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. UL approved as an
oveload protector for motors. See Section 12.6, on page 31.
 Electronic Inrush Current Limit (EICL™): Eliminates harmful inrush AC line
current during startup.
 Short Circuit: Prevents drive failure if a short circuit occurs at the motor (phase-to-
phase).
 Regeneration: Eliminates nuisance 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.
3.4 SELECTABLE
JUMPERS
 J1 (50/60 Hz): Used to set the drive for 60 Hz motors (factory setting) or 50 Hz
motors. See Section 7.2.1, on pages 19 and 20.
 J2 (X1/X2): Used to set the drive output for twice the motor rated speed (120 Hz
(factory setting) or 100 Hz). See Section 7.2.2, on pages 20 and 21.
 J3 (115V): The drive is factory set for 230 Volt AC Line input (J3 not installed). For
115 Volt AC Line input, install Jumper J1 (supplied). See Section 7.1, on page 19.
 CON1 (A/M): Used to set the drive for Automatic or Manual Start Mode. See
Section 7.3, on pages 21 and 22.
 CON2 (Forward/Reverse): Used to set the drive for forward or reverse speed
operation. See Section 7.4, on page 22. Also used to install the supplied
Forward-Stop-Reverse Switch. See Section 6, on page 18.
3.5 ADJUSTABLE
TRIMPOTS
 Minimum Speed (MIN): Sets the minimum speed of the motor. See Section 12.1,
on page 29.
 Maximum Speed (MAX): Sets the maximum speed of the motor. See Section 12.2,
on page 29.
 Acceleration (ACC): Sets the amount of time for the motor to accelerate from zero
speed to full speed. See Section 12.3, on page 29.
 Deceleration (DEC): Sets the amount of time for the motor to decelerate from full
speed to zero speed. See Section 12.4, on page 30.
 Slip Compensation (COMP): Used to fine tune the drive for improved load
regulation when required by the application. See Section 12.5, on page 30.
 Current Limit (CL): Sets the current limit (overload) which limits the maximum
current (torque) to the motor. See Section 12.6, on page 31.
