Achieves optimum control of minor feedback control type KSP valves by detecting the spool position with a differential transformer. The constant current characteristics suppress the power supply voltage fluctuation, and the output current fluctuation due to temperature rise of the solenoid, to almost zero.
Achieves optimum control of minor feedback control type SEM valves by detecting the spool position with a differential transformer. The constant current characteristics suppress the power supply voltage fluctuation, and the output current fluctuation due to temperature rise of the solenoid, to almost zero.
02, 03 Size Controllers that perform shockless reverse acceleration / deceleration control of hydraulic cylinders using direct solenoid proportional switching valves. Suitable for machines that perform repeated reversal operations such as grinding machines.
Enables shockless speed reversal with heavy loads. The constant current characteristics suppress the power supply voltage fluctuation, and the output current fluctuation due to temperature rise of the solenoid, to almost zero.
Combining this controller with a driver for solenoid operated proportional valves enables setting of multi-step command input voltages. 6-step output voltage levels and the response time to reach these voltage levels can be set.
Used for 04, 06 size electromagnetic pilot type proportional directional flow control valve and applied to general industrial machinery except vehicles and ships.
