TABLE 3 - PROTECTION FEATURES
Feature Description
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
internal 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.
Prevents failure of power devices caused
by voltage spikes in the AC line.
Microcontroller Feature
Self monitoring and auto-reboot.
* UL approved as an overload protector for motors.
