Functions
Analog Command Held Function (AHD)
While the AHD terminal is turned on, the Inverter keeps external analog input results on hold.
While the AHD terminal is turned ON, the UP/DWN function can be used based on the
reference value of the analog signal kept on hold by this function. If UP/DWN Storage Selection
(C101) is set to "01", the Inverter can store an UP/DWN result.
If the power is turned on with the AHD terminal turned on, or if the Reset (18: RS) terminal is
turned on and then off, the Inverter employs the data kept on hold immediately before.
 If the control function is switched via the SET terminal with the AHD terminal turned ON, the set
frequency is retained. To switch the control function, turn OFF the AHD terminal once, and keep
the analog signal on hold again.
 If this function is frequently used, the internal EEROM element service life may be shortened.
