Two new compact motor-mounted drives from B&R are additions to the ACOPOS motor series and will aid development of modular plants and machinery by reducing installation costs and saving cabinet space.
The new devices cover a power range up to 0.35 kW, and the smallest version measures just 60 mm wide by 90 mm high. Despite their compact dimensions, they have a full-fledged integrated servo drive that enables control loops as fast as 50 µsec. They are optionally available with an integrated gearbox and brake.
The devices have two connections for hybrid cables, so only a single cable is required to connect to the control cabinet. The hybrid cable transmits both the power supply and POWERLINK communication. Additional ACOPOSmotor units are easily added via daisy-chain cabling. The unique 300° swivel connections also facilitate easy installation. The time and cost of cabling are reduced significantly.
The new ACOPOSmotor variants have a wide voltage range of 24 to 60 Vdc. With the low voltage, no special training is necessary in order to exchange devices. It’s also possible to feed regenerative braking energy back into the dc bus, which can reduce energy consumption by up to 30%.
The STO safety function comes standard on motor-mounted drives. It’s controlled via the hybrid cable, so no extra wiring is necessary. Available encoder variants include multi-turn, multi-turn with battery, and single-turn. ACOPOSmotor is designed for use in harsh environments and offers IP65 protection and requires neither fans nor heat sinks.
