CEM-BPS-B
Description:
This closed loop position module has been developed for controlling hydraulic synchronization
systems. The typical synchronization accuracy is about 0.1% to 1% of the sensor length
(depending on the hydraulic system). Proportional valve 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.
This module is designed for use within a flow divider circuit. A flow divider (valve or gear pump)
will synchronize the axis but with limited accuracy. A proportional valve working in parallel to the
flow divider is compensating the flow error in one or both cylinders. The flow rate of this valve
should be in twice range of the flow error of the flow divider. This kind of synchronization control
is extremely stable and simple to use.
With the
AUTO SETUP
input feature, the offset error between both sensors can be measured
and compensated automatically. For this setup, the cylinders must be driven at the top or bottom
end.
The internal profile generation is optimized for stroke-dependent deceleration 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 the high resolution of the analog signals ensures good positioning
behavior. A wide range of analog signals are accepted. User may select either voltage or current
input mode.
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.
