SIMOREG DC Master Operating Instructions
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
min
(P370, P371) is reached for the first time, an internal interlock is activated which
prevents the drive from attempting to brake again if the motor is turned by external forces.
The n < n
min
signal then disappears again.
9.3.3 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: The control bits in control word 1 are input bit-serially. "ON / OFF" is controlled via the
"Switch-on command of ON / OFF1".
P648
≠
9: 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").
P445 = 0: 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).
