Switch-on, shutdown, enabling

9.3.1 OFF2 (voltage disconnection) - control word 1, bit 1
The OFF2 signal is low active (log."0" state = voltage disconnection).
The following operating modes are possible:
P648 = 9:
P648 ≠ 9:
Sequence of operations for "Disconnect voltage":
1. Input "Disconnect voltage" command
2. Disable ramp-function generator, n and I controllers
3. I = 0 is applied
set
4. The pulses are disabled when I = 0
5. Output signal "Close operating brake" (binector B0250 = 0, when P080 = 2)
6. Converter reaches operating state o10.0 or higher
7. An "older" actual field current value (K0265) is input as the field current setpoint upper limit
(function is "released" in operating states of ≤o5)
8. The "Line contactor closed" relay drops out
9. Drive coasts to a standstill (or is braked by the operating brake)
10. Parameterizable delay time (P258) runs down
11. The field is reduced to a parameterizable value (P257)
12. When n < n
(binector B0250 = 0, when P080 = 1)
9.3.2 OFF3 (Fast stop) - control word 1, bit 2
The OFF3 signal is LOW active (log."0" state = fast stop).
The following operating modes are possible:
P648 = 9:
P648 ≠ 9:
Sequence of operations for "Fast stop":
1. Input "Fast stop" command (e.g. binary input wired up to "Fast stop")
2. Ramp-function generator is disabled
3. Enter n
set
4. up to SW 1.84:
from SW 1.90:
5. Wait until n < n
6. Output signal "Close operating or holding brake" (binector B0250 = 0)
7. Wait for brake closing time (P088) to run down
8. Enter I
set
9. Ramp-function generator and n controller are disabled
10. The pulses are disabled when I = 0
11. The "Line contactor closed" relay drops out
12. Converter reaches operating state o9.0 or higher
13. Delay time for field current reduction (P258) runs down
14. The field is reduced to a parameterizable value in P257

SIMOREG DC Master Operating Instructions
The control bits in control word 1 are input bit-serially. OFF2 is generated from the AND
operation between the binectors selected with P655, P656 and P657 (see Section 8,
Sheet G180).
The connector selected via P648 is used as control word 1. Bit 1 of this word then
controls the OFF2 function.
(P370, P371) has been reached, the "Close holding brake" signal is output
min
The control bits in control word 1 are input bit-serially. OFF3 is generated from the AND
operation between the binectors selected with P658, P659 and P660 (see Section 8,
Sheet G180).
The connector selected via P648 is used as control word 1. Bit 2 of this word then
controls the OFF3 function.
