Introduction
Compared with the 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 and three-phase 690 V.
2) 'LYHUVL¿HGFRQWUROPRGHV
It supports sensorless vector control (SVC), closed-loop vector control (CLVC), V/F
control and V/F separation control.

input (PT100, PT1000) thereby providing motor overheat
protection.
Fast current limit
It helps to avoid frequent occurrence of overcurrent faults
of the AC drive.
Multi-motor switchover
Two motors can be switched over via two groups of motor
parameters.
