A VFD slowly begins from zero speed and gradually work up to higher speeds. It offers precise, energy-efficient control of force and torque. When using a VFD, less current and power are required to start an AC motor. Thus, the problem of voltage sag and the damage it can inflict on expensive machinery and electronics is eliminated. This gives the AC motor longer service life through smoother startup process hence more savings on maintenance costs.
Precise electrical control:
- Speed levels are delivered as-needed avoiding slow operations that would otherwise use too much energy with fixed speed drives.
- The VFD can be programmed to restrict torque, keep the motor from surpassing a set torque threshold thereby holding back excess power that a fixed-speed controller would end up using wastefully.
It can implement power-on motor short-circuit detection, input/output phase loss protection, over current protection, over voltage protection, under voltage protection, overheating protection and overload protection.
Our VFDs also support Modbus Communication Protocol with local or remote parameter control
Why use a VFD?
Interlligent motor control
Reduction of peak current
Match the speed of the drive to exactly what your process requires
Lower noise levels from equipment
Reduce mechanical stresses on equipment to extend their lifetime, especially on startup with ramp up starts, instead of slam in starts.
For the vector control of three-phase AC asynchronous motors and three-phase AC permanent magnet
synchronous motors, as well as separation control.
SVC torque control is also supported - and better low speed stability and better low frequency load capacity.
Up to 4 x motor parameters can be set, and four motor switchings can be controlled
AIAO accuracy range is whithin 20mv.
