controller activation level (kinetic buffering) (factory setting depends on the Power
Module, 73 % or 76 %)
r1246 V

controller dynamic factor (factory setting: 300 %)
p1255 V
DC min
controller time threshold (factory setting: 0 s)
Maximum duration of the kinetic buffering If kinetic buffering lasts longer than that speci‐
fied in the parameter value, the inverter outputs fault F7406.
A value of 0 deactivates the monitoring.
p1257 V
DC min
controller speed threshold (factory setting: 50 rpm)
When fallen below, the inverter outputs fault F7405.
