2.1.2 Speed Reference via Digital Inputs

The control connections (analog inputs/outputs and digital inputs/outputs) wired at the CFW-11 electronic
control board CC11 terminal strip XC1, when the speed reference is through the logical combination of digital
inputs for 5 references, are presented next.

NOTE!
It is necessary to install the IOC-01 or IOC-02 accessory module in case the DI9, DI10, DI11 and
DI12 digital inputs and/or the DO6 and DO7 digital outputs use is required. Refer to the CFW-11
frequency inverter manual for more information on accessory modules.
