ARIS inte­gra­tes a fail-safe modu­le with direct cur­rent dri­ves of the Nano + series

Sin­ce the posi­tio­n­ing of an actua­tor to a safe­ty posi­ti­on in com­plex sys­tems beco­mes increa­singly important in the event of a power fail­u­re, ARIS Stell­an­trie­be GmbH offers a fail-safe ver­si­on for clas­sic actua­tors of the Nano-DC series. In order to ensu­re rapid rege­ne­ra­ti­on after the safe­ty func­tion has been activa­ted, a bat­te­ry solu­ti­on has been exclu­ded from the out­set.

The ARIS deve­l­oper team opted for com­pact ener­gy sto­ra­ge units, which are ful­ly char­ged again after a com­ple­te dischar­ge by repeated, suc­ces­si­ve trig­ge­ring after a maxi­mum of two minu­tes. Thus the necessa­ry 100% safe­ty is ensu­red. Custo­mer sur­veys on the requi­re­ments very quick­ly led to the rea­li­za­ti­on that an exter­nal solu­ti­on is not an effec­tive one. For this rea­son, the ener­gy sto­ra­ge devices with the asso­cia­ted elec­tro­nics are inte­gra­ted into the dri­ve hou­sing.

The ARIS custo­mer can deci­de whe­ther his actua­tor moves at the nor­mal or maxi­mum speed in the end posi­ti­on by means of dif­fe­rent con­nec­tion pos­si­bi­li­ties. Via the pos­si­ble inte­gra­ti­on of addi­tio­nal posi­ti­on swit­ches into the cir­cuit, even inter­me­dia­te posi­ti­ons can be defi­ned as a fail-safe posi­ti­on. This means that the ARIS actua­tors offer a very fle­xi­ble and relia­ble sys­tem.
