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 6
th
generation of module with the junction temperature resistance up to
175℃. Low loss for switch and connection to ensure the long use life.
