2 enable inputs +24 V with STO function
(not EG type tested)
4 digital inputs +24 V/3.7 mA/5 ms
1 digital output +24 V/0.2 A/short-circuit protected
The S-DIAS motor output module SR 012 allows the connection of DC
brush motors with a phase current up to 5 A. The operating modes PWM
control, as well as current and speed regulation via IxR compensation are
supported.
With the two Enable inputs, the Safety function STO is implemented (not
EG type tested).
The module also has four digital inputs (+24 V/3.7 mA/5 ms) and a short-
circuit proof digital output (+24 V/0.2 A). The +24 V supply voltage for the
digital in- and outputs are monitored for under voltage.

The motor supply must be connected with an appropriate DC-link capaci-
tance (at least 2000 µF / 100 V).
Braking a DC motor
When braking a DC motor, a generative process can occur whereby the
kinetic energy of the motor is converted into electrical energy. The energy of
the motor is thereby fed back into the supply of the DC motor output stage;
this then increases the supply voltage. It should be noted that the feedback
voltage supply voltage of 65 V cannot be exceeded!
The external capacity of the motor supply is may be needed. If the capacitors
in the power supply are insufficient, a regen resistor, which converts the ex-
cess energy into heat must be connected to the DC motor output stage.
When selecting the power supply, it is important to ensure that it is appropri-
ately feedback-resistant up to the maximum feedback voltage.
Use only conductors that are rated for at least 75 °C!
There is no motor thermostat analysis in the motor output.
Incorrectly set parameter or incorrect wiring can lead to destruction of the
motor. It is important that the motor currents and the I2T settings (A-I2TT, A-
I2TERR), which can be defined via the LASAL Class2 Tool in the DIAS-Drive
Editor, must be taken into account.
