Benefits
Saves Time
Easy to Install and Simple to Operate
Does not require commissioning
With CSP™ you are up and running in less than 10 minutes.
Motors Last Longer
Proprietary CL Software
Provides overload protection, prevents motor burnout
and eliminates nuisance tripping.
UL approved as electronic overload protector for motors.
™*
Energy Saving
Uses only the power the application requires
Replacing constant speed with variable speed will
significantly reduce energy costs.
Economical to Use
Eliminates secondary enclosure
No holes to drill, no switches to install.
No need to derate drive for high starting torque applications.
Combines Soft Start with Variable Speed
Adjustable Soft Start.
Customization for OEM’s
When an off the shelf drive does not meet your needs, we will work with you
to provide a custom drive solution, Ready to Use, “Out-of-the-Box.”
Customization includes: Pre-calibrating or programming of a stock control, adding a custom label or branding,
custom software, PLC functions or designing a new control.
GFCI software allows the equipment to operate with Ground Fault Circuit Interruption circuit breakers or outlets.
*CSP™ = Common Sense Programming. Parameters are organized into easy-to-understand intuitive groups.
**KB MK-24DF.

Additional Features
Sensorless Flux Vector Control
Flux Vector Compensation with Static Auto-Tune provides excellent speed regulation
with high torque loads throughout the entire speed range. Auto energy saving at light
loads. Smooth motor torque.
Electronic Inrush Current Limit (EICL™) Protection
Eliminates harmful inrush AC line current during power up.
Multi-Function Output Relay
Can be used to turn equipment on or off, to signal a warning if the drive is put into
“Stop” Mode, or to signal if a fault has occurred
.
Jog-Local/Remote
Set the drive to Jog Mode or changes between Local (Keypad) or Remote Operation.
On/Off AC Line Switch
Disconnects the AC Line.
Built-in Potentiometer
Quickest way to change motor speed.
Ride-Through
Provides smooth recovery to the previous set speed during a momentary power loss.
Holding Torque at Zero Speed
Resists motor shaft rotation when the drive is in “Stop” mode.
Regeneration Protection
Eliminates tripping due to high bus voltage caused by rapid deceleration of high
inertial loads.
Undervoltage and Overvoltage Protection
Shuts down the drive if the AC line input voltage goes above or below
the operating range.
Short Circuit Protection
Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).
Drive Options
IODA Input/Output Multi-Function Board
Adds up to 17 points of additional I /O.
On/Off AC Line Switch
Disconnects the AC line.
