CONVO was the previous brand which was purchased by BOSCH REXROTH
Then we create CANWORLD at 2010 for all industrial areas need
VFD(variable frequency drive).
From 2014, we are focusing on international market and helping more
and more dealers to get and develop their share of market.
Now CANWORLD is designing 4G VFD system based on cloud and mobile

|Magnetic braking||For occasions which have the request of fast stop or regenerative|
loads, the function of magnetic braking can be used. The function
can avoid frequent protection due to over voltage.
|CBC current limiting||The function of CBC current limiting is to minimize the fault of
current and keep the normal running of the AC drive.
|Overcurrent and overvoltage control||The function is to restrict the current and voltage automatically|
during running and avoid the frequent fault protection of over
current and over voltage.
|Special Functions||The delay time of terminals||The user can set the delay time for digital input terminals,
digital output terminals and relays.The time range is 0.0s to

|Multiple speed and simple PLC||Based on built-in PLC or digital input terminals, realize the|
running of sixteen segments speed.
|Two PID inside the parameters||As common PID, the closed-loop system of process control can be
|Fixed length and count||The AC drive can count the pulse signal of 0 to 100K Hz and realize|
the control of count reaching by using digital output terminals.The
drive can also convert the count into length for display and
|Spinning and swing frequency||The fixed swing magnitude, fixed mutations and fixed periodic
output can be achieved at arbitrary frequency.|
|Timing control||Time range: 0 to 65000 hours.|
The timing control can stop the AC drive.
|Power loss ride through||When the power loss ride through happens, by decreasing the running
frequency, the feedback energy of the load can compensate the
voltage drop of the DC bus. As a result, the AC drive can keep
running for a short time.|
|Peripheral terminals||Reference power||10V/30mA.|
Usually, it is used for the power supply of analog input signals.
|Control power||24V/200mA.Usually, it is used for the power supply of digital input
and output terminals.|
|Analog input||Two analog input terminals, which have two types of voltage input
and current input.|
Every input terminal can support three types input signals: 0 to
10V, 0 to 20mA and -10V to 10V.
These two analog input terminals are programmable.
|Analog output||Two analog output terminals, which have two types of voltage output
and current output.|
Every output terminal can support two types output signals: 0 to
10V and 0 to 20mA.
These two analog output terminals are programmable.
|Digital input||Six multi function digital input terminals are compatible with
active PNP or NPN input mode. Among these six input terminals, the
X6 terminal can be chosen as high-speed pulse input terminal and
the range of the high-speed pulse is 0 to 100KHz. At the same time,
the X6 terminal is programmable.|
|Digital output||There are two open collect output terminals. Among them, Y2
terminal can be chosen as high-speed pulse output. These two output
terminals are programmable.There are two relay output terminals.|

|Environment||Installation location||Indoor, free from direct sunlight, dust,drip, salt, oil smoke,
water vapor, combustible gas and corrosive gas.|
|Altitude||If the altitude is equal or lower than 1000 meters, the AC drive
can be used normally.|
If the altitude is higher than 1000 meters, it is necessary to
de-rate the AC drive. The ratio of derating the AC drive is 1
percent for every increase of 100 meters.
If the altitude is higher than 3000 meters, please contact our
