HD660 series frequency converter

Features and advantages

High aesthetic appearance, compact structure, 185-280kW with book shaped design, space saving, easy to install
High performance current vector control technology, no need for sensors, high speed stability accuracy, and wide application range. Support permanent magnet synchronous motor control
Wide power range, can support 0.4~1000kW (consult separately for 315kW and above), wide speed regulation range, V/F control can reach up to 3200Hz
Independent cooling duct design, equipped with coated panels specifically designed for harsh environments as standard. The entire series comes standard with a cooling fan, and there is no need to reduce capacity within an ambient temperature of 50oC. It has high environmental adaptability

easy to operate

Up to 16 speed segments can be achieved through built-in PLC or control terminals
Within 37kW, all specifications are equipped with built-in braking units, and within 160kW, an optional built-in braking unit is available. Optional braking resistor to enable fast braking of loads with large moment of inertia
Complete frequency converter and motor protection functions
Cooling fans of 5.5 kW and above can be replaced with just a screwdriver, making them easy to maintain
All series are equipped with button type pull-out panel as standard, and knob type panel can be selected

Intelligent in functionality

Quick current limiting function to avoid frequent overcurrent faults in the frequency converter
Multiple functions including timed control, speed tracking restart, automatic voltage adjustment, sleep and wake-up control, swing frequency control, etc., suitable for various industries and applications
Built in PID for convenient implementation of process control closed-loop control system
The carrier frequency and cooling fan can be automatically adjusted and turned on according to temperature rise and load, reducing the temperature rise and noise of the frequency converter

Connected to Expansion
The built-in RS485 interface integrates the standard Modbus protocol, making it easy to communicate with other devices. Optional EtherCAT communication
During an instantaneous power outage, the frequency converter can still continue to operate for a short period of time
Specialized PC software can be used to backup and restore parameters, supporting factory pre made parameters to save debugging time
