P0406 – Motor Ventilation
Adjustable
Range:
0 = Self-Ventilated
1 = Separated Ventilation
2 = Optimal Flux
Factory
Setting:
0
Properties: cfg
Access groups
via HMI:
MOTOR
Description:
During the Oriented Start-up Routine, the value adjusted in P0406 changes the parameters related to the motor
overload automatically, in the following manner:
Table 11.2: Motor overload protection modification in function of P0406
P0406 P0156 (Overl.Curr.100 %) P0157 (Overl.Curr.50 %) P0158 (Overl.Curr.5 %)
0 1.05xP0401 0.9xP0401 0.65xP0401
1 1.05xP0401 1.05xP0401 1.05xP0401
2 1.05xP0401 1.0xP0401 1.0xP0401
ATTENTION!
Refer to the section 11.4 - Optimal Flux for Sensorless Vector Control , for more details on the use
of option P0406=2 (Optimal Flux).
