P1011 –  E.P. Speed Reference  

Adjustable 

Range:

0 to 18000 rpm

Factory 

Setting:

-

Properties:

Description:

Read only parameter that presents, in rpm, the current speed reference value of the electronic 

potentiometer application. 

P1012 – E.P. Speed Reference Backup 

Adjustable 

Range:

0 = Inactive

1 = Active

Factory 

Setting:

Properties:

-

Access Groups 

via HMI:

SPLC

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 “A750: Set a DI for Multispeed” and the speed 

reference of the inverter will not be enabled.
