6-4-12 Analog Command Hold Function (AHD)

The input terminal 019 [AHD] analog command holding holds the command of the analog input when
the input terminal becomes ON. When the input terminal becomes OFF, the command returns to the
analog command.
If the main speed command [AA101] is an analog input command (01-03), this function is effective even
when data are held by the analog command holding [AHD] function.
If 019[AHD] function is effective, the held data can be moved up/down by using [FUP]/[FDN] function.
Precautions for Correct Use
Data changes with the [FUP]/[FDN] function are not saved.
