is a 4kW (5 HP) variable speed drive (VFD) from the Easy Altivar 610 series, specifically designed for controlling three-phase asynchronous motors in industrial applications like fans, pumps, and conveyors.
Key Specifications
Power Rating: 4 kW (5 HP) for normal duty; 3 kW (3 HP) for heavy duty.
Supply Voltage: 380V to 460V AC, three-phase.
Output Frequency: 0.1 to 500 Hz.
Overload Capacity: Up to 120% for slight overloads (normal duty) and up to 150% for significant overloads (heavy duty) for 60 seconds.
Protection Rating: IP20.
Communication: Integrated Modbus serial protocol via an RJ45 port; supports optional cards for Profibus DP V1 and I/O extension.
Dimensions & Weight: 145mm (W) x 297mm (H) x 203mm (D); weighs approximately 4.0 kg
serves as a motor speed controller that optimizes energy use and protects industrial machinery. It features 7 pre-programmed function blocks designed to handle approximately 90% of pump and fan applications out of the box.
Core Control Functions
Speed Regulation: Provides precise control of three-phase asynchronous motors across a frequency range of 0.1 to 500 Hz.
Motor Profiles: Supports multiple control modes, including Standard Variable Torque (ideal for fans/pumps), Constant Torque, and an Optimized Torque Mode for energy efficiency.
Macro Configurations: Includes pre-set software "Macros" like [Start/Stop], [PID controller], [Preset speed], and Multi-pump control for quick setup without complex manual programming.
Ramp Control: Features adjustable acceleration and deceleration ramps (Linear, S, or U curves) from 0.01 to 9000 seconds to prevent mechanical stress during starts and stops.
Built-in Protection & Diagnostics
The drive includes an intelligent system that monitors real-time health to prevent downtime:
Thermal Protection: Built-in monitoring for both the motor and the drive itself to prevent overheating.
Electrical Safeguards: Protects against overvoltage, undervoltage, line supply phase loss, and short-circuits between output phases and earth.
Operational Safety: Includes specialized checks for Motor Phase Break, overspeed detection, and control circuit breaks.
Automation Integration
I/O Connectivity: Equipped with 6 discrete inputs (2 of which can act as pulse inputs), 3 analogue inputs, and 2 analogue outputs for interfacing with sensors and PLCs.
Relay Outputs: Features 3 configurable relays (R1 for fault signaling, R2 and R3 for sequence logic).
Communications: Uses Modbus serial as standard (RJ45 port) and can be expanded with optional cards for Profibus DP V1 or additional I/O.
