P2376[0...2] Motor staging delay over-
ride [%]
0.0 - 200.0 25.0 U, T PERCEN
T
DDS Float 3
P2376 as a percentage of PID setpoint. When the PID error r2273 exceeds this value, a motor is
staged/destaged irrespective of the delay timers.
Note: The value of this parameter must always be larger than staging hysteresis P2373.
P2377[0...2] Motor staging lockout
timer [s]
0 - 650 30 U, T - DDS U16 3
Time for which delay override is prevented after a motor has been staged or destaged.
This prevents a second staging event immediately after a first, being caused by the transient conditions
after the first staging event.
P2378[0...2] CO: Motor staging fre-
quency f_st [%]
0.0 - 120.0 50.0 U, T PERCEN
T
DDS Float 3
The frequency as a percentage of maximum frequency. During a (de) staging event, as the converter
ramps from maximum to minimum frequency (or vice versa) this is the frequency at which the digital out-
put is switched.
This is illustrated by the following diagrams.
