Manual

Motor Horsepower Selection Jumper Allows the drive to be used on a wide range of motor horse-
power (1/8, 1/4, 1/2, 3/4, 1 HP) without recalibration or programming.
Diagnostic LEDs PC board mounted LEDs for Power On (ON), Drive Status (ST), and Overload (OL).
Run/Fault Relay Output Contacts Can be used to turn on or off equipment or to signal a warning if
the drive is put into the Stop Mode or a fault has occurred.
Barrier Terminal Blocks – Facilitate wiring of AC line, motor, ground (earth) and Run/Fault Relay Output
Contacts.
On/Off AC Line Switch Panel mounted. Used to turn the power on or off to the drive.
Pilot Light Panel mounted. Indicates that power is applied to the drive and the On/Off AC Line Switch
is set to the “ON” position.
Main Speed Potentiometer – Panel mounted. Provides adjustment of motor speed.
Jumper Selection of Drive Output Frequency Increases the motor speed up to two times the rated
RPM.
Compatible with GFCIs (with optional software).
3.2 PERFORMANCE FEATURES
Power Start™ Provides more than 200% starting torque which ensures startup of high frictional loads.
Slip Compensation with Static Auto-Tune and Boost Provides excellent load regulation over a wide
speed range.
Speed Range 60:1
3.3 PROTECTION FEATURES
Motor Overload (I
2
t) with RMS Current Limit – Provides motor overload protection which prevents
motor burnout and eliminates nuisance trips.*
Electronic Inrush Current Limit (EICL™) Eliminates harmful inrush AC line current during startup.
Short Circuit Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).
Regeneration – Eliminates tripping due to bus overvoltage caused by rapid deceleration of high
inertial loads.
Undervoltage and Overvoltage – Shuts down the drive if the AC line input voltage goes above or below
the operating range.
MOV input transient suppression.
Microcontroller self monitoring and auto-reboot.
*UL approved as an overload protector for motors.
