Optidrive E3 VFD Invertek – Compact General-Purpose Variable Frequency Drive
The Optidrive E3 VFD Invertek is a versatile, compact general-purpose variable frequency drive (VFD) manufactured by Invertek Drives. Designed to deliver energy-efficient speed and torque control for standard AC induction, Permanent Magnet (PM), Brushless DC (BLDC), and Synchronous Reluctance (SynRM) motors, the Optidrive E3 VFD Invertek combines high reliability with quick setup capabilities.
As shown in the product image, the drive features a distinctive lilac enclosure with an intuitive integrated 7-segment LED keypad interface. Built to simplify commissioning for OEM machinery, HVAC systems, and industrial plant automation, it requires just 14 basic parameters for standard motor startup. It is available in both IP20 panel-mount frames and IP66/NEMA 4X outdoor washdown-rated enclosures.
Key Features of the Optidrive E3 VFD Invertek
-
Rapid Commissioning (14 Basic Parameters): Features factory default settings suitable for most industrial motor applications, allowing immediate out-of-the-box operation.
-
Multi-Motor Compatibility: Directly controls 3-phase AC Induction Motors, Permanent Magnet AC Motors, BLDC Motors, and Synchronous Reluctance Motors.
-
Application Macro Modes: Includes pre-configured macros for Industrial, Pump, and Fan modes (including Fire Mode and internal PID control).
-
Sensorless Vector Control: Delivers precise speed control and high starting torque across low RPM operating ranges.
-
Built-In Industrial Communications: Equipped with standard Modbus RTU and CANopen fieldbus connectivity via RJ45 ports.
-
Integrated EMC Filter: Features an internal EMC filter to suppress radio-frequency interference and ensure compliance with European standards.
Common Applications and Industrial Usage
The flexible motor control modes and robust construction of the Optidrive E3 VFD Invertek make it a popular drive choice for diverse commercial and industrial tasks:
-
HVAC Air Handling & Ventilation Fans: Utilizes Fan Mode and Fire Mode to maintain building airflow and override safety trips during emergency ventilation events.
-
Pumping & Fluid Management Systems: Uses integrated PID feedback and Sleep/Standby functions to regulate water pressure and reduce pump wear.
-
Conveyors & Material Handling: Provides smooth acceleration/deceleration ramps (0.01 to 600 seconds) and high starting torque for loaded belt conveyors.
-
Industrial Processing Equipment: Controls mixers, centrifuges, and machine tools requiring compact physical footprints.

Installation Guidelines and Best Practices
Note: Ensure all incoming line power is isolated for at least 5 minutes before carrying out wiring or terminal connection work.
Use Shielded Motor Cables: Always connect screened/armored motor cables between the drive output terminals (U, V, W) and the motor, grounding the screen at both ends.
Verify Supply Rating: Check that the incoming line voltage matches the VFD nameplate (1-Phase vs. 3-Phase) prior to applying mains voltage.
Fast Parameter Transfer: Use an optional Optistick Smart accessory to transfer drive parameter sets wirelessly via Bluetooth or NFC using the OptiTools Mobile app.
