Description:
This closed loop position module has been developed for controlling hydraulic positioning drives.
Proportional valves with integrated or external electronics can be controlled with the differential
output. Output is an analog signal of either voltage, 0 to +/- 10v or current 4-20mA, suitable for
directly driving a proportional directional valve with on board electronics.
The internal profile generation is optimized for stroke-dependent deceleration or the NC control
mode. The controller and the controller settings are factory preset to typical requirements and can
be optimized for the control behavior as required. The optimized control function offers a high
degree of precision together with high stability for hydraulic drives. The movement cycle is
controlled via the external position and speed inputs.
The high resolution of the analogue signals ensures good positioning behavior. A wide range of
analog signals are accepted. User may select either voltage or current input mode. These inputs
are easily scaled to match system requirements.
Forward and Reverse “jog” inputs allow for manual load control. A user definable window for “in
position” triggers an output for communication to the next machine function.
This module is easily adapted to a variety of system requirements. All variables are user adjusted
with easy to use
CHI-PC
software on your Microsoft Windows laptop. Control variables are
stored in non-volatile memory internal to the module. All variables can be read by the laptop, and
reproduced exactly on other modules.
