CNC_DWNSTART3 | PROGRAM

Description

Notifies the start of uploading NC data (NC program, tool offset, etc.) to the internal logic of the Data window library.
(This function must be executed before cnc_download3.)

cnc_download3 function and cnc_dwnend3 function will return EW_FUNC in case that cnc_dwnstart3 function is not executed.

A basic procedure for download is shown below.

Return

EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.

The major error codes are as follows.

Return code	Meaning/Error handling
EW_BUSY (-1)	Busy Series 15i cnc_dwnstart3(cnc_vrfstart) function has been executed. Terminate a downloading (verifying) by using cnc_dwnend3(cnc_vrfend) function. Background edit processing in CNC side Terminate background edit processing in CNC side. Series 16/18/21, 16i/18i/21i, 0i, 30i, Power Mate i, PMi-A cnc_dwnstart3(cnc_vrfstart) function has been executed. Terminate a downloading (verifying) by using cnc_dwnend3(cnc_vrfend) function.
EW_ATTRIB (4)	Data attribute error Data type (type) is illegal.
EW_NOOPT (6)	No option Series 15i In case of custom macro variables or pitch error compensation data, this function needs the option for the target data. Series 16/18/21, 16i/18i/21i, 0i, 30i, Power Mate i, PMi-A In case of custom macro variables, work zero offset or pitch error compensation data, this function needs the option for the target data.
EW_PARAM (9)	CNC parameter error Series 15i Parameter (No.20,22:Input device) is wrong. Series 16/18/21, 16i/18i/21i, 0i, 30i, Power Mate i, PMi-A In case of parameter, set 'parameter write enable' state by setting screen.
EW_MODE (12)	CNC mode error Series 15i (in case of except NC program) In case of tool offset data and custom macro variables, change CNC mode to MDI or emergency state. In case of parameter, pitch error compensation data and work zero offset data, change CNC mode to emergency state. Series16/18/21, 16i/18i/21i, 0i-A/B/C, Power Mate i (in case of NC program) MDI mode Change CNC mode to any mode except MDI. Background edit processing in CNC side Terminate background edit processing in CNC side.
EW_REJECT (13)	CNC execution denied (Series 16/18/21, 16i/18i/21i, 0i, 30i, Power Mate i, PMi-A) CNC is machining Cannot download while automatic operation is being executed on CNC in case of except NC program.
EW_ALARM (15)	Alarm state (Series 16/18/21, 16i/18i/21i, 0i, 30i, Power Mate i, PMi-A) Alarm (PS000, PS101) on CNC side Reset the alarm on CNC.
EW_PASSWD (17)	Specified CNC data cannot be written because the data is protected. (Series 16/18/21, 16i/18i/21i, 0i-A/B/C)

CNC option

And this function is related to the following CNC option.

• Series 15i

Pitch error compensation
Custom macro

• Series 16i/18i/21i, 0i

Pitch error compensation
Custom macro
Work zero offset

For HSSB connection,

The extended driver/library function is necessary.

For Ethernet connection,

The Ethernet function and the extended driver/library function are necessary.

However, in case of Series 16i/18i/21i-B, 0i-B/C/D/F, Series 30i and PMi-A, the required CNC option is as follows.

When Embedded Ethernet is used,

above two optional functions are not required.

When Ethernet board is used,

only Ethernet function is required.
