AS380 series elevator integrated drive controller is the new generation of state-of-the-art
elevator-specific control and drive device. With full consideration of the safety & reliability of
elevator;inherent characteristic of elevator operation and specific feature of potential energy load
for elevator, AS380 series elevator integrated drive controller adopted advanced technology of
frequency control of motor speed and intelligent elevator control as well as the integration of
control & drive of elevator to make the further improvement of the product performance,
easy-to-use property and cost efficiency.
Main features
a) Prefect integration of control and drive of elevator. The whole device features compact
structure and small size, fewer connections, which is characterized as high reliability and
easy-to-use property and cost-efficiency.
b) Double 32-bit embedded microprocessor jointly finish the elevator operation and motor drive
control
c) Redundant safety design , double safety protection for control processor and drive processor
to achieve the maximum safety guarantee for elevator travel
d) The design requirements of anti-interference capacity go beyond the highest standard in the
industrial design requirement.
e) All CAN bus communication make the whole system connected easily, data transmitted
strongly, and more reliable.
f) The adoption of the advanced direct landing technology make elevator running more
efficiently
g) The advanced multifunctional elevator operation mode can fully meet various needs of
customers`
h) Advanced group control feature. Not only compatible with the traditional group control mode
of up to 8 units, but also support the new group control of destination floor distribution.
i) The adoption of advanced vector control technology can make the motor speed adjusted well
for the realization of the best elevator comfort.
j) Adapt to both synchronous motor and asynchronous motor.
k) Newly-developed none-load sensor-activated compensation technology provides excellent
starting comfort to elevator even if no counterweight is installed.
l) To adopt incremental ABZ encoder to realize the synchronized control of motors. To adopt the
none-load sensor-activated compensation technology to achieve the excellent start-up
comfort.
m) New PWM dead band compensation technology can effectively reduce the motor noise and
loss of machine.
n) Dynamic PWM carrier modulation technology can effectively reduce the motor noise.
o) Auto-tuning phase of synchronous motor without encoder
p) Asynchronous motor is not required for motor parameter acquisition process once the motor
parameter is set correctly. The convenient static motor parameter acquisition process is
available If is impossible to acquire the exact motor parameter on site. So there is no need to
hoist the car and etc in this way.
q) The hardware is the 6th generation of module with the junction temperature resistance up to
175℃. Low loss for switch and connection to ensure the long use life.

Well used submersible pump mainly used two kinds of flooding and oil immersion, are composed of two parts of the pump and motor. In order to ensure the normal operation of the pump, it must be carried out as follows. 1. Electric pump before use, the application of megger to check the motor insulation resistance, the minimum value of not less than 5 megohm. Check the method is to connect a megohmmeter on the electric pump cable terminal block, the other terminal connected to the motor housing, the megger, shake, observe the insulation resistance. 2. Check the cable to crack, abrasion and other phenomena, if damaged should be promptly replaced to prevent leakage. 3. Water immersion motor should open the irrigation bolts, filled with clean water, tighten the bolts, and then dive into the water. Oil immersed motor, such as the discovery of oil spills, seal components should be replaced before diving into the water. 4. Pumping into the water before the pump should be filled with water pump, empty 1-2 minutes, and start 2 times, check idling and start normal. If you turn the opposite, the two-phase wiring can be exchanged. 5. Check whether the crack Yang pipes, the connection is solid. 6. Do not pull the pump when diving into the water or lifting, in order to avoid damage to the cable or the joint at the disconnect. 7. The supply voltage should be controlled within 5% of the rated voltage. If the voltage is too high or too low, the motor will be damaged. 8. Electric pump into the water should be vertical, not diagonal. 9. Pumps shall not be transported more water or mud sediment. Flooding motor should always clean the motor cavity sand, replace the motor cavity of water. 10. The actual pump lift should be within the rated head of 0.8-1. This can improve the efficiency of electric pump, saving, to avoid motor overload operation, extend the service life. 11. After the electric pump, it should be cleaned, coated with anti-rust oil on the metal surface and stored in a dry place vertical. Flooding motor should also be placed within the clean water motor.
