4.5. Commissioning
Select the required operating mode by setting the according jumpers on the left side of the unit. Refer
to the printing on the front plate.
Required selection of:
•
operating mode
•
output current range
•
Input for set value
Connect motor, control inputs e.g. set value, enable and if necessary an additional encoder or tacho
to the drive.
Connect power supply.
Enabling and adjustment referring to manual.
5. Description of inputs and outputs
pin number in ( )
5.1. Inputs
5.1.1. Set value (18,19)
The input for set value is internally connected to an differential amplifier.
Input range of set value: -10 V...+10 V
Input impedance: 20 kOhm
Definition of polarity: positive set value (+Set value) > (- Set value)
negative set value (+Set value) < (- Set value)
5.1.2. Enable (14)
High potential at the input enable will activate speed/torque control and voltage will be applied to the
motor winding. Leaving this input open or pulling it to GND-potential will result in disabling the unit
5.1.3. Disable Fwd (12)
5.1.4. Disable Rev (13)
these direction depending inputs have to be connected directly or via a NC to high potential. If not
connected or connected to GND the unit will be disabled at the corresponding set value.
