5.6.21 Connecting the tightening tool and using the "SpDck" PLC signal
(1) Input, (2) Output
The SpDk signal may only be set from "high" to "low" immediately a f t e r the plug and socket device
has been connected! This switches on the supply voltage to the spindle (prevention of contact burning).
After a maximum of 3 s, the system is ready for the next tightening operation. This is signaled by the fact
that SpDckAck is set to "low" and the Rdy and NF signals are set to "high".
