improves power factor and pressure-sensitive resistance for anti-thunder and
so on are installed at the output side, please dismantle them or change to input
side.
●No switch components such as breaker and contactor at the output side. (If
there must be one, please make sure the output current is 0 while the switch
acting).
●Run regulation
●Inverter runs at high voltage. So dangerous voltage is in some components
inevitably.
●No matter where the fault is, there is danger of serious accident, even human
body injury what means dangerous malfunction possibility. So there must be
additional external prevent measures or other safety devices, such as
independent current limiting switch, machinery fense and so on.
●In order to guarantee the right action of the motor’s overload protection, the
input parameters of motor to the inverter must be must be in full compliance
with the actual used motor.

service center or professional person trained and authorized by Veichi can
maintain the products. They should be very familiar with the safety warning
and operation gist in this manual.
●Any defective components must be changed in time.
●Before opening the inverter to repair please cut power supply of all related
equipments and ensure mains DC voltage in safe range. And please do
operation after 5 mins.
●Dismantlement and disposal regulation
●Packing case can be reused. Please keep them and reuse or send back to
maker.
●Dismantled metal components are retractable and can be reused.
●Some components such as electrolytic capacitor are harmful to environment.
Please dispose accronding to environmental protection departments.

1.3 Product Features
Tower crane lifting purpose frequency inverter: high working efficiency, fast response,
good speed performance, smooth operation, no impact and high safety factor.
1. Stall protection function (closed-loop mode)
When the actual speed exceeds 115% of the rated speed, the frequency inverter sends brake
signal to realize emergency braking.
2. Anti-slip hook protection
In closed-loop mode, when the frequency inverter is power on in the standby mode, activate the
function immediately if the motor rotation is detected at this time. Frequency inverter, locked to
zero speed output, has provided the greatest safeguard for the system safe movement.
3. Light load automatic speed up function (weak magnetic speed)
Automatic high-speed lifting when tower crane is under light load (below 30% of rated load) or
empty hook, greatly improves the work efficiency.
4. Special logic brake control function
Through the brake frequency, release current, brake release time, brake closing time, to achieve
special logic brake control, to ensure system safety and reliability.
Tower crane slewing purpose frequency inverter: strong load capacity, smooth start
without shaking, fast and efficient in-place, more reliable performance.
1. One-way PWM pulse output signal provided to the eddy current controller, so that the arm is
smooth and reliable without shaking when braking.
2. Built-in anti-swing function: easy hook, effectively improves working efficiency.
3. Strong jog, stable arm without shaking, high-speed shutdown, accurate in place.
Tower crane luffing purpose frequency inverter: high efficiency, smooth running,
good speed performance, accurate positioning, reliable performance.
Built-in anti-swing function: by adjusting the speed and dynamic adjustment in acceleration
and deceleration time to limit objects’ swing.
The braking unit of traditional frequency inverter has no short-circuit protection while
Veichi tower crane purpose frequency inverter has built-in braking unit with braking
resistor short-circuit protection.
Special GPS/GPRS communication port.
GPS/GPRS communication port for satellite positioning and remote monitoring (construction
machinery information management platform). Remote lock and unlock function, easy for
installment customer management (with special GPS module).
