Description

ADrive Speed Control Units

ADrive GENERAL FEATURES ADrive Can be used with asynchronous (geared) and synchronous (gearless) lift drives. Provides great travel comfort. Can be used with asynchronous (geared) and synchronous (gearless) lift drives. Provides great travel comfort. Load-independent and sensitive stopping on the floors. High torque motor drive at all speed via space vector modulation. Up to 40% electrical usage savings. Elimination of startup problems with generators with the help of controlled motor current. Specifically designed for elevators. Special parameters for traveling comfort. 10 KHz IPM switching frequency for low noise motor drive. Energy consumption through an internal DC reactor. 4 low noise fans for efficient cooling. All isolated control inputs and outputs. Over-load, high voltage, low voltage, output short circuit, power lost, line phase control, overheat, ground fault, over-torque and other necessary protection functions. EMC tested and verified. 5.5 kW, 7.5 kW, 11 kW, 15 kW and 22 kW power rating models.
