Table 6.6
- Frequency reference
The multispeed function has some advantages for the
stability of the fixed preprogrammed references and the
immunityagainst electrical noises(digital referencesand
insulated digital inputs).

Define
s the maximum and minimum output frequency

when inverter is enabled.
It is valid for any type of speed reference excepting JOG.
The parameter P133 defines a dead zone when analog
inputs are used - refer to the parameter P233 to P240.
