No quick stop (OFF3) It is possible to switch on the motor (ON command).
3 0 = Inhibit operation Immediately switch-o󹪜 motor (cancel pulses). p0852[0] =
r2090.3
1 = Enable operation Switch-on motor (pulses can be enabled).
4 0 = Reject traversing job Axis brakes down to standstill with the maximum deceleration.
Converter rejects the actual traversing block.
p2641 =
r2090.4
1 = Do not reject traversing task Axis can be started or travel to position setpoint.
5 0 = Intermediate stop Axis brakes down to standstill with the speci󹪝ed deceleration
override. Converter remains in the actual traversing block.
p2640 =
r2090.5
1 = No intermediate stop Axis can be started or continue to travel to position setpoint.
6 0 → 1: Activate traversing job The converter starts axis travel to the setpoint position. p2631 =
r2090.6
0 → 1: Setpoint transfer MDI p2650 =
r2090.6
7 0 → 1: = Acknowledge faults Acknowledge fault in the converter. If the ON command is still
active, the converter switches to "closing lockout" state.
p2103[0] =
r2090.7
8 1 = jogging bit 0 Jogging 1 p2589 =
r2090.8
9 1 = jogging bit 1 Jogging 2 p2590 =
r2090.9
10 0 = No control via PLC Converter ignores the process data from the 󹪝eldbus. p0854[0] =
r2090.10
1 = Control via PLC Control via 󹪝eldbus, converter accepts the process data from
the 󹪝eldbus.
11 0 = Stop referencing --- p2595 =
r2090.11
1 = Start referencing The converter does not start referencing.
12 Reserved
13 0 → 1: External block change The axis goes to the next traversing block. p2633 =
r2090.13
14, 15 Reserved
