Safety Precautions
Please pay close attention to all safety-related information in this user manual; otherwise there may be
fatal consequences. Please note the manufacturer shall bear no liabilities to damages of any sorts
resulting from false operations which is not following this user manual.
Warning ---- potential risks. Fatality may be caused if not avoided.
Attentions – please follow these instructions when using the inverter.
Do not do wiring operations at power on;
Only qualified electrical engineers can install & maintain the inverter;
Power on the inverter only after the covers have been put back on. Do not remove the cover during
power on;
Please wait at least 10 minutes after power of to remove the cover; so as to let DC bus capacitors to
fully discharge;

may be risks of fire;
Please do not operate the inverter with wet hands. The inverter has many semiconductor components
inside;
The inverter is not designed for voltage-withstanding tests;
Do not alter the inverter;
Do not install or use any inverter which is already broken or with faulty parts.
Attentions – when scrapping the inverter.
Electrolytic capacitors on the PCBs of the inverters may explode if incinerated;
Poisonous gas may emit if incinerated;
Please dispose scrapped inverters as industrial waste.
WARNING
Risk of electric shock!
Wait at least 10 minutes after power off to remove the cover.

2.3.2 Control circuit wiring notes
Analog input wirings
As analog signals can be easily affected by external interference, shielded cables shall be used. Cables
shall be as short as possible and not exceeding 20 meters. As shown in graphs below, in some severe
circumstances, filter capacitor or ferrite bread shall be used in analog signal side.
Digital input wirings
Shielded cables shall be used. Cables shall be as short as possible and not exceeding 20 meters. When
using active drive mode, user shall take necessary filter measures to counter power interference. It is
recommended to use node control mode. Digital inputs can be NPN or PNP.
NPN input: Most common. Use
internal 24V power; +24V terminal short-
circuit with SP terminal; COM terminal
is common; J9 is 23 jumped; also known
as drain wiring mode.

J9 is 12 jumped; also known as source
wiring mode.
Output wirings
Digital output is open collector output. When using external power, please connect external power
negative node to COM terminal. Maximum current is 50mA for open collector output. If external load is
relay, please install fly-wheel diode to both ends of the relay.
Note: please install fly-wheel diode
polar correctly, otherwise internal
components will be damaged.

3.2 Parameter setting example
DLA1 inverter panel has a three-level structure: function code group (level 1menu) → function code
(level 2 menu) → function code setting (level 3 menu).
Example: Change P2.02 from 10.00Hz to15.00Hz, as shown in graph below:
Parameter monitoring: please refer to P7.03, P7.04, P7.05 for parameter monitoring settings.
Password setting: when PP.00 is not 0, inverter is under password protection. The password is as
shown in PP.00. To cancel password protection, user must enter the correct password and set PP.00=0.
3.3 Motor parameter auto-tuning
1) Set P0.02=0 (keyboard as command source channel)
2) Input motor parameters:
Motor selection
Parameters
Motor 1
P1.00: motor type selection; P1.01: rated power
P1.02: rated voltage; P1.03: rated current
P1.04: rated frequency; P1.05: rated speed
3) If (asynchronous) motor can separate from load, set P1.37=2 (asynchronous motor complete
auto-tuning) and press RUN key. The inverter will automatically calculate parameters below:
Motor selection
Parameters
Motor 1
P1.06: asynchronous motor stator resistor
P1.07: asynchronous motor rotor resistor
P1.08: asynchronous motor leakage inductance
