Specification：
This VFD can be used for constant torque loads ( such as hard starting: Air compressors, HVAC units) and variable torque loads (such as pumps, fans, etc). It can be used as a motor speed control and a phase converter. The input for this VFD is 1 phase . This item use Sine wave PWN(SPWM ) for the control system and performance excellently.
Connection way: Input : 220VAC(+/-5%) 1 or 3phase（for 1 -phase input, just connect the input wire to the R and S terminals） Output : 3phase 220v. Frequency :0-50hz/60hz. 0-400hz
Multiplex terminal: Unlike other inexpensive VFDS, this VFD has two sets of terminal functions,Rich of digital and analogy control terminals for versitile control,optional MODBUS (RS485) extension,diversified parameter setting
Safety performance: Take advantage of various protection ways such as Motor short-circuit detection at power-on, output phase loss protection, over-current protection, over-voltage protection, under-voltage protection, overheat protection, overload protection and etc.
Good Noise Control: The product has the advantages of low noise and low electromagnetic interference, which are achieved by the excellent PMW control technology and component compatibility design. There is enough space for cooling between each component, and the product casing is designed with multiple holes, the above features can make this VFD have a longer service life.
General Control: Ramp Control - Selectable 4-speed steps ramp-up and -down time (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 torque 150%/1 min. for the kinds of fan 120%/1min.）Fuse Protection:When the fuse breaks , the motor will stop. Over-voltage 220V 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 over-heat protection, restriction of reverse running, direct start after power on, fault reset, parameter lock PID, one-drive-more, etc.
