Designated use
The SEC-ST-48-6-P01, referred to here as the SEC-ST, Smart
Electromotor Controller Stepper motor, has been designed for
use in control cabinets for controlling stepper motors in
2-string technology.
TheSEC-STmustbeoperatedinasafeworkingenvironment.
An EMERGENCY STOP circuit must be installed for the sys-
tem.
Operate the SEC-ST only under the permitted ambient condi-
tions.
The SEC-ST may only be operated in a stationary industrial or
commercial system. The electromagnetic resistance to inter-
ference of the power electronics is not designed for operation
in mobile systems, in households or in firms which are con-
nected directly to the low voltage network.
Install the SEC-ST screened and earthed in a control cabinet.
Otherwise, the electromagnetic compatibility (EMC) of the
power electronics cannot be guaranteed.
The SEC-ST may only be used as follows:
– in accordance with designated use
– in its original state
– without any modifications by the user
– in faultless technical condition.
If additional commercially-available components such as sen-
sors and actuators are connected, the specifiedlimits for pres-
sures, temperatures, electrical data, torques, etc. must not
be exceeded.
Please observe the standards specified in the relevant
chapters and comply with technical regulations, as well as
with national and local regulations.

1.3 Controller part
1.3.1 Brief description
Communication with higher-order controllers, e.g. program-
mable logic controllers (PLC) takes place via inputs and out-
puts.
The inputs are completely electrically isolated from each
other. This inputs can be actuated with either 5 V or 24 V.
(See section 1.6 User interfaces)
By means of push buttons, an individual step or travel can be
carried out in both directions of rotation.
1.4 Final output stage
1.4.1 Brief description
The integrated final output stage can control up to 6 A string
current. The string current can be set with the dip switch.
(see 1.7.2).
1.4.2 Internal monitoring
The end stage possesses an excess temperature cut-out, as
well as monitoring in the event of short circuit of the motor
strings between each other or against GND. (edition see 1.6.
