B&R's compact motor-mounted drives save machine building costs

The new devices cover a power range up to 0.35kW, and the smallest version measures just 60mm × 90mm (w × h). Despite their compact dimensions, they have a full-fledged integrated servo drive that enables control loops as fast as 50us. They are optionally available with an integrated gearbox and brake.

These 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 on via daisy-chain cabling. The 300 degree swivel connections also facilitate easy installation. The time and cost of cabling are reduced significantly.

B&R's new ACOPOSmotor variants have a wide voltage range of 24 to 60V DC. Thanks to the low voltage, no special training is necessary in order to exchange devices. It is also possible to feed regenerative braking energy back into the DC bus. This can reduce energy consumption by up to 30 per cent.

The STO safety function comes standard on motor-mounted drives. It is 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. It offers IP65 protection and requires neither fans nor heat sinks.
