Description:
This parameter sets whether the backup function of the electronic potentiometer speed
reference is active or inactive.
If P1012 = 0 (Inactive), the inverter will not save the value of the speed reference when
disabled. Therefore, when the inverter is enabled again, the speed reference value will be the
minimum speed set in P0133.

4.2.3 Multispeed Application

The CFW700 has the Multispeed application that allows the speed reference to be set by
the values defined at parameters P1011 to P1018 through the logical combination of digital
inputs DI4, DI5 and DI6, having the limit of eight pre-programmed speed references. It brings
advantages such as stability of the pre-programmed fixed references and electrical noise
immunity (isolated digital inputs DIx).
The speed reference selection is done by the logical combination of the digital inputs DI4, DI5
and DI6. Their respective parameters (P0266, P0267 and P0268) must be set to "Function 1
of the Application (Multispeed)". If any digital input us set to "Function 1 of the Application",
the following alarm message will be displayed "A0750: Set a DI for Multispeed" and the speed
reference of the inverter will not be enabled.
