SIMOREG DC Master Operating Instructions
Sequence of operations for shutting down drive:
1. Enter the "Shutdown" command (e.g. via terminal "Switch-on / shutdown”)
2. Decelerate along ramp-function generator ramp
3. Wait until n < n
min
(P370, P371)
4. Output signal "Close holding or operating brake" (binector B0250 = 0)
5. Wait for brake closing time (P088) to run down
6. Input i
set
= 0
7. Ramp-function generator and n controller are disabled
8. The pulses are disabled when I = 0
9. The "Line contactor closed" relay drops out
10. The converter reaches operating state o7.0 or higher
11. Delay for field current reduction (P258) runs down
12. The field is reduced to a parameterizable value (P257)

−
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.
−
Changing the parameter setting between level and edge triggering affects the "Switch-on",
"Shutdown" and "Crawl" commands.
−
The "Switch-on" and "Crawl" commands are applied alternately when edge triggering is selected,
i.e. a "Switch-on" edge at terminal 37 cancels a "Crawl" function triggered beforehand, and a
"Crawl" edge at a binector selected in P440 cancels an active "Switch-on" edge.
−
The converter cannot be restarted automatically after a brief failure of the electronics power supply
when edge triggering is selected.
−
In order to ensure that "Shutdown" still works after "rewiring of parameters", if lower current or
torque limits are applied or when additional setpoints are injected, certain functions are
automatically deactivated when the "Shutdown" command is entered.
All torque limits are made inoperative while the drive brakes down to n < n
min
. Of all the current
limits, only the system current limit (P171 and P172), the speed-dependent current limit and the
limit derived from I
2
t monitoring of the power section remain operative.
