Variable-speed drives used in motor-driven applications must
contain certain safety features in order to protect users and equipment whilst
complying with BS EN 60204-1 – the British standard for Electrical Machinery
Safety.
Safe torque off (STO) is one such feature and comes built in
as standard with ABB drives. STO is used to bring a drive to a no-torque state
which prevents unexpected start-up. In the case of an emergency stop, STO will
cut off the drive output to the electric motor, allowing it to slow smoothly
and safely to a standstill. Typical applications that benefit from STO include
conveyors, mixers and grinding mills.
We’re well aware that safety is paramount in industry, and
as an ABB Authorised Value Provider we can recommend suitable drives and
software to help users manage risks on site. For all ABB drives enquiries
please call Paul Scott on 01621 868138 or email paul@gibbonsgroup.co.uk.
