In ( ) the pin number
8.1. Inputs
8.1.1 Set value (17, 18)
the input for set value is internally connected to an differential amplifier.
input range of set value: -10 V...+10 V
input impedance:
20 k
Ω
definition of polarity:
positive set value (+Set value) > (- Set value)
negative set value(+Set value) < (- Set value)
Input circuit set value:
8.1.2 Enable (13)
high potential at the input enable will activate speed/torque control and voltage will be
applied to the motor winding. Leaving this input without connection or pulling it tho GND-
potential will result in disabling the unit.
