7.21 Analog Frequency Reference Sample/Hold
D The analog frequency reference sample/hold function is valid only for terminals 13, 14, and 16 or for
the analog inputs from the AI-14U or AI-14B.
D An OPE03 fault will occur if two or more of the following signals turn ON at the same time: accelera-
tion/deceleration ramp hold command (0A), up/down commands (10 or 11), trim control increase/de-
crease commands (1C or 1D), and the analog frequency reference sample/hold command.
External Faults (Settings: 20 to 2F)
D With this setting, the multi-function input can be used to stop the Inverter or output an alarm when a
malfunction or fault occurs in a peripheral device.
D There are 16 external fault inputs available with all 16 combinations of the following variables. Select
the setting with the desired combination.
x Input level: Normally open or normally closed
x Detection method: Always or During operation only
x Operation selection: Deceleration to stop, Coast to stop, Emergency stop, or Continue opera
