CEM-MS-A
Description:
This closed loop position module provides synchronized motion. It may be applied in pairs, each
module driving a hydraulic cylinder for a “Master-Master” system of synchronized motion. This
pair of cylinders can quickly and accurately move hydraulic cylinder loads in unison. Or, it may
be applied in a “Master-Slave” mode, where up to three “Slave” axis will closely follow the
“Master” axis.
Position and velocity commands are from analog sources. Cylinder feedback is from an analog
source.
Stroke dependent deceleration is used to provide quick and repeatable positioning. Internal ramp
and velocity adjustments allow for easy system tuning.
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.
Output is an analog voltage, 0 to +/- 10v, suitable for directly driving a proportional directional
valve with on board electronics.
This module is easily adapted to a variety of system requirements. All variables are user adjusted
with easy to use 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.
