Description of function of inputs and outputs

8. Description of function of inputs and outputs

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.

Input circuit enable:

– SOLL

11K

22K

10nF

+ SOLL

ENABLE

+5V

2K2

1nF

390

Ω
