● Follow the recommended value of cable in this manual,
and select copper conductor of corresponding size!
●The specification and installation of the main circuit wiring
shall comply with local regulations and relevant IEC
standards.
Operation precautions
Danger
● Do not touch any input or output port of the driver and
peripheral circuits, otherwise it may cause electric shock!
●Do not touch the housing of driver to test the temperature,
otherwise it may cause burns!
● After the driver is powered on, do not force to cut off
external high voltage and low voltage power supply. Follow
the normal sequence to power off the whole vehicle and the
driver!
Danger
● Please do not use contactor to control the
start-up and
shut-down of driver, otherwise it may cause
damage to the
equipment!
●Please do not change the manufacturer's parameters at
will, otherwise it may cause damage to the equipment!
1. Product information
The CV800 driver consists of three independent parts, PLC, DC-DC and inverter, and CAN communication network is applied for internal
communication.

Specification
Inverter
Basic
function
Maximum output
frequency
Vector control: 0~500Hz; V/F control: 0~500Hz
Carrier
frequency
0.8kHz~12kHz (
adjust carrier frequency
automatically according to load characteristics
)
Input frequency
resolution
Digital setting: 0.01Hz; simulation setting:
maximum frequency×0.025%
Control mode
SVC open-loop vector control (synchronous
motor); V/F
control (asynchronous motor)
Acceleration and
deceleration
curve
Linear or S curve acceleration and deceleration
mode
.
Four kinds of acceleration and deceleration time,
with range of
0.0~6500.0s
Automatic
voltage
adjustment
(AVR)
When the grid voltage changes, the output voltage
can be maintained constant automatically
Overvoltage and
overcurrent stall
control
The current and voltage are automatically restricted
during the operation, preventing frequent tripping
due to overcurrent or overvoltage
Fast current
limiting function
Minimize
overcurrent failure and ensure normal
operation of inverter
Torque limitation
and control
With "excavator" features,
it automatically restrict
torque during operation, preventing frequent
tripping due to overcurrent
;
the closed-loop vector
model may be applied for torque control
Powerful
background
software
Support inverter parameter operation and virtual
oscilloscope function
s
The virtual oscilloscope can be used for graphical
monitoring of the internal state of inverter
Operation
Frequency
source
Operation panel setting, control terminal setting,
and serial communication port setting can be
switched in many ways
Frequency
source
Five frequency sources: digital setting, analog
voltage setting, analog current setting, pulse setting
and serial port setting that can be switched in many
ways
