Servo controller module

This is a slave module for the servo controller (Simple
Adaptive Control) for hydraulic or pneumatic of IRD series.
High accuracy position or load control for hydraulic or
pneumatic cylinder can be built up easily.

[Functions and Features]
● The data is transferred to the industrial network through IRD master
 module. (CC-Link, EtherNet/IP, PROFIBUS)
● Adopting Simple Adaptive Control (SAC) theory among other
 modern control theories, achieved robust control compensating
 automatically parameter change and time-variant influence in the
● Servo calculation is 200μs with inside DSP and it is independent of
 cycle time of host system.
● Possible to connect GY sensor directly as position feedback and
 build up high performance position control system with 1μm
 resolution. And also possible to connect incremental pulse encoder
 and build up position control system with the encoder's resolution.
● IRDS-SV is equipped with 2 ports for analogue input and it is possible
 to apply to load control with one load cell or two pressure sensors.
● Automatic transfer function : it can acquire feedback signal of various
 sensor from other IRDS slave module directly. And synchronization
 servo control to other IRDS-SV module is possible.
● Having two axes inside, possible to switch position (GY sensor or
 incremental pulse) to pressure (load) (analogue) control in operation.
● IRDS-SV is equipped with motion program function.
● Alarm : upper and lower limit of sensor, alarm of servo deviation and
● Self diagnosis function : internal IC error, cable error, sensor data
● RoHS compliant
