Maximum speed:
The former maximum speed N
max
= 3000 rpm obtained with U
n
=400 V
rms
and a speed N
n
=3000 rpm leads to the new maximum speed N
max2
given as follows:

N.B.
If the rated voltage increases (U
n2
> U
n
), the new rated speed N
n2
and the new maximum
speed N
max2
will be greater than the former ones N
n
and N
max
. Moreover you will have to
check that the drive still shows able to deal with the new maximum electric frequency.
Warning: If the main supply decreases, you must reduce the maximum
speed accordingly in order to do not damage the motor.
In case of doubt, consult us.
