similar product made by other companies, which improves the product's reliability
noticeably;Without PG connector, strong speed control, flexible input/output terminal, pulse
frequency setting, saving parameters at power outage and stop, frequency setting channel, master and
slave frequency control and so on, all these satisfy various of high accuracy and complex drive
command, at the same time we provide the OEM customer high integration total solution, it values
highly in system cost saving and improving the system reliability.
CV20 can satisfy the customers' requirements on low noise and EMI by using optimized PWM
technology and EMC design.
This manual provides information on installation, wiring, parameters setting, trouble-shooting,
and daily maintenance. To ensure the correct installation and operation of CV20, please read this
manual carefully before starting the drive and keep it in a proper place and to the right person.
Unpacking Inspection Note
Upon unpacking, please check for:

Any damage occurred during transportation;


Wiring:
Danger
-Wiring can only be done after the drive's AC power is disconnected, all the LEDs on the operation
panel are off and waiting for at least 5 minutes. Then, you can remove the panel.
Motor power
-Wiring job can only be done after confirming the charge indicator on the right bottom is off and the
（kW）
voltage between main circuit power terminals + and - is below DC36V.
0.2
-Wire connections can only be done by trained and authorized person
0.4
-Check the wiring carefully before connecting emergency stop or safety circuits.
0.75
-Check the drive's voltage level before supplying power to it, otherwise human injuries or equipment
0.4
damage may happen.
0.75
!
1.5
Attention
0.75
-Check whether the Variable Speed Drive's rated input voltage is in compliant with the AC supply
1.5
voltage before using.
2.2
-Dielectric strength test of the drive has been done in factory, so you need not do it again.
-Refer to chapter 2 on connected braking resistor or braking kit.
-It is prohibited to connect the AC supply cables to the drive's terminals U, V and W.
-Grounding cables should be copper cables with section area bigger than 3.5mm2, and the grounding
resistance should be less than 10Ω.
-There is leakage current inside the drive. The total leakage current is greater than 3.5mA, depending
on the usage conditions. To ensure safety, both the drive and the motor should be grounded, and a
leakage current protector (RCD) should be installed. It is recommended to choose B type RCD and
set the leakage current at 300mA.
-The drive should be connected to the AC supply via a circuit breaker or fuse to provide convenience
to input over-current protection and maintenance.
