User Guide

• 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.
3.4 Trimpot Adjustments
• Minimum Speed (MIN) –
Sets the minimum speed of the motor. See Sec. 13.1, on pg. 39.
• Maximum Speed (MAX) – Sets the maximum speed of the motor. See Sec. 13.2, on pg. 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 pages 39 and 40.
• Slip Compensation (COMP) – Maintains set motor speed under varying loads. See Section
13.5, on pages 40 and 41.
• 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 pages 41 and 42.
• Current Limit (CL) – Sets the current limit (overload) which limits the maximum current
(torque) to the motor. See Section 13.7, on pages 42 and 43.
