Blocking Inverter Outputs (Baseblock Commands)
Set 8 or 9 (Baseblock command NO/NC) in one of the constants H1-01 to H1-05 (multi-function contact input
terminal S3 to S7 function selection) to perform baseblock commands using the terminal's ON/OFF operation,
and thereby to block the inverter output.
Clear the baseblock command to restart the operation using the speed search method set in b3-01 (speed
search selection).
