Product Description:
This SC104-001-T4 servo controller offered by Pacific Scientific has three external terminals to connect a shunt regulator resistor. The controller’s DC bus protected lines are fed to a diode input/SCR input bridge rectifier. This product’s phase currents are controlled using a pulse width modulation technique. The device’s velocity loop has one current mode input and two differential voltage mode inputs. This unit’s velocity feedback and commutation are achieved with a Tachsyn transducer. It has several protection and diagnostic circuits. The controller is protected against tachometer fault conditions by an internal circuit.
This product’s Bus Enable signal gets activated if no faults are present. The device’s fault latches are cleared by a PUR signal. This unit drives brushless servomotors equipped with permanent magnets. It doesn’t need a brushless tachometer for torque block operation. This controller’s voltage levels can exceed 400 VDC. The product’s PWM current control has a high frequency. This device is designed to offer trouble-free operation. The unit features an in-built dynamic braking capability. It delivers a peak current limit adjustment.
The controller operates with a 230 VAC +10%/-15% input voltage and a 47 Hz to 63 Hz input frequency. This product’s operating temperature shouldn’t be over 60 °C. The device features less than 1.01 form factor. This unit supports a peak output current for five seconds. Its surrounding air must be free of corrosive contaminants. The servo controller’s continuous power and current ratings are derated in a linear pattern to 70% at 60 °C. This product’s installation has to ensure sufficient flow of air in the cabinet. The device weighs close to 16 lbs. This unit’s front panel must be replaced after its setup. It delivers excellent performance.
