17429X.00 Drives
Leeson’s 17429X.00 Series drives are four-quadrant regenerative PWM drives for low voltage applications.
These open chassis drives come with the following features:
PULSE WIDTH MODULATION
•
Lower form factor than SCR drives (1.01 versus 1.37) throughout the motor speed range.
Motor runs quieter, with greater efciency and less maintenance.
FOUR QUADRANT REGENERATIVE OPERATION
•
See the Regenerative Drives section.
REGENERATIVE BRAKING
•
No contactors required. No electromechanical components to overheat or wear out.
ENABLE / BRAKE / DIRECTION TERMINALS
•
Choose a function by simply opening or closing a dry contact or through an open collector
transistor.
STATUS LEDs
•
Power and Fault LEDs provide a visual status of the drive.
OVER TEMPERATURE PROTECTION
•
Drive will fold the output power back to prevent from overheating. Drive will fault if it still
remains too hot.
MICROPROCESSOR BASED
•
Allows for factory programming of 17429X.00 drives for custom drives designed for OEMs.

MOTOR
TORQUE
NOTE: ARROWS IN SAME DIRECTION = MOTOR ACTION
ARROWS IN OPPOSITE DIRECTION = REGENERATIVE ACTION
MOTOR
ROTATION
Most non-regenerative variable-speed DC drives control current ow to a motor in one direction. The
direction of current ow is the same direction as the motor rotation. Non-regenerative drives operate
in Quadrant 1, and also in Quadrant 3 if the drive is reversible (See Figure 1).
Motors must stop before reversing direction. Unless dynamic braking is used, non-regenerative drives
cannot decelerate a load faster than coasting to a lower speed.
Regenerative drives operate in two additional quadrants: Quadrant 2 and Quadrant 4. In these
quadrants, motor torque is in the opposite direction of motor rotation. This allows regenerative drives
to reverse a motor without contactors or switches, to control an overhauling load, and to decelerate a
load faster than it would take to coast to a lower speed.

Installation
Mounting
WARNING
m
Do not install, rewire, or remove this control with input power applied. Doing so may
cause damage or serious injury. Make sure you have read and understood the
Safety Warnings section before attempting installation.
•
Drive components are sensitive to electrostatic elds. Avoid contact with the circuit board directly.
Hold drive by the chassis only.
•
Protect the drive from dirt, moisture, and accidental contact.
•
Provide sufcient room for access to the terminal block and calibration trimpots.
•
Mount the drive away from other heat sources. Operate the drive within the specied ambient operat-
ing temperature range.
•
Keep 2” of clearance on each side of the drive and 4” of clearance above and below the drive.
•
Prevent loose connections by avoiding excessive vibration of the drive.
•
Mount drive with its heat sink in a vertical plane. Four 0.19 in. (5 mm) wide slots in the chassis ac-
cept #8 pan head screws. If heat sink is mounted horizontally then derate the drive as specied in
Specications section.

Shielding guidelines
WARNING
m
Under no circumstances should power and logic leads be bundled together. Induced voltage
can cause unpredictable behavior in any electronic device, including motor controls.
As a general rule, Leeson recommends shielding of all conductors.
If it is not practical to shield power conductors, Leeson recommends shielding all logic-level leads. If
shielding of logic level leads is not practical, the user should twist all logic leads with themselves to
minimize induced noise.
It may be necessary to earth ground the shield at the drive end. If noise is generated by a device on
the drive, ground the shield at the end away from the drive. Do not ground both ends of the shield.
If the drive continues to pick up noise after grounding the shield then mount the drive in a less noisy
environment.
Logic wires from other input devices, such as motion controllers and PLL velocity controllers, must be
separated from power lines in the same manner as the logic I/O on this drive.

WARNING
m
Be sure that the potentiometer tabs do not make contact with the potentiometer enclosure.
Mount the speed adjust potentiometer through a 0.38 in. (10 mm) hole with the hardware provided
(see Figure 4). Install the circular insulating disk between the panel and the 10K ohm speed adjust
potentiometer.
Twist the speed adjust potentiometer wire to avoid picking up unwanted electrical noise. If speed
adjust potentiometer wires are longer than 18 in. (457 mm), use shielded cable. Keep speed adjust
potentiometer wires separate from power leads (BAT +, BAT -, A1, A2).
