Chapter 1 General knowledge of the integrated drive controller
◉ When switching on a elevator integrated drive controller which has
been stored for more than 2 years, a voltage regulator is needed to
supply it by increasing the voltage gradually
Or it may cause risk of electric shock and explosion
◉ Avoid faulty operation when elevator integrated drive controller is
running
Or it may cause risk of high-voltage electric shock.
◉ After it is switched off, the inside of elevator integrated drive
controller may remain dangerous high voltage for a certain period,
don’t open the cover or touch connection terminals
Or it may cause risk of high-voltage electric shock.
◉ Only trained, qualified and authorized person may be allowed to
work on elevator integrated drive controller
Or it may cause risk of electric shock or property damage.
◉ Always remove watches, rings or other metal articles prior to working
and always wear suitable clothes and use appropriate tools when
working on elevator integrated drive controller
Or it may cause risk of electric shock and explosion.
1.6 Operation notice
Please notice the following points when using AS380 series integrated drive controller.
1.6.1 Brake resistor selection
Elevator feature potential energy load, four quadrants movements‘ characteristic,
and the occurrence of power-generation by braking. Therefore, users should consider adding brake
component to the integrated drive controller. Otherwise, tripping may be caused with overvoltage
fault. AS380 series integrated drive controller is equipped with brake unit, so only external brake
resistor is required. The specification table 1.1 for external brake resistor of integrated drive
controller
