30 Operation principle and hardware description
Operation principle
The ACL30 elevator drive is a wall or cabinet mountable drive for controlling an
asynchronous motor or a permanent magnet motor. The following components define
the operation of the drive. See the main circuit on page
Main circuit
Component
Description
Rectifier
Converts the three-phase AC voltage to DC voltage.
Capacitor bank
Stores energy which stabilizes the intermediate circuit DC voltage.
Drive
Converts DC voltage to AC voltage and vice versa. The motor is controlled
by switching the IGBTs of the drive.
Brake chopper
Conducts the energy generated by a decelerating motor from the DC bus to
a braking resistor. The brake chopper is built in the ACL30. Brake resistors
are external options.
Brake resistor
Dissipates the regenerative energy by converting it to heat.
Mains choke
Reduces
• harmonics and r.m.s in the input current
• supply disturbance and low-frequency interference.
Mains filter
