5.2 Speed displays
Set value displays:
Setpoint speed display before ramp generator in
state OPERATION ENABLED at mode of oper-
ation = 2 „velocity mode“
Set speed for speed controller after ramp gener-
ator and the PT1 filter of the set speed (cs19 ref
speed PT1-time)
Set speed at the ramp generator output
Setpoint speed display before ramp generator
(operating mode independent)
filtered actual speed
(ru08 to PT1 filter / filter time constant = is39)
ru86 displays the setpoint that would be active if
the blockade function did not determine the set-
point speed
smoothed ramp output value (smoothing ac-
cording to cs19; see point B in Figure 60)
Actual speed / frequency displays:
Actual speed:
- measured speed at control mode
with encoder
- estimated speed at ASCL / SCL
- ramp output speed at v/f control
Actual speed measured with encoder
Current actual speed as ru08 normalized by the
velocity shift factor co02
filtered actual speed (ru08 after PT1 filter with
the time constant is39 / 0 = filter switched off)
Difference speed displays:
Difference between setpoint speed and actual speed
