Speed ref Total speed reference value in rpm
Speed reg output Output value of the speed regulator, used as the reference value for the current regulator

! The speed regulator is still active even if disabled (Enable spd reg = Disabled),
therefore the Speed reg output contains valid information also in this case.
Such a data can be transferred to the 6KCV300DGF board to be used for other
regulation. If the speed regulator is enabled (Enable spd reg = Enabled) the
Speed reg output contains the sum of the actual speed regulator output and
T current ref 2.
Lock speed reg This parameter is used in order to lock the speed regulator. When this happens, it stops to
work, the current reference value is set to zero and the drive comes to a stop. This coast-
ing time then depends on the rotating mass and the friction within the system concerned.
If the connection between the speed regulator and the current regulator is restored, the
drive will restart in the shortest possible time.
ON Speed regulator locked (= 0 V when using a digital input).
OFF Speed regulator unlocked (= 15...30 V when using a digital input).
Enable spd reg This parameter can only be changed when the drive is switched off.
Enabled The speed regulator is enabled. The regulator output is connected
to the input of the current regulator. Speed reg output = T cur-
rent ref 1
Disabled The speed regulator is disabled.
