Introduction
Compared with MD320, the MD380 series AC drive incorporates the following improvements:
1) Multiple voltage classes
It provides coverage of single-phase 220 V, three-phase 220 V, three-phase 380 V,
three-phase 480 V, three-phase 690 V and three-phase 1,140 V.
2) Control of asynchronous motor and PMSM
It supports vector control of three-phase AC asynchronous motor and three-phase AC
PMSM.
3) Diversi¿ed control modes

better low-speed stability, enhanced low-frequency loading capacity, and supports
torque control.
7) User programmable function
The MD38PC1 programmable card enables you to write programs in ladder diagram.
Its programming environment is compatible with that of the H1U series PLC.
8) Advanced background software
The background monitoring software helps to achieve functions of parameter upload &
download and a real-time oscilloscope.
9) Other new functions
The newly added functions of the MD380 series AC drive are described as below:
)unction Description
Vi
rtual I/O It can implement various simple logic functions.
Motor overheat protection
The optional MD38IO1 extension card enables AI3 to
receive the signal from the motor temperature sensor
input (PT100, PT1000) thereby providing motor overheat
protection.
Rapid current limit
It helps to avoid frequent occurrence of overcurrent faults
of the A
C drive.
