V/F Control VVVF AC Drive

V/F control VVVF drive is dedicated for the construction of the load characteristics and control requirements of the construction of specialized research and development of drive control. Integrated construction lifter electrical logic, frequency conversion control, brake power, overload protection function, increase the text display, automatic speech, floor call, flat layer, GPRS function. These can satisfy the energy saving, low speed and medium speed construction lifter in the high-end application requirements.
V/F control VVVF drive product features:
Wide range of application:
It is suitable for the V/F control of asynchronous motor and synchronous motor, effectively reduce the users inventory, and don’t need to consider the motor type of compatibility problem.

Excellent property:
Excellent control property: 1:100 ratio(SVC), 0.5Hz/150% of start torque, multiple brake torque model, which without braking resistor can achieve rapid flux braking mode.
Strong environment adaptability:
The product have compact structure design, independent air duct design, a variety of installation methods, sharply increase the power density, effectively reduce the user installation requirements, which are meet the demanding the user’s installation conditions. The full independent air duct design can effective improve the AC drive protection effective and adapt a variety of complex user install environment. Compatible floor installation and flange installation of two kinds of installation mode that adapt to different user needs.

Abundant function:
Two sets of motor parameters, V/F separation, virtual terminal function, speed tracking, relay output delay, etc.; Two sets of motor parameters can satisfy customer use different motor shared in a AC drive, and effectively reduce the customer equipment investment; V/F separation function meet all kinds of VVVF AC drive to achieve V/F curves flexible setting .
