b1-01
Input the Speed Reference from the Digital Inputs (b1-01=0)
When b1-01 is set to 0 the speed reference can be selected from preset speeds using the digital inputs of the
inverter. Refer to
Input the Speed Reference Using a Voltage Signal (b1-01=1)
When b1-01 is set to 1 the speed reference can be input at terminal A1 as a 0 to +10V signal. If an analog
option card AI-14B is installed, the A1 signal is replaced by the Channel 1 input of the AI card.
The analog reference signal can also be used as 1st speed if multispeed operation is selected (d1-18=0, refer to
page 6-5, Speed Selection Sequence Using Digital Inputs
If parameter d1-18 is set to 0 and b1-01 is set to 1, the analog input value replaces any speed selected by the
digital inputs except the service speed.

Input the Speed Reference Using an Input Option Card (b1-01=3)
When b1-01 is set to 2 the speed reference can be input using an input option card, for example a field bus
communications card.
