Introduction; Control Features - DART Controls 130 CONTROL SERIES Manual De Instrucciones

·
The 130 series reversing speed control is designed to provide instant reversing, quick precise
stopping or rapid cycling for a wide range of DC motor applications. The 130 series controls
outperform other dynamic braking and reversing controls by utilizing Dart's unique zero speed detect
and solid state assisted dynamic braking circuits. These circuits eliminate the contact arcing and
failed braking problems associated with other reversing and dynamic braking controls. Dart's zero
speed detect circuit also eliminates the motor problems associated with plug reversing a motor by not
reapplying power to the motor until zero speed is obtained.
·
The 130 series controls are also designed so that upon a power loss condition to the control or an E-
stop condition, the control will drop into a dynamic brake condition to safely and quickly bring the
motor to a stop and remain there until power is reapplied and a run condition is recognized.
·
The 130 series variable speed control come in an extremely small package size and fits the industry
standard footprint for both vertical and horizantal mounting patterns.
·
The 130 series variable speed control is available in a range of 500mA through 10Adc output at
120Vac or 240Vac input. This represent a Horsepower range of 1/50 through 1 at 90Vdc out or 1/25
through 2 at 180Vdc out.
·
The control is designed for DC Permanent Magnet and Shunt Wound motors in the above
horsepower ranges.
·
Incoming AC voltage is converted to adjustable full wave rectified DC voltage to operate the DC
motor. Also, a full wave field voltage is provided for shunt wound motors.
·
The control incorporates transient voltage protection with adjustable current limit which fits into a
compact package. It also features adjustable IR compensation along with adjustable minimum and
maximum speeds settings.
·
Available softstart option. (Consult factory for your OEM specific needs)
·
Listed, file #E78180
·
MINIMUM SPEED - Allows adjustment of the motor speed when the speedpot is set at minimum
(CCW). This permits the user to eliminate "Deadband" on the main speed control, permitting zero
calibration. Clockwise rotation of "MIN" trimpot increases speed.
·
MAX SPEED (Maximum Speed) - Allows adjustment of the motor speed when the speedpot is set at
maximum (CW). This permits the user to eliminate the top end "Deadband", which will provide full speed
at maximum rotation. Rotation of the "MAX" trimpot in the clockwise direction increases the maximum
motor speed.
·
IR COMP (Speed Regulation) - This allows for adjustment of the circuitry that controls the speed
regulation of the motor. The circuitry controls armature speed by changing the armature voltage to
compensate for increased or decreased motor loading. Clockwise rotation of the "IR COMP" trimpot will
increase compensation.
