3.2. Behaviour of switching links with DIGISPEED during switching on or off

Being switched on DIGISPEED gives an overload impulse up to 100V DC to an adjusted time (here
5ms) upon the switching link's coil. By this over-energizing the magnetic field is established in a
quarter of the time and has four times the force for a short time. The overcoming of the spring's force
is done earlier (here at 1ms) and the switching-movemenbt is fginished earlier (in this case at 8ms),
since rthe magnetic force is stronger. For not overloading the switching device, the over-energizing
should be finished at at least the end of the switching movement (here at 5ms).
The switching off is done at the moment of 50ms. without flywheeling iode the flywheelingcurrent is set
to -56V DC by the DIGISPEED. This enables de-establishing the magnetic force very quickly. At 53ms
the spring's power has allready overcome the magnetic force so that the switching off movement can
be initialized. At 67ms it is allready finished.
Important: To use the reguzlated flywheeling-circle's effects every connected relais or switching link
has to be used without flywheeling diod!! The flywheeling current is set to -56V DC
constantly and can not be externally changed. A further increase of flywheeling current
does not lead to better results in most cases.
