The 5630-026 is a stepper motor drive in the 5000 Series by Pacific Scientific. This unit, designed to be used with two-phase step motors, effectively converts direction and step input into motor winding currents that control the steps of motors. The output current can be conveniently controlled between 5 to 8 amps, with the factory default setting being 5 amps per phase RMS and a peak capability of 11.3 amps. The 5630-026 comes with a noteworthy mid-range instability control feature that minimizes torque loss and prevents motor stalling at mid-range operational speeds, ensuring efficient performance. This is achieved by monitoring and managing the mid-range oscillations of the stepping motor system which typically arise from the mechanical, magnetic, and electronic components of the system. This stepper motor drive also has a bipolar chopper drive, controlling the motor current up to 20 kHz, and internally features power supplies that operate from a 115-volt AC input. Inbuilt with a full-wave bridge rectifier in the main motor supply, it has inrush current limiting and shunt regulator circuitry that protect the drive by eliminating any excess energy exceeding 200 volts. The 5630-026 model includes short circuit protection that enhances its reliability by automatically shutting off when necessary, ensuring the continuous safe operation of your equipment.

5630-026 by Pacific Scientific is a Stepper Motor Drive that is ready to run intelligent motion systems to economical board level drivers. Featuring high performance magnetic and electronic innovations, this 5630-026 features a Functionality & Drive Configuration of Integral power supply and a Power Level of 11.3 A peak, 8 A rms, 160 Vdc with integral power supply.
