4 Functional Description
4.5 Motor with SCDC Speed Controller
4.5.1 Connection functions
The servomotor with integrated SC speed controller supports the following functions and/or operat-
ing modes:
„ Controlling the speed via the supply voltage.
„
Controlling the rotational direction via the polarity of the supply voltage.
„
Integrated motor current limiting.
„ Optionally, the SCDC Speed Controller SCDC can be supplied with a pre-programmed fixed speed
(on request).
The level of the supply voltage determines the motor speed.
The polarity of the supply voltage determines the motor's direction of rotation.
NOTE
The minimum supply voltage must be noted and observed. See Chapter 3.3.5 “Motor with SCDC
Speed Controller” .
Mot + (core 1)
Positive supply voltage connection.
Mot - (core 2)
Negative supply voltage connection.
4.5.2 Configuration
SCDC Speed Controllers are pre-configured in the factory.
On request, the following parameters can be changed, as for the SC Speed Controllers:
„ Current limiting values
„
Fixed speed value
„
Speed limiting
„ Controller parameters
It is not possible for customers to change these parameters.
4.5.3 Technical information
SCDC Speed Controllers, like the SC Speed Controllers, have integrated I²t current limiting and a
thermal cut-out.
