Table of Contents

INPUT VOLTAGE SELECTION SWITCH - Switch selectable between 115 VAC and 230 VAC input.

MIN SPEED - (Minimum speed) Allows adjustment of the motor speed when the speedpot is set at minimum. This permits the user

to eliminate the "Deadband" on the main speed control, permitting zero calibration. Clockwise rotation of the "MIN" trimpot

increases output VDC.

ACCEL - (Acceleration) Allows adjustment of the motor acceleration from a minimum of 0.3 seconds to a maximum of 12 seconds.

The -15A option extends the maximum acceleration time to 30 seconds.

DECEL - (Deceleration) Allows adjustment of the motor deceleration from a minimum of 0.6 seconds to a maximum of 12 seconds.

The -15A option extends the maximum deceleration time to 30 seconds.

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 "DEADBAND" of the speedpot, providing full speed at maximum rotation. Rotation of the "MAX" trimpot

in the clockwise direction increases maximum output VDC.

I.R. COMP - (Speed Regulation) Allows adjustment of the circuitry that

controls the speed regulation of the motor. This feature controls

armature speed by changing the armature voltage to compensate

for increased or decreased motor loading. Clockwise rotation of the

"I.R. COMP" trimpot will increase gain compensation.

CUR. LIM. - (Current Limit) Provides protection from excessive arm-

ature current by limiting the maximum armature current the control

can provide. This enables adjustment of the maximum torque the

motor can deliver. Set Current Limit (CUR. LIM.) at 125% of the rated

motor current. Clockwise rotation of the "CUR. LIM." trimpot increas-

es the torque (current) the control will provide.

TACH INPUT SELECTION - Factory set at 3V per 1000 RPM, jumper

selectable (JU3) to 7V per 1000 RPM. Refer to "Tach Feedback"

section in "Control Modifications" for more information.

TERMINAL STRIP P1 - Barrier type terminal strip provides for connec-

tion of AC lines, motor leads, motor field (if necessary), and earth

ground.

TERMINAL STRIP P2 - Barrier type terminal strip provides for connec-

tion of speed potentiometer and any accessories and/or jumper

wires which control the drive.

RELAY - (Power Interrupt Relay's) Available only on the "RC" and the

"RE" versions, the relay's permits the switching of AC power with a

low current signal. For the "RE" version, the relay's will not allow start

up after power failure without manually restarting.
