4.5.11 Signal definitions
Signal "At Set Point"
Speed reference reached.
Speed actual value
Speed Act (5.05) correspondes
to speed reference value before ramp generator
Ramp In Act (5.33) . The deviation between both is
less than ±1,56% (1/64) of parameter maximum speed
Max Speed (1.06) . Signal At Set Point is independent
on ON and RUN command.
Signals "Speed > Lev1“ / „Speed > Lev2“
Speed Level reached. Speed actual value Speed Act
(5.05) is equal or greater than value of parameter
Speed Level 1 / 2 (5.16 / 5.17) . The permitted
hysteresis is -0,78% (1/128) of parameter Max Speed
(1.06) . That means during rising speed the threshold
is exactly the value of Speed Level 1 / 2 (5.16 / 5.17) ,
during falling speed the threshold is Speed Level 1 /
2 (5.16 / 5.17) – 0,78% . Signals Speed > Lev1 /
Speed > Lev2 are independent on ON and RUN
command.

Signal "Comm Fault"
If Cmd Location (2.02) = Bus the drive will trip in case
of fault F20- Communication Fault and will stop in
accordance to Comm Fault Mode (2.07) . If Cmd
Location (2.02) = Makro depend or Terminals or
Key only an alarm A11-Comm Interrupt will be
shown and the drive will not trip.
