Variable Speed Drive 5.5KVA

Quick Overview

Variable Speed Drive acts as a shock absorber of high induction current start loads. The VSD works by providing a constant torque load for hard starting air compressors, HVAC units and for variable torque loads for pumps and fans, lathes, mills, hydraulic lifts and hoists and conveyors.

Detailed Description:

Variable Speed Drives (VSD) are also known as Variable Frequency Drives (VFD).
They are a pure sine wave action providing the ability to control motor speeds.
By reducing the high impact shock loads you will reduce energy.


Symbol: Function Description
R.S.T: Input terminal of AC line power. (220V/240V AC class for single input and single phase output.
U.V.W: Output terminal of the inverter
P+.PR: Connector for braking resistor.
E: Ground terminal: the third method of grounding for 220V/240V.


Frequency Control Range: 0.1~2500.0Hz
Accuracy: Digital: 0.1%(-10~40℃); Analog: 0.1% (25±10℃)
Setting Resolution: Digital: 0.1Hz; Analog: 1‰ of max. Operating frequency
Output Resolution: 0.1Hz
Operator Setting Method: Press directly ←∧∨ to set.
Analog Setting Method: External Voltage 0-5V,0-10V,4-20mA,0-20mA.
Other Functions: Frequency lower limit, starting frequency, stopping frequency and three skip frequencies 
General Ramp Control: Selectable 4-speed steps ramp-up and -downtime (0.1-6500s).
Torque Control: Torque increase settable by max. 10.0%. The starting torque can reach 150% at 1.0Hz.
Multi-Inputs: 6 multi-function input terminals for 8–speed steps control, program operation, switching of 4-speed Ramp, UP/DOWN function, counter, external emergency stop and other functions.
Multi-Outputs:5 multi-output for displaying of running, zero speed, counter, external abnormity, program operation and other information and warnings.
Other Functions: Auto Voltage Regulation(AVR), Decelerating Stop or Coasting Stop, DC Braking, Auto Reset and Restart, Frequency Track, PLC Program Control, Traverse Control, Drawing Control, Auto Energy Saving, Carrier Adjustable (Up to 20KHz), etc.

Protection Functions
Overload Protection: Electronic relay protection motor drive.Drive(for constant torque150%/1 min. for the kinds of fan 120%/1min.)
Fuse Protection: Fuses provide open circuit overload protection.
Over-voltage 220V/240V class:DC Voltage >400V.
Under-voltage:220V class:DC Voltage <200V.
Restart After Instant Stop: Restart with Frequency Track after Instant Stop
Stall Protection: Stall protection in ramp operation
Output Short Circuit: Electrical circuit protection
Other Functions: Fin and heat sink over-heat protection, restriction of reverse running, direct start after power on, fault reset, parameter lock PID, one-drive-more, etc.
