Preface
Thank you for purchasing MD021 inverter. The MD021 inverter is
specially designed for wire drawing machine which has high
requirements on installation, commissioning and reliability. In
addition, it can be used as a general purpose inverter when special
functions for wire drawing machine are shielded.
This manual is a guide to the operations of MD021 series inverter.
Please read this manual carefully before performing operations and
keep it properly for future use.
Unpacking and Inspection
Check that the following requirements are met after unpacking the
box:
1) The box contains the equipment and user manual. (operation panel
and operation panel wire are optional parts additional to the standard
configuration).
2) The equipment is packed using a plastic bag. The plastic parts are
intact without damage.
3) The model on the nameplate is the same as your order.

Chapter 1 Safety and Precautions
In this manual, the safety precautions are graded based on the degree
of danger:
: indicates that severe personal injury even death
may result due to improper operation.
: indicates that minor personal injury or equipment
damage may result due to improper operation.
1.1 Precautions for Installation
The temperature of the running environment for the inverter
must be within –10℃to +50℃. The temperature of the
storage environment for the inverter must be within –20℃to
+50℃. In addition, the inverter must be stored with the
original package.
Do not use the damaged inverter or inverter with
missing parts. Otherwise, there may be risk of injury.
Contact the agencies or Inovance.
Mount the inverter on incombustible surface, and keep it

MD021 Plastic Wire Drawing Machine User Manual
away from flammable substances. Otherwise, it may cause
fire.
When more than two inverters are to be installed in
one cabinet, pay attention to the installation locations
(refer to Chapter 3 "Mechanical and Electrical
Installation") to ensure the cooling effect.
Do not drop the lead wire stub or screw into the
inverter. Otherwise, it may damage the inverter.
Correctly connect the input power wires (L, N),
ground wire (PE), and output wires (U, V and W).
Otherwise, it may damage the inverter.
Ensure that the wiring meets the EMC requirements
and the local safety standard. The wire size shall be
determined according to the manual. Otherwise,
accident may occur.
1.2 Precautions for Running
1. Maintenance and repair shall be performed by the professional
engineering technician; otherwise there will be personal injury or

MD021 Plastic Wire Drawing Machine User Manual
damage on to the equipment. Maintenance and repair shall be
performed upon after power off; otherwise, there will be risk of
electric shock may result.
2. Perform insulation test when the motor is used for the first time, or
when it is reused after being stored for a long time, or in a regular
checkup, aiming to prevent the poor insulation of motor windings
from damaging the inverter. The motor must be disconnected from the
inverter during the insulation test. A 500 V mega-ohm meter is
recommended, and the tested insulation resistance must not be less
than 5 MΩ.
3. Perform periodic inspection on the terminals to check that the
screws and wiring terminals are not loose. If they are loose, do the
maintenance.

Installation
3.1 Mechanical Installation
3.1.1 Installation Environment
1) Ensure that the environment is free from direct sunlight, high
humidity and condensation.
2) Install the inverter in the upright direction. If an inverter needs to be
installed above another inverter, install an insulation guide plate to
prevent the lower inverter from heating the upper inverter.
3) Ensure that the installation support are incombustible materials.
Reserve sufficient heat dissipation room if the inverter is installed in a
sealed environment.

DATA: This indicator blinks when data is received.
RUN/ERR: This indicator stays on when the inverter is running, and
blinks when a fault occurs. You can set the indicator to another
function by modifying the function of the DO terminal.
POWER: This indicator is on when the power button is pressed and
the power supply is normal. If the indicator becomes off, it indicates
that the power supply is abnormal or a fault occurs. If the indicator
blinks, it indicates that the wiring of the control circuit may be
abnormal, triggering protection to the inverter.

3.2.2 Description of Wiring Terminals
Terminals at the backside of the inverter are as follows (from top to
the bottom):
1. Communication port (RJ45, supporting RS-485 communication)
2. Control signal terminal (12-pin terminal)
3. Inverter output terminal (4-pin, connecting to the motor)
4. Power input and ground terminals (3-pin connecting to the power
source and the ground)
Descriptions of the terminals are as follows:
Communication port
The communication port can be used as a port for connecting the
external operation panel (use ordinary cable for connection) and
RS-485 communication port for connecting the host computer (use
lead-out cable to transmit signals).
The following diagram shows the signal allocation of the port.

4.2 How to Query and Modify Function Codes
The MD021’s operation panel adopts three-level menu, convenient for
quick querying and modification of parameters.
The three-level menu consists of function code group number (Level
I), function code (Level II), and function code value (Level III),
shown in Figure 4-2:
Figure 4-2 Three-level menu operation flowchart

MD021 Plastic Wire Drawing Machine User Manual
Digit display Level I menu Level II menu Level III menu
Modify the
parameter group Modify the function code Modify the value of the function code
In Level III menu, you can modify parameters by pressing ▲ or ▼.
● After the modification, if you press ENTER, the system saves
parameter setting first, and then goes back to Level II menu and shifts
to the next function code.
● After the modification, if you press PRG, the system does not save
parameter setting, but directly returns to Level II menu and stays at the
current function code.
In Level III menu, if the parameter has no blinking bit, it means that
the parameter cannot be modified. This may be because:
● Such function code is readable parameter, such as actually detected
parameter and running record parameter.
● Such function code cannot be modified in the running state and can
only be changed after the inverter stops.
● Such function code is set after inverter auto-tuning and cannot be
modified.
The methods of displaying the status parameter are as follows:

MD021 Plastic Wire Drawing Machine User Manual
When the inverter is in running or stop state, you can press ►► to
display running state or stop state parameters in turn.
The parameter display sequence when you press ►► in running state
is as follows:
