1 Overview of the 5630 Stepper
Motor Drive
In this Chapter This Chapter introduces the 5630 Stepping Motor Drive.
Topics covered are:
•5630 definition
•Other system components
•How to use this manual
•Warranty
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.
Rev E 5630 Installation and Hardware Reference Manual 1 - 1
Features
(cont’d) Short circuit protection circuitry - latches the drive off and
lights the POWER FAULT LED if a short circuit occurs on
the motor outputs.
Optical isolation circuitry - isolates the user signals from the
drive power circuits for the step, direction, enable, and reset
command lines.
User
adjustments Mid-range instability control - eliminates loss of torque and
possible motor stalling conditions when operating at
mid-range speeds. This instability is a phenomenon of the
electronic, magnetic, and mechanical characteristics of a
stepping motor system. The enabled function damps
mid-range oscillations by advancing or delaying the switching
of the output transistors relative to the incoming pulse train.
Step size - sets the amount of shaft rotation per step. The
five settings range from full step to fractions of a full step
(microsteps). The microstep settings range from 1/2 to 1/125
for up to 25,000 steps/revolution with a standard 1.8ostepper
motor.
Idle current reduction (ICR) - reduces motor winding current
by 50% during motor dwell periods. ICR begins one second
after the last input step pulse occurs.
Current setting - sets the current supplied to the motor. The
available RMS current settings are 5, 6, 7.5, and 8 amps.

1.2 Other System Components
Overview The other components that, along with the drive, comprise a
complete motor control system are:
•Indexer or step source
•Motor
Pacific Scientific supplies a complete range of these
components for your needs. Selection and installation
guidelines for these components are described in Chapter 2,
Installing the 5630 Stepper Motor Drive.
System diagram The following diagram shows an installation of the drive in a
typical system. Your installation may vary from this
configuration.

2 Installing the 5630 Stepper
Motor Drive
In this Chapter This Chapter explains how to install the 5630 Stepper Motor
Drive. Topics covered are:
•Unpacking and inspecting the 5630
•Selecting other system components
•5630 safety
•Mounting the 5630 in your installation
•Connecting input/output cabling
•Selecting switch functions
2.1 Unpacking and Inspecting the 5630
Unpacking
procedure 1. Remove the 5630 from the shipping carton. Make sure all
packing materials are removed from the unit.
2. Check the items against the packing list. A label located
on the side of the unit identifies the unit by model
number, serial number, and date code.
Inspection
procedure Inspect the unit for any physical damage that may have been
sustained during shipment.
If you find damage, either concealed or obvious, contact your
buyer to make a claim with the shipper. Do this as soon as
possible after receipt of the unit.
Storing the unit Store the 5630 in a clean, dry place. The storage temperature
must be between -25 degrees C and 85 degrees C. To prevent
damage during storage, store the unit in the original shipping
carton after completing the inspection for damage.
