2.2 Current supply of the SEC-ST
Fig. 2/2:
For rated output in the swivel arm application range a power
unit with 48 V DC (SVG-SEC-48-6) is required. The SEC-ST can
also be operated with 24 V DC. Losses in the dynamics of the
stepper motors must be taken into account here (see data
sheet for the stepper motors).
Please note:
By the use of PELV power units, protection against electric
shock (protection against direct and indirect contact) is
guaranteed with the Festo controllers in accordance with
EN 60204-1/IEC 204. Safety transformers with the adjacent
symbol must be used for supplying PELV networks. The con-
trollers must be earthed to ensure that they function correctly
(e.g. EMC).
