SDD860 Series High Performance Vector Control Drive
SDD860 AC Drive models.


When you need simplicity and intelligence in one self-contained solution, The SDD800 covers a wide range of options. Ideal for variable and constant torque applications from pumps and fans to conveyors and mixers as well as many other variable and constant torque applications. Enjoy plug and play convenience right from the start. No customizing or special product engineering required.
Excellent unique ventilation design with powerful big fans.

Features of products.
It has V/F, OLV( open loop vector control ), CLV ( close loop vector control), Compatible with variety of encoder such as collector, differential / rotary transformer .
1). Wide speed control range
a). Sensorless open loop vector (OLV) control: 0.5 to 400Hz ( 1:100/50Hz datum point )

b) . Sensor with PG card: 0.5 to 400Hz ( 1:100/50Hz datum point) Good current waveform

2). Response speed improving
Adopting high speed 32 bit DSP to get the high speed response of frequency inverter.
a.) The response 100rad/s, precision ĦÀ 0.5% in sensorless open loop vector control mode.
b.) The response 250rad/s, precision ĦÀ 0.01% in sensor close loop vector control mode.

3). High torque output under low speed to meet some big inertia load conditions
High torque under low speed achievement.
Adopting advanced current vector control technology and motor parameters detecting to make high torque under low speed is available.

4). Torque control in OLV and CLV

5). Powerful PID function
Possible to set PID1 and PID2 combination function, free switch between two PID parameters.
PID module can be used for external unit using with professional PID control.
Flexible PID control with sleep mode, configure waking up frequency, sleep frequency, that is very easy using for water supply.

6). Stall protection function
when over current, over voltage occurs, the output frequency will be reduce, and the output frequency /voltage under limit value, the output frequency will restore.
Appropriate acceleration and deceleration will be select according to the load control the motor stopping time even power loss instantaneous Stall protection illustrations configure.

7). Speed tracking restart function
Detect motor speed and rotation direction automatically, no any trip during start even in reverse running status.

8). S curve function
S curve can improving the impact during the start and stop processing, it is very useful in crane, elevator application

9). 16 segment speed circle running, easy to configure.

10). Advanced energy saving technology
SDD800 series inverter can detect the load status to control the output voltage and power factor to make motor work in high efficient mode.
