Preface
Thank you for purchasing the MD380 series AC drive developed by Inovance.
The MD380 series AC drive is a general-purpose high-performance current vector control AC
drive and is mainly used to control and regulate the speed of three-phase AC asynchronous
motor. It adopts advanced vector control technology and has low-speed high-torque output,
good dynamc feature and strong overload capacity. 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. Before using the AC drive,
read this manual carefully to have a thorough understanding of the product. Keep the
manual well and forward it with the product to end users.

Do not repair or maintain the AC drive at power-on. Failure to
comply will result in electric shock.
Repair or maintain the AC drive at least ten minutes after the
AC drive is powered off. This allows for the residual voltage in
the capacitor to discharge to a safe value. Failure to comply will
result in personal injury.
Ensure that the AC drive is disconnected from all power supplies
before starting the repair or maintenance work.
All the pluggable components must be plugged or removed only
after power-off.
Set and check the parameters again after the AC drive is
replaced.
WARNING
The rotating motor generally feeds back power to the AC drive.
As a result, the AC drive is still energized even if the motor
stops, and the power supply is cut off. Thus ensure that the AC
drive is completely disconnected from the motor before starting
the repair or maintenance work.

transient and steady-state leakage current to ground that may be generated at startup
and during running of the AC drive. You can select a specialized RCD with the function
of suppressing high harmonics or a general-purpose RCD with relatively large residual
current.

2) Motor insulation test
Perform the insulation test when the motor is used for the first time, or reused
after being stored for a long time, or in a regular check-up, in order to prevent the
poor insulation of motor windings from damaging the AC drive. The motor must be

3) Thermal protection of motor
If the rated capacity of the motor selected does not match that of the AC drive,
especially when the AC drive's rated power is greater than that of the motor, adjust the
motor protection parameters on the operation panel of the AC drive or install a thermal
relay for the motor for protection.

5) Vibration of mechanical device
The AC drive may encounter the mechanical resonance point at certain output
frequencies, which can be avoided by setting the frequency jump parameters of the AC
drive.
6) Motor heat and noise

Do not change three-phase input of the AC drive into two-phase input because this will
cause faults or damage the AC drive.

MD380 User Manual Safety Information and Precautions

11) Surge suppressor
The AC drive has a built-in voltage dependent resistor (VDR) for suppressing the surge
voltage generated when the inductive loads (electromagnetic contactor, electromagnetic
relay, solenoid valve, electromagnetic coil and electromagnetic brake) around the AC
drive are switched on or off. If the inductive loads generate a very high surge voltage,
use a surge suppressor for the inductive load or or use a surge suppressor together
with a diode.
Note
Do not connect the surge suppressor on the output side of the AC.
12) Altitude and de-rating
In places where the altitude is above 1000 m, the cooling effect reduces due to thin air,
and it is necessary to de-rate the AC drive. Contact the agent or Inovance for technical
support.
13) Special usage
If wiring that is not described in this manual, such as common DC bus is applied,
contact the agent or Inovance for technical support.
14) Disposal
The electrolytic capacitors on the main circuits and PCB may explode when they are
burnt. Poisonous gas is generated when the plastic parts are burnt. Treat them as
ordinary industrial waste.
15) Adaptable Motor
 The standard adaptable motor is four-pole squirrel-cage asynchronous induction
motor. For other types of motors, select a proper AC drive according to the rated
motor current.
 The cooling fan and rotor shaft of a non-variable-frequency motor are coaxial, and
the cooling effect of the fan degrades when the motor speed reduces. Therefore,
add a more powerful fan or replace the motor with a variable-frequency motor in
scenarios where the motor overheats easily.

performance will be affected.
 The AC drive may alarm or even be damaged when short-circuit exists on cables
or inside the motor. Therefore, perform the insulation short-circuit test when the
motor and cables are newly installed or during routine maintenance. During the
test, make sure that the AC drive is completely disconnected from the tested parts.
