• Electronic Inrush Current Limit (EICL™) – Eliminates harmful inrush AC line current
during startup. Models KBVF-21D, 22D contain ICL in lieu of EICL™.
• Short Circuit – Prevents drive failure if a short circuit occurs at the motor (phase-to-phase).
• Motor Filter – Reduces harmful voltage spikes to the motor.*
• Regeneration – Eliminates nuisance tripping due to bus overvoltage caused by rapid decel-
eration 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.
*Only Models KBVF-21D, 22D, 13, 23, 23D, 14, 24, 24D, 26D Contain Motor Filter.
3.4 Trimpot Adjustments
• Minimum Speed (MIN) – Sets the minimum speed of the motor. See Section. 13.1, on page 39.
• Maximum Speed (MAX) – Sets the maximum speed of the motor. See Section. 13.2, on page 39.
• Acceleration (ACC) – Sets the amount of time for the motor to accelerate from zero speed
to full speed. See Section 13.3, on page 39.
• Deceleration (DEC/B) – Sets the amount of time for the motor to decelerate from full speed
to zero speed. See Section 13.4, on page 39.
• Slip Compensation (COMP) – Maintains set motor speed under varying loads. See Section
13.5, on page 40.
• Boost (DEC/B) – In 50 Hz mode, the trimpot automatically becomes Adjustable Boost,
which can be used to set the Volts/Hz Curve for 50 Hz motors to obtain maximum perform-
ance. In 50 Hz Mode, the deceleration time is automatically set to the same as the accelera-
tion time. See Section 13.6, on page 41.
