18.71 Speed set value positive limit
The set value at the speed controller input is limited to this value in the positive range. If
limitation is active, Bit
1 is set in Z108.16– status internal limits.
18.72 Speed set value negative limit
The set value at the speed controller input is limited to this value in the negative range. If
limitation is active, Bit
1 is set in Z108.16– status internal limits.
18.73 x3 acceleration actual value
Effective acceleration actual value in degrees/s
2
.
18.74 x3 acceleration time constant
Time constant of the PT
1
filter to smooth the x3 acceleration actual value (Z18.73–).
18.75 Speed controller output total
Speed controller output (or the entire acceleration set value) from the speed controller in-
cluding the acceleration feedforward term and an additional feedforward (friction compen-
sation, torque coupling etc.) in degrees/s.
18.76 Position actual angle for fieldbus
This parameter displays the angle of the actual position value in a 32 bit resolution and is
updated in the fieldbus cycle.
This parameter corresponds to Z18.55–; however is latched in the controller at the fitting
transfer time of the actual position value. Therefore, it is primarily intended to be an actual
fieldbus value, for the fieldbus especially if an own position error monitoring shall be cal
-
culated on the control.
