Description

Easy-to-use interface with integrated powerelectronics (H-bridge).
The actuator is speed controlled by means of a
PWM or 4-20 mA signal.
Proportional provides a wide range of possibilities
for customisation.

Note: Do not change the power supplypolarity on the Brown and Blue wires!
Power supply GND (-) is electricallyconnected to the housing
If the temperature drops below 0 °C, allcurrent limits will automatically increase to:
20 A for 12 V
15 A for 24 V

It is recommendable to have the actuator
activate its limit switches on a regular basis
to ensure more precise positioning

Signal GND:

For correct wiring of power GND andSignal GND4•

Current cut-offs should not be used as stop function! This might damage the actuator.
Current cut-offs should only be used in emergencies!

•Current cut-off limits are not proportional with the load curves of the actuator.
This means that the current cut-offs cannot be used as load indicator.

•There are tolerances on the spindle, nut, gear wheels etc. and these tolerances will havean influence on the current consumption for the specific actuator.
