Function
Digital Input Control:
Range:0x0000 ~ 0x01FF
Default: 0
Bit0 ~ Bit 7 corresponds with DI1 ~ DI8. The least significant bit
(Bit0) shows DI1 status and the most significant bit (Bit7) shows
DI8 status.
Bit8 ~ Bit14 corresponds with EDI9 ~ EDI14.
Bit0 ~ Bit8 corresponds with DI1 ~ DI9.
Bit settings:
0: Digital input is controlled by external command
.
1: Digital input is controlled by parameter P4-07.
For the settings of DI1 ~ DI8, please refer to P2-10 ~ P2-17.
For the settings of EDI9, please refer to P2-36.
The setting of this parameter determines how the Digital Inputs (DI) accept commands
and signals.
Input commands or signals through the DI can be either from an external source, through
the CN1 interface connector, or via communication (upon software). If this parameter is
set to "0", all commands are external and via CN1; if this parameter is set to
"FFFF"(hexadecimal), all the DI signals are via communication (upon software).
For example, if P3-06 is set to 55 ("binary" display is 01010101), it indicates that Digital
Inputs 1, 3, 5, & 7 are controlled by external commands and Digital Inputs 2, 4, 6, & 8 are
controlled by communication (upon software).
Please see Chapter 4.4.5 DI Signal Display Diagnosis Operation for display layout of the
Digital Signal selection.
The Digital Input Control parameter, P3-06 also works in conjunction with the Digital
Input Status parameter P4-07 which has several functions.
The contents of P4-07 is "read only" via the drive keypad and will display the state on or
off of the eight Digital Inputs which have been set in accordance to P3-06. For Example; if
P3-06 has been set to “FFFF” (All digital inputs are via communication (upon software))
and the P4-07 display is 11 ("binary" display is 00010001), it indicates that the state of
Digital Inputs 1 & 5 are on and the state of Digital Inputs 2, 3, 4, 6, 7 & 8 are off.
