Yaskawa VS-626 MC5 - Manual (Page 107)

Basic Operation
6.1.2 Frequency Reference Settings: b1-01, H3-01, H3-08, H3-09
- 4
6.1.2 Frequency Reference Settings: b1-01, H3-01, H3-08, H3-09
These settings are required when inputting analog voltage or current signals from the control circuit termi-
nals.
J Frequency Reference Selection: b1-01
D Constant b1-01 is used to select the reference source.
