Product Description:
The SC723A-001-PM72032 Servo Controller is designed for reliable and economical motor control. It is suitable for both analog and digital configurations. The unit integrates power supply and shunt regulation for seamless operation with separate inputs for control logic and motor bus power.
This SC723A-001-PM72032 servo controller from Pacific Scientific supports an input voltage of 120 Vac (± 10 %, - 15 %) or 240 Vac (± 10 %, - 15 %) for bus power. The control logic accepts 90 to 264 Vac, 47 to 63 Hz, single phase supply. The bus voltage reaches 320 Vdc with 240 Vac input or 160 Vdc with 120 Vac input. It consumes 500 mA at 120 Vac or 250 mA at 240 Vac for logic power. The unit handles 4.5 Arms of RMS bus current and delivers a peak output current of 7.5 A at + 50 °C for 5 seconds with a continuous stall current of 3.8 A. The peak output power of the model at 240 Vac (3 phase) is 2.2 kW and 2.0 kW for 240 Vac (1 phase). The continuous power ratings are 1.1 kW for 3 phase and 0.8 kW for 1 phase at 240 Vac. The integrated shunt regulator supports peak absorption of up to 3 kW and 20 W continuous. It operates as a 4 quadrant controller and ensures safe motor control by maintaining encoder and fault information even when motor power is off.
This SC723A-001-PM72032 servo controller also supports quadrature encoder inputs or step and direction commands for indexing or electronic gearing applications. The device is engineered for both single axis and multi axis configurations and is adaptable to varied automation needs. The controller uses a removable personality module for quick setup and maintenance.
Frequently Asked Questions about SC723A-001-PM72032:
Q: How does the SC723A-001-PM72032 manage thermal stress during peak load operation?
A: The SC723A-001-PM72032 delivers a peak output current of 7.5 A at +50 °C for 5 seconds. This allows it to maintain motor performance under heavy demand while avoiding thermal overload.
Q: Can the SC723A-001-PM72032 controller operate reliably with both single and three-phase power input?
A: It supports 240 Vac input in both single and three-phase configurations, offering 2.0 kW and 2.2 kW peak output respectively. This makes it versatile for varied industrial power environments.
Q: What kind of signal control inputs can I integrate with the SC723A-001-PM72032 model?
A: The controller accepts quadrature encoder feedback or step and direction command signals. This flexibility supports precise indexing and electronic gearing applications.
Q: Does the SC723A-001-PM72032 handle logic and bus power differently during operation?
A: It uses separate inputs for control logic and motor bus power, enhancing electrical isolation. Logic accepts 90–264 Vac, while bus input handles either 120 or 240 Vac ranges.
Q: How does the SC723A-001-PM72032 servo controller maintain stability during regenerative load conditions?
A: It integrates a built-in shunt regulator that absorbs peak loads up to 3 kW and 20 W continuously. This prevents overvoltage conditions and maintains safe motor control in dynamic cycles.
