Servo Yaskawa Sigma II

Servo Yaskawa Sigma II Amplifier is the ultimate servo solution for your automation needs. A single platform covers 30 watts to 55 kW and input voltages of 110, 230 and 480 VAC. The Sigma II amplifier can be set to torque, speed, or position control. A single-axis controller and a variety of network interface modules can be attached to the amplifier for the utmost flexibility. The Sigma II amplifier utilizes serial encoder technology to automatically recognize Sigma II rotary and linear servomotors. Advanced algorithms provide high performance tuning and suppression of machine resonance. A built-in keypad and serial port allow easy set-up and monitoring of the servo system. SigmaWin and SigmaWin Plus software can be used to capture torque, speed, and command references and SigmaWin Plus Professional can perform FFT and machine simulations.

Model Number Designation for SGDH Sigma II

Specifications for SGDH Sigma II

1 The power voltage must not exceed 230V +10% (253V). If it is likely that it will exceed this limit, use a step-down transformer. For types SGDH-08AE-S and SGDH-15AE-S, voltage is 200 to 230V + 10% -5%.

2 Use the servo amplifier within the ambient temperature range. When enclosed, the temperatures inside the cabinet must not exceed the specified range.

3 Speed regulation is defined as follows:

Speed Regulation = (no-load motor speed - full load motor speed) / rated motor speed x 100%
4 Forward is clockwise viewed from the non-load side of the servomotor, (counterclockwise viewed from the load and shaft end).

5 The built-in open collector power supply is not electrically isolated from the control circuit in the servo amplifier.
