Analog Frequency Reference Sample/Hold (Setting: 1E); External Faults (Settings: 20 To 2F); External Fault Settings - YASKAWA VARISPEED-616G5 Instruction Manual

The trim control increase function adds the level in d4-02 to the analog frequency reference.
D
The trim control decrease function subtracts the level in d4-02 to the analog frequency reference.
D
These functions are effective when the frequency reference is input from an analog input. These func-
D
tions must both be set at the same time or an OPE03 fault will occur. The analog frequency reference
won't be changed when both the trim control increase and decrease inputs are ON. The output frequen-
cy will be zero when the trim control decrease input is ON and the result of the subtraction is less than
zero.

Analog Frequency Reference Sample/Hold (Setting: 1E)

The analog input value will become the frequency reference 100 ms after the multi-function input
D
closes.

Analog Frequency Reference Sample/Hold
The analog frequency reference sample/hold function is valid only for terminals 13, 14, and 16 or for
D
the analog inputs from the AI-14U or AI-14B.
An OPE03 fault will occur if two or more of the following signals turn ON at the same time: accelera-
D
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)

With this setting, the multi-function input can be used to stop the Inverter or output an alarm when a
D
malfunction or fault occurs in a peripheral device.
There are 16 external fault inputs available with all 16 combinations of the following variables. Select
D
