Switch-On / Shutdown (On / Off) Terminal 37 - Control Word 1, Bit 0 - Siemens SIMOREG DC Master 6RA7028-6DS22 Operating Instructions Manual

02.00
Sequence of operations for cancellation of "Fast stop":
1. Stop applying "Fast stop" command
2. Enter "Standstill" command (e.g. via "Switch-on/shutdown" terminal)
3. Converter exits operating state o8

− The "Fast stop" command need only be applied as a short pulse (> 10 ms). It is then stored internally. The
memory can be reset only by applying the "Shutdown" command.
− All "Fast stop" commands are ANDed by the SIMOREG converter, i.e. all commands must be set to "No fast
stop" before the function can be deactivated.
− When n < n
(P370, P371) is reached for the first time, an internal interlock is activated which prevents the
min
drive from attempting to brake again if the motor is turned by external forces. The n < n
signal then disappears again.

Switch-on / shutdown (ON / OFF) terminal 37 - control word 1, bit 0

The "Switch-on / shutdown" (ON / OFF) function is controlled via the "Switch-on command of ON /
OFF1" (= ANDing between signal from terminal 37 and binector selected in parameter P654, level- or
edge-triggered, see below) and bit 0 of connector selected as the control word in P648.
The following operating modes are possible:
P648 = 9:
P648 ≠ 9:
P445 = 0:

The control bits in control word 1 are input bit-serially. "ON / OFF" is controlled via the
"Switch-on command of ON / OFF1".
The connector selected in P648 is used as control word 1. Bit 0 of the control word is
ANDed with the "Switch-on command of ON / OFF1" to produce the "ON / OFF"
command (ON only if both signals are log. "1").
The "Switch-on command of ON / OFF1" is generated as an AND operation between the
signal from terminal 37 and the binector selected in P654 (level-triggered, 0 = shutdown,
1 = switch-on).
