SED2 Operation & Maintenance Manual
46 Siemens Building Technologies, Inc.
Start Motor
Default setting: Terminal 5 (DIN 1, high).
Additional settings: See Selection of Command Source parameter P0700 and Function of
Digital Inputs 1 to 8 parameters P0701 through P0708.
NOTE: The ramp-up and ramp-down smoothing times influence the motor’s start and stop
behavior. For more information, see Ramp-Up Time parameter P1120 and Ramp-
Down Time parameter P1121 in the Appendix A: Parameter Reference List section of
this document.
Stop Motor
There are several ways to stop the motor:
Default setting:
OFF1 Terminal 5 (DIN 1, low).
OFF2 OFF button on BOP/AOP; sustained pressing of the OFF button (two seconds) or
repeated pressing of the button (in case of default settings not possible without
BOP/AOP).
Additional settings: See Selection of Command Source parameter P0700 and Function of
Digital Inputs 1 to 8 parameters P0701 through P0708.
Reversal of the Motor’s Direction of Rotation
Default setting: Terminal 6 (DIN 2, high).
Additional settings: See Selection of Command Source parameter P0700 and Function of
Digital Inputs 1 to 8 parameters P0701 through P0708.
OFF Functions
OFF1
This command (by eliminating the ON command) stops the SED2 within the selected ramp-down
time.
See Ramp-Down Time parameter P1121 to change the ramp-down time.
NOTES:
1. The ON and the consecutive OFF1 command must have the same source.
2. If the ON/OFF1 command is set for more than one digital input, only the last set digital input
is valid; for example, DIN3 is enabled.
OFF2
This command causes a free coasting of the motor to standstill (impulses for the power section of
the SED2 are disabled).
NOTE: The OFF2 command may have one or several sources. By default, the OFF2
command source is set to BOP/AOP. This source remains even if other sources are
defined by Selection of Command Source parameter P0700 or Function of Digital
Inputs 1 to 8 parameters P0701 through P0708.
OFF3
An OFF3 command causes the motor to decelerate rapidly.
