nInputting the Frequency Reference Using Voltage (Analog Setting)
When b1-01 is set to 1, you can input the frequency reference from control circuit terminal A1 (voltage input),
or control circuit terminal A2 (voltage or current input).
Inputting Master Speed Frequency Reference Only (Asian Model)
If inputting the master speed frequency reference only, input the voltage reference to control circuit terminal
A1.
Fig 6.4 Master Speed Frequency Reference Input
2-Step Switching: Master/Auxiliary (Asian Model)
If performing 2-step switching between master and auxiliary speed frequencies, input the master speed fre-
quency reference to control circuit terminal A1, and input the auxiliary speed frequency reference to A2.
When terminal S3 (multi-step speed command 1) is OFF, terminal A1 (master speed frequency reference) will
be the Inverter frequency reference, and when terminal S3 is ON, terminal A2 (auxiliary speed frequency ref-
erence) will be the Inverter frequency reference.

Setting Precautions
When inputting a voltage signal to terminal A2, observe the following precautions.
• Turn OFF pin 2 on DIP switch S1 for switching between voltage and current (factory setting is ON).
