Set Bus Function

This chapter mainly introduces bus function in bus type configuration.

Setting bus function includes the following:

Before commissioning, please check the hardware configuration, and make sure all have been correctly connected.

Set Drive Axis address

Setting drive axis address is the key to data transmission among control system, Lambda controller and the driver.

Set Axis Address of YASKAWA Drive

Setting axis address of YASKAWA drive via rotary switch S2 and toggle switch S3.

For a YASKAWA drive, to set axis address, do the following:

  1. Set S3: set switch 3 according to actual situation, and the other use the factory setting.

    Please refer to the table below for setting:

    Switch No. Function Description Factory
    1 Setting communication speed OFF: 4Mbps(M1)
    ON: 10Mbps(M2)    		 ON
    2 Setting byte number OFF: 17 bytes
    ON: 32 bytes    		 ON
    3 Setting station address OFF: Actual address=40H+S2
    ON: Actual address=50H+S2    		 OFF
    4 System reservation (Unchangeable) OFF OFF

  2. Set S2: Rotate S2 to the target value.

    Please refer to the table below for actual satation address:

    No.3 of S3 S2 Station address No.3 of S3 S2 Station address
    OFF 0 Invalid ON 0 50H
    OFF 1 41H ON 1 51H
    OFF 2 42H ON 2 52H
    OFF 3 43H ON 3 53H
    OFF 4 44H ON 4 54H
    OFF 5 45H ON 5 55H
    OFF 6 46H ON 6 56H
    OFF 7 47H ON 7 57H
    OFF 8 48H ON 8 58H
    OFF 9 49H ON 9 59H
    OFF A 4AH ON A 5AH
    OFF B 4BH ON B 5BH
    OFF C 4CH ON C 5CH
    OFF D 4DH ON D 5DH
    OFF E 4EH ON E 5EH
    OFF F 4FH ON F 5FH

  3. Restart the drive.

Set Axis Address of WISE Drive

Setting axis address of WISE drive via the front panel.

For a WISE driver, to set axis address, do the following:

  1. Set parameter Pr001 Control mode setup as 1 Position control mode as following:

  2. Set axis address No. as following:

  3. Restart the drive.

Set Control System Parameters

To use bus function, setting control system parameters in NcStudio software is required.

To set the following parameters, please refer to Setting Parameters:

N11001 Encoder type
: Choose encoder type according to actual situation.
: 0: Normal
: 1: Incremental
: 2: Absolute

N15000 Control system type
: Choose control system type.
: 0: Non-bus control system
: 1: Bus control system

N16050~16053 Servo type X/Y/A
: Choose servo type.
: 0: YASKAWA ∑5 servo driver
: 1: YASKAWA ∑7 servo driver
: 2: WISE servo driver

N16000~16003 Driver station address X/Y/A
: It should be the same with rotary switch setting of driver station address. 0 is invalid address.
: Setting range: 0~15

N16010~16013 Driver station address setting switch X/Y/A
: It should be the same with toggle switch S3 setting of driver station address.
: Yes: PN
: No: OFF

N16020~16023 Encoder digit X/Y/A
: The digit number of encoder of the servo motor.
: Setting range: 10~30

N16990 Second axis driver station address
: The driver station address of the second axis.
: Setting range: 0~15

N16991 Second axis driver station address setting switch
: The driver station address setting switch of the second axis.
: Yes: ON
: No: OFF

Set Drive Parameters

To use bus function, setting drive parameters in NcStudio software is required.

To set drive parameters, do the following:

  1. Click Machine Tool → Set Servo Param in menu bar. A dialog box named Driver Parameter pops up.

    For a WISE drive, all parameters will be shown in the dialog box. While for a YASKAWA drive, only part of parameters will be shown. If you need to add more, click Add.

  2. Click Select axis to select an axis to be set.

    Different axis has different drive and parameters.

  3. Scroll the mouse or press arrow keys "↑" and "↓" on keyboard to select parameter.

  4. Press "Enter" or double click to modify the selected parameter.

  5. Click OK.

  6. Click Machine Tool → Clear Servo Alarm.
