4.2.57 Output phase failure protection selection (Pr. 251)
Pr. 251 "output phase failure protection selection"
You can make the output phase failure protection (E.LF) function which stops the inverter output invalid if one
of the three phases (U, V, W) on the inverter's output side (load side) becomes open.
4.2.58 Override bias/gain (Pr. 252, Pr. 253)
Pr. 252 "override bias"
Pr. 253 "override gain"
You can extend the 50% to 150% override range (to 0% to 200%), which is covered when Pr. 73 "0 to 5V, 0
to 10V selection" is used to select the override, and set the override value as desired.
