Energy-Saving Operation

Automatic Motor Power Supply Frequency and Supply Pressure Setting (with ECU2 and Windows software)
Automatically operates the system in energy-saving mode when the testing machine is in standby mode or depending on the test load status.
Note: Set manually via the Servo Controller 4830 if Windows software is not available.
Maximum 50 % savings EHF Series Electric Hydraulic Dynamic and Fatigue Testing System

Operation Example

Motor power supply frequency Supply pressure
During standby 35Hz 7-9MPa
Just before testing Automatically settings according to test conditions
During testing Periodically checks the displacement amplitude or test force to automatically set appropriate rpm or supply pressure.
Note: If the function to automatically set the motor power supply frequency and supply pressure is used, the test conditions cannot be changed during testing.
