This chapter describes the construction and operating principle of the ACL30 elevator
drive.
Product overview
The ACL30 elevator drive can be used for a wide range of elevator applications, such
as passenger elevators and freight elevators. The same application enables geared
and gearless applications, supporting both synchronous and asynchronous motors.
High elevator control performance is achieved by utilizing the Direct Torque Control
(DTC) technology. Accurate control of speed and torque can be implemented with or
without feedback from the motor shaft.
The drive is available in frame sizes B, C and D depending on the output power. All
frame sizes use the JCU type control unit. The customer can install the drive module
into a cabinet. The drive module has an air-cooled heatsink.
