Preface
EC 6 70
V1.0
Thank you for using the EC670 Solar Pump AC drive. This AC drive is a
special AC drive made by our company for PV water supply industry, and it
is also suitable for other basic applications.
Please carefully read this manual before the installation in order to
ensure the correct installation and operation of the AC drive, give full play
to its superior performance, and ensure safety. Please keep this guide per-
manently for future maintenance, service and overhaul.
AC drive is a precise electric and electronic product, thus for the
safety of the operators and the equipment, please ensure that the installa-
tion and parameters adjustment is done by professional motor engineers and
the content marked as “Danger”,“Notice”, etc in this manual must be read
carefully. If you have any questions, please contact with the agents of our
company, and our technicians are ready to serve you.
The instructions are subject to change, without notice.
You can contact us with any product questions through the following ways.
1.P r ef a ce
Dangerous and wrong use may cause casualties
Danger
●The power supply must be turned off when laying the wires.
●When the AC power supply is cut off but the indicator light of the mani-
pulator of AC drive is still on, there is still high voltage in the AC
drive which is very dangerous, please do not touch the interior circuit and
components.
●Do not check the components and signals on the circuit board during
operation.
●The terminal of AC drive must be grounded correctly.
●Do not refit or replace the control board and parts without permission,
otherwise, there are risks such as electric shock and explosion.
！Wrong use may cause damage to AC drive or mechanical system
！Notice
●Please do not test the voltage resistance of the interior components of AC
drive, as the semiconductor of AC drive is easy to be punctured and damaged
by high voltage.
●Never connect the main circuit output terminals U, V, and W directly to
the AC main circuit
power supply.
●The circuit board of the AC drive has CMOS IC which is extremely easy to
be damaged by static electricity, thus please do not touch the circuit board
with your hand before taking anti-static electricity measures.
●Only the qualified motor professionals can install the driver, lay the wire,
repair and maintain the AC drive.
●The scrapping of AC drive shall be treated as industrial waste and burning
is strictly prohibited.

Multi segment instructions can be used in
three situations:
As frequency source, voltage source sepa-
rated from VF and setting source of pro-
cess PID
As a frequency source, it is the percen-
tage of relative maximum frequency:
As a VF separated voltage source, it is
the percentage of rated voltage relative
to the motor;
As a PID given, it is originally a rela-
tive value, and as a PID set source, it
does not need dimensional conversion.
Multi segment instructions need to be se-
lected according to different states of
multi-functional digital S. please refer
to P4 group for details.

It is only valid for vector control
and invalid for VF control. Running
at different frequencies, different
PI parameters of speed loop can be
selected. When the operating frequ-
ency is less than the switching fre-
quency 1, the PI adjustment parame-
ters of the speed loop are p2-01 and
p2-02. When the operating frequency
is greater than the switching frequ-
ency 2, the PI adjustment parameters
of the speed loop are p2-04 and p2-05.
The PI parameters of speed loop bet-
ween switching frequency 1 and swit-
ching frequency 2 are linear swit-
ching of two groups of PI parameters.
By setting the proportional coeffi-
cient and integral time of the speed
regulator, the dynamic response cha-
racteristics of the vector control
can be adjusted. The dynamic response
of the speed loop can be accelerated
by increasing the proportional gain
and reducing the integration time.
However, if the proportional gain is
too large or the integration time is
too small, the system may oscillate.

This parameter is used to filter the torque
command. Generally, there is no need to
adjust. When the speed fluctuates or the
vibration of the motor is large, the filter-

The current loop PI parameter of vector
control can be obtained automatically after
the asynchronous machine is fully tuned or
the synchronous machine is no-load tuned,
which generally does not need to be modified.
If the current loop PI gain setting is too
large, the whole control loop may oscillate.
Therefore, when the current oscillation or
torque fluctuation is large, the PI propor-
tional gain or integral gain can be reduced
manually.
