Features
- Sensorless Flux Vector Control: Flux Vector Compensation with Static Auto-Tune provides excellent speed regulation with high torque loads throughout the entire speed range. Auto energy saving at light loads. Smooth motor torque.
- Electronic Inrush Current Limit (EICL™) Protection: Eliminates harmful inrush AC line current during power up.
- Run/Fault Relay: Can be used to turn equipment on or off, to signal a warning if the drive is put into “Stop” mode, or to signal if a fault has occurred.
- Start/Stop Switch: Provides electronic “Start” and “Stop” functions.
- Ride-Through: Provides smooth recovery to the previous set speed during a momentary power loss.
- Holding Torque at Zero Speed: Resists motor shaft rotation when the drive is in “Stop” mode.
-
Regeneration Protection: Eliminates tripping due to high bus voltage caused by rapid deceleration of high
inertial loads. - Undervoltage and Overvoltage Protection: uts down the drive if the AC line input voltage goes above or below the operating range.
- Short Circuit Protection: Shuts down the drive if a short circuit occurs at the motor (phase-to-phase).

Drive Options
- On/Off AC Line Switch: Disconnects the AC line.
- Forward-Stop-Reverse Switch: Provides motor reversing and stop functions.
- Run-Stop-Jog Switch: Selects speed setting from either the Main Speed Potentiometer or the JOG Trimpot.
- Signal Isolator: Provides isolation between a non-isolated signal source and the drive.
- Auto/Manual Switch: When used with the Signal Isolator, it selects the remote process signal or the Main Speed Potentiometer.
- Class “A” (CE) RFI Filter: Installs inside the drive.
- Liquidtight Fittings: Provides a liquid-tight seal for wiring the drive. Kit includes necessary liquidtight fittings.
