All entries in this manual refer to both the 230-TOH and the 430-
TOH modules, unless otherwise specified.
This manual is organized for the convenience of the operator.
Section 2, “Mounting and Pin Assignments,” provides diagrams and
reminders that are necessary, even for the experienced user and
installer.
Complete specifications (Section 3) will provide easily referenced
information concerning all aspects of installation, power and inter-
face requirements, as well as performance specifications.
The “Functional Description” (Section 4) provides operational in-
formation in narrative form. This presentation is useful in design,
diagnostic, and troubleshooting.
Section 5, “Pin Descriptions,” provides detailed information on
functions of the input connections in advance of using the equip-
ment.
Section 6, “Operating Instructions,” lists the procedures for using
a remote potentiometer, setting base speed and high speed and the
acceleration and deceleration potentiometers.
The following sections contain additional drawings and informa-
tion useful for setting up and operating the oscillator modules.
1.3.2 LOGIC and VOLTAGE CONVENTIONS
Throughout this manual, the following conventions are followed:
•
The designation “Vo” signifies the logic signal common terminal.
“Vom” signifies the motor supply voltage common terminal. Vom is
internally connected to the drive module’s aluminum case.
•
All logic functions are
low true logic
. A logic low or logic 0 will
activate a function and a logic high, or a logic 1 will deactivate a
function. Thus,
IN THIS MANUAL THE TERMS ACTIVE OR ACTIVATE WILL
IMPLY A LOGIC LOW CONDITION AND THE TERMS INACTIVE
OR DEACTIVATE WILL IMPLY A LOGIC HIGH CONDITION.
•
In cases where the function changes with a change in logic state,
WARNINGS
•
Voltage is present on unprotected pins when unit is opera-
tional.
•
No short circuit protection is provided in this unit.
LIMITS OF USE
•
Superior Electric disclaims any liability for operating this unit with-
out the correct filter capacitor.
•
Assure motor compatibility before using the unit.
•
Case temperature must be maintained between 0 and 75 degrees
C. (32 and 167 degrees F).
•
Reconfiguration of the circuit in any fashion not shown in this
manual will void the warranty.
SECTION 1: INTRODUCTION
1.1 FEATURES OVERVIEW
The 230-TOH and 430-TOH are differentiated as follows:
MOTOR CURRENT
VA
PER PHASE
PER PHASE
230-TOH
2 Amps peak
56 VA nominal
430-TOH
3.5 Amps peak
96 VA nominal
The 230-TOH and the 430-TOH are low-cost pulse generators that
are integrally packaged with a motor drive unit and a heat sink. These
translators are low to medium power, high efficiency units that can
control a wide range of Superior Electric SLO-SYN two-phase step-
ping motors with 4, 6 or 8 leads. These modules provide full-and
half-step operation.
The translator modules are designed as small, easily mounted
packages and allow for the external control of basic motor functions
as well as the manual adjustment of motor speed, acceleration and
deceleration.
1.2 INSPECTION PARTS LIST
The drive module, oscillator, and heat sink come fully assembled as
a single unit and are marked with the part number, either 230-TOH
or 430-TOH.
The terminal strip that is used to connect the motor leads to the
Oscillator/Driver unit is packaged separately, and is identified as
Superior Electric part # B215744-007.
1.3 USING THIS MANUAL
This manual is an installation and operating guide to the 230-TOH
and 430-TOH modules. All the information provided is necessary for
using these modules successfully.
We strongly recommend that this manual be read thoroughly
and completely before attempting to install and operate the
equipment.
1.3.1 Organization
•
All Windings Off should be used with caution, as all holding torque
is lost.
NOTES:
1. Clockwise and counterclockwise directions are properly ori-
ented when viewing the motor from the
lable end.
2. Motor connector, J4, consists of 7 pins arranged symetrically
around the center pin. If the connector is inadvertantly ro-
tated 180 degrees, motor direction (CW, CCW) will be reversed.
Motor direction can also be reversed by swaping the two motor
connections of the
same phase
(for example, by swapping
M1 and M3).
