8.28 DIx_Select = 28, CLOCK input of Timer/Counter
Refer to Sec.8.7, the Functional Block Diagram of the Internal Timer/Counter Module.
Note: Not every DIx input can select this function; only DI2(28) and DI4(28) are useful.
DI1(28): Used for AUTO-RUN mode, refer to Sec. 12
(for PDA/PDE/PDH series only)
DI2(28): Used for general purpose Timer/Counter, refer to Sec. 8.7, 8.11, 8.36.
DI3(28): No function
DI4(28): Used for AUTO-RUN mode, refer to Sec. 12
(for PDAN series only)
If this function is used, the Counter Module will advance one count when the input status of DIx changes from OFF to
ON.
The maximum input clock rate is limited to 1,000 Transitions/Second.
8.29 DIx_Select = 29, reserve
8.30 DIx_Select = 30, /OH function
When any digital input terminal select this function, it must remain in
ON state for normal operation
.
Else if the input is
OFF
, the inverter will disable the output transistors, and show
OH
alarm message on the display.
Refer to mode-6, for complementary function.
8.31 DIx_Select = 31, Normal/Auto Switch
Refer to Sec.12, the description of AUTO RUN Function.
Parameter Pr.72 determines the Auto Run Mode of the inverter.
This Digital Input function provides an easy way to change between Normal or Auto Run mode.
When the selected DIx input is OFF, then Pr.72 determines the inverter running mode.
If the input is ON, then it will force the inverter to run under Normal mode (equal to Pr.72=0).
Note: a. If Pr.72=0, selects Normal Run Mode.
b. The status change of the DIx will be effective only when the inverter is stop.
8.32 DIx_Select = 32~35, reserve
