FREQUENCY INVERTER INTRODUCTION
(High Performance & Vector-Control AC Driver)
Quick response is available by using special DSP chip which is used to Control high speed motor The modular hardware design can make system work with high stable

Performance
Perfect shape design with fluent outline is popular with customers The fans of AC driver can be replaced easily by adopting independent wind Channel. The effect of heat dissipation is very good Users can choose the following four control method according to their Application needs: Vector Control without PG Card; Vector Control with PG Card; Torque Control; V/F Control There are two ways of analog signal output and one way of pulse signal Input. More powerful multi-functional spare terminals are available for choice The special function of auto-adaption can effectively solve the problem of Frequent trip-off caused by over current AVR function can make the AC driver don't stop when instant power-fail Occurs.

The functions like PID inside, *6 steps of speed control and simple PLC can Meet different application needs Users can choose PC or PLC to control the upper computer by RS**5 Communication interface with MODUS RTU ASCII protocol inside
