Description:
They define the maximum/minimum values for the motor speed reference when the inverter is enabled. They
are valid for any type of reference signal. For details on the actuation of P0133, refer to the parameter P0230
(Dead Zone of the Analog Inputs).
NOTE!
The maximum allowed speed is limited at the value defined by 3.4 x P0402. P0134 is always the
reference limit of the maximum speed, even if the value configured in P0133 is greater than the
value of P0134.
