p1245 V
DC min
controller activation level (kinetic buffering) (factory setting depends on the Power
Module, 73 % or 76 %)
r1246 V
DC min
controller activation level[V]
r1246 = p1245 × √2 × p0210
p1247 V
DC min
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.
Advanced commissioning
6.34 Kinetic buffering (Vdc min control)
