Product Description:
The SC752B-001-01 servo drive is produced by Pacific Scientific as a member of the SC750 Servo Drives series. It accepts three-phase 230 VAC input and delivers controlled output to permanent-magnet motors used in pick-and-place units, indexing tables, and other positioning axes. By converting motion commands into precise current waveforms, the drive helps industrial controllers maintain commanded velocity and position during repetitive duty cycles. This operating style supports axes that must start, stop, and reverse direction without large tracking errors.
During continuous operation on a 230 VAC supply, the unit can furnish 1.1 kW of output power to the connected motor, and it supports momentary overloads up to 2.2 kW during rapid acceleration. A peak phase current of 7.5 A is available, allowing the servo to overcome static friction or short bursts of increased load. Positional fidelity is held to ±4 arcmin, so commanded shaft angles stay within a narrow error band. Rotor position feedback is provided by a resolver, giving the control loop angle data when power is restored. This feedback method is well suited to industrial motion systems because it remains effective in electrically noisy environments. To protect the DC bus, the internal absorption network can dissipate 20 J of returned energy when the axis decelerates or is back-driven.
For sustained braking, the shunt regulator diverts heat through a resistor rated at 20 W, while short events up to 3 kW are handled without exceeding thermal limits. Non-volatile memory retains stored application data for at least 10 years, so long shutdown periods do not require periodic reloading. The enclosure weighs 5.9 kg, which suits panel mounting and adds stability within a control cabinet. The retained data supports equipment that may remain idle between production runs. The cabinet-mounted form also fits installations where several motion components are arranged in a limited footprint.
