1.1 5630 Definition
The Pacific Scientific
®
5630 Stepper Motor Drive is an
electronics package that converts step and direction inputs to
motor winding currents to control a two-phase bipolar
stepping motor.
The output current of the 5630 is switch selectable from 5.0 to
8.0 amps/phase RMS (7.1 to 11.3 amps peak) with a 160-volt
nominal dc bus. The 5630 leaves the factory set at 5.0
amps/phase RMS.
Standard
features
Bipolar chopper drive -controls motor current at 20 kHz
chopper frequency.
Internal power supplies - operate from the 115-volt ac input.
The main motor supply consists of a full wave bridge rectifier
into a capacitive input filter with in-rush current limiting.
Shunt regulator circuitry -protects the drive by removing
energy from the supply if the dc bus voltage exceeds 200 volts.
This feature protects the circuitry from excessive voltage that
may be generated under certain motor deceleration
conditions.
