Using Intelligent Input Terminals Section 4-5
4-5-23 Analog Command Hold
This function allows you to make the inverter hold the analog command input
via the external analog input terminal when the AHD terminal is made ON.
While the AHD is turned ON, the up/down function can be used based on the
analog signal held by this function as reference data.
When "
01" is specified for Up/down
memory mode selection (
C101), the
result of up/down processing can be
stored in memory.
If the inverter power is turned on or
the RS terminal turned off with the
AHD terminal left turned on, the data
held immediately before power on or
turning off the RS terminal will be
used.
Note Set frequency remains when the inverter is switched with SET terminal with
AHD on. Turn AHD terminal off to re-hold the set frequency.
Note Frequent use of this function may result in a shorter in memory component of
the inverter.
