5.6.20 Disconnecting the tightening tool and using the "SpDck" PLC signal
(1) Input, (2) Output
Attention The tightening tool may not be disconnected before the SpDckAck PLC signal is "high"! The waiting time
elapsing from the time when SpDck is set to "high" and the time when SpDckAck changes to "high", is
approx. 3 s. After SpDck has been set to "high", this time is required for lowering the spindle voltage to
values < 0.1 V. This prevents burning of the contacts upon disconnection of the plug and socket device
and in this way considerably extends the service life of the contacts.
