Preface
Thank you for purchasing the MD380 series AC drive developed by Shenzhen Inovance
Technology Co., Ltd.
The MD380 series AC drive is a general-purpose high-performance current vector control
AC drive. It is an upgrade product based on MD320 and can implement the control of
asynchronous motor and permanent magnet synchronous motor (PMSM). It increases the
user programmable function, background monitoring software and communication bus
function, and supports multi-kind PG cards. It is used to drive various automation production
equipment involving textile, paper-making, wiredrawing, machine tool, packing, food, fan
and pump.
This manual describes the correct use of the MD380 series AC drive, including selection,
parameter setting, commissioning, maintenance & inspection. Read and understand the
manual before use and forward the manual to the end user.

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
Virtual 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 AC drive.

)unction Description
Multi-motor switchover )our motors can be switched over via four groups of
motor parameters.
Restoring user parameters It allows you to save or restore the parameters set by
yourself.
Higher-accuracy AI/AO The AI/AO accuracy can reach almost 20 mv via factory
correction or on-site correction.
Customized parameter
display You can customize the parameters that need to be
displayed.
Modi¿ed parameter display You can view the modi¿ed parameters.
Operation selection at fault
occurrence
You can select the reaction of the AC drive to a fault
occurring, based on the actual need. The reactions are as
below:
Coast to stop
Decelerate to stop
Continue to run
You can also select the frequency at which the AC drive
continues to run.
PID parameters switchover Two groups of PID parameters can be switched over via terminals or can be automatically switched over according
to deviation.
PID feedback loss detection The PID feedback loss value can be set to realize PID
protection.
DI/DO positive or negative
logic You can set the DI/DO positive or negative logic.
DI/DO response delay You can set DI/DO response delay time.
Power dip ride through It ensures that the AC drive continues to run for a short time when an instantaneous power failure or sudden
voltage reduction occurs.
Timing operation The AC drive supports timing operation for 6500 minutes
at maximum.
User programmable function The externally connected programmable card helps you
to realize secondary development.
Load allocation Load allocation can be implemented between two MD380
series AC drives through point-to-point communication.
