Backup Of The Speed Reference; Parameters For Reference Frequency - WEG CFW100 Programming Manual

P133 – Minimum Frequency Reference
Adjustable 0.0 to 300.0 Hz
Range:
Properties:
P134 – Maximum Frequency Reference
Adjustable 0.0 to 300.0 Hz
Range:
Properties:
Description:
Limits for frequency reference of the inverter. Those limits are applied to any reference source, even in case of
"13-bit speed".

7.2.2 Backup of the Speed Reference

P120 – Backup of the Speed Reference
Adjustable 0 = Inactive
Range:
1 = Active
2 = Backup by P121
Properties:
Description:
This parameter defines the operation of the Backup function of the Speed Reference from one of the options
active (P120 = 1), inactive (P120 = 0) and by P121 (P120 = 2). This function, in turn, determines the form of backup
of the digital references of the sources: HMI (P121), E.P., Serial/USB (P683), according to
P120
If P120 = Inactive, the inverter will not save the speed reference value when it is disabled. Thus, when the inverter
is enabled again, the speed reference value will become the frequency minimum limit value (P133).
If P120 = Active, the value set in the reference is not lost when the inverter is disabled or powered down.
If P120 = Backup by P121, the reference initial value is fixed by P121 at the enabling or power-up of the inverter.
