Product introduction

RDI67 series relies on TI company's DSP dual-core professional control motor chip, which supplies the international leading vector control algorithm to realize the real high-precision flux vector torque control. It has built-in pg vector control (VC), pg - free vector control (SVC) and V/F control modes, which widely aplied to high speed control accuracy, rapid torque response and high performance at low frequency. The integration of torque control, speed control and position control can meet the high performance requirements of customer applications. And, RDI67 has the ability to exceed the anti-trip performance of similar products and adapt to severe power grid, ambient temperature, humidity and dust, greatly improving the reliability of products.


Technical characteristics

Drive motor type:Ac asynchronous motor, Ac permanent magnet synchronous motor
Four control modes:PG vector control(FVC), PG- free vector control(SVC), 
V / F control, Torque control
Speed control range:PG vector control(FVC)1:1000
PG- free vector control(SVC)1:200
V / F control 1:50
Speed control accuracy:PG vector control (FVC)±0.2%
                     PG- free vector control (SVC)±0.5%
Starting torque:PG vector control(FVC):180 % rated torque/0.01Hz
              PG- free vector control (SVC)150% rated torque/0.25Hz
Torque control accuracy:PG vector control (FVC)±5%
                     PG- free vector control (SVC)±8%
Multi - motor switching: Two groups of motor parameters can realize the switching control of the two motors.
Motor overheating protection:Optional IO expansion card, analog A / 3 can accept input from motor temperature sensor
Supports multiple encoders:Supports differential, open collector, uvw, rotary transformer, sine and cosine encoder
Torque limitation and control: the "excavator" feature, automatically limits the torque during operation to prevent frequent overcurrent trips. Closed loop mode can realize torque control.
