Chapter 1 Overview
1.1 Safety requirement and cautions
Please do totally understand this part before using the inverter.
Warning signs and meanings
This manual has used following signs which means there is an important part of security. While observing against the
rules, there is a danger of injury even death or machine system damage.
Danger: Wrong operation may cause death or large accident.
Caution: Wrong operation may cause minor wound.
Operation requirement
Only professionally trained persons can be allowed to operate the equipment. “Professional trained persons “means
the workers must have experience professional trained skill, and must be familiar with installation, wiring, running and
maintain and can rightly deal with emergency cases in use.
Safety guidance
Warning signs come for your security. They are measures to prevent the operator and machine system from damage.
Please carefully read this manual before using and strictly observe the regulations and warning signs while operating.
●Correct transportation, store, installation, careful operation and maintenance are important for inverter safe operation.
In transport and store process, make sure the inverter is free from impact and vibration. It must be stored where is dry
without corrosive air and conductive dust, and the temperature must be lower than 60℃.
● This product carries dangerous voltage and controls driver machine with potential danger. If you don’t abide by the
regulations or requirements in this manual, there is danger of body injury even death and machine system damage.
● Do not wire while the power is connected. Otherwise, there is danger of death for electric shock. Before wiring,
inspection and maintenance, please cut off power supply of all related equipment’s and ensure main DC voltage in
safe range. And please operate it after 5 mins.
● Power wire, motor wire and control wire should be all connected firmly. Earth must be reliable and earth resistance
must be lower than 10Ω.
● Human body electrostatic will damage inner sensitive components seriously. Before operation, please follow ESD
measures. Otherwise, there is danger of inverter damage.
● Inverter output voltage is pulse wave. If components such as capacitor which 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).
● No matter where the fault is, there is danger of serious accident. So there must be additional external prevent
measures or other safety devices.
●Only used in application fields as maker stated. No use in equipments related to special fields such as emergency,
succor, ship, medical treatment, aviation, nuclear and etc.
● Only Veichi Electric co., ltd service department or its authorized service center can maintain the products. It may
cause product fault while using accessories not authorized or permitted. Any defective components must be
changed in time in maintenance.

1.4 Product Features
1. Special VFD for lifting: high working efficiency, fast response, good speed regulation performance, stable
operation, no impact and high safety factor.
2. Stall protection function (closed-loop mode): When the actual speed is detected to exceed 115% of the rated
speed during operation, the frequency inverter signal sends a brake signal to achieve emergency braking.
3. Anti-slip protection function (closed loop mode): In the closed loop mode, when the inverter is energized in the
standby state, when the motor is detected to rotate, the function is activated immediately, and the inverter is locked at
the zero speed output, which provides the system operation. It has maximum security.
4. Zero servo hover function (closed loop mode): that is, at zero speed, keeping the brake open and keeping the
lifting mechanism hovering in the air.
5. Full-range torque monitoring function: Torque monitoring during operation, when the torque output is detected,
immediately block the output and achieve emergency stop.
6. Remote monitoring module (extension): realizes remote positioning, online monitoring, remote fault diagnosis
and other functions of mechanical equipment; provides customers with a wider range of value-added services.
7. Light-load high-speed function: When running in the light load or empty hook state, the frequency is
automatically increased (constant power zone) through the built-in load measurement mode calculation, effectively
improving the working efficiency of the lifting machine by 10% to 50%.
8. Output abnormal protection: torque monitoring during operation, when the torque output is detected or no load,
immediately block the output and achieve emergency stop.
9. The rotary operation is stable: the low-speed operation is smooth and coherent, there is no stop-and-go
phenomenon, the gear position is stable, the boom is continuous and smooth, and there is no “pause” phenomenon.
10. Rotary eddy current control: The built-in eddy current controller adopts PWM pulse width modulation to adjust
the output voltage duty ratio in real time according to the operating frequency, which is superior to the traditional eddy
current voltage regulation module.
11. Flexible torque control (slewing): The “soft belt” is powerful and fast, and the boom does not rebound smoothly.
12. Anti-sway function (variable): The swing is limited by dynamically adjusting the frequency of the inverter and the
acceleration/deceleration time. When the object reaches the set speed, the swing is small or basically stops when it
stops.
13. Special brake logic control: realize the special brake logic control through the release frequency, release current,
AC70T Crane Purpose VFD Manual

brake release time, brake holding time, etc., to ensure the system is safe and reliable.
14. Brake timing description: When the brake is not energized, it is in the state of holding the brake, and must be
released under the condition that the brake is energized; through the release frequency, release current, brake
release time, brake holding brake Time, etc., to achieve a dedicated brake logic control to ensure that the system is
safe and reliable to avoid slipping.

Note: 1.When installing DC reactor, make sure to dismantle the short connector between terminal P1 and（+）.
2.NPN or PNP transistor signal can be selected as input of multi-function input terminal（X1~X7/PUL）.
Inverter built-in power supply (+24V terminal) or external power supply (PLC terminal) can be chosen as
bias voltage. Factory setting ‘+24V’ short connect with ‘PLC’.
3. Analog monitor output is the special output for meters such as frequency meter, current meter and voltage
meter. It can’t be used for control operations such as feedback control.
