Only
(European
Model)
If
inputting the master speed frequency reference only, input the voltage reference to control circuit terminal
A1.
The voltage range canbe selected by setting H3-01.

2-Step
Switching:
Master/Auxiliary
(European
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. The voltage range can be selected by setting H3-01.

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).
