3, Configuration of the data for homing 

Here are simple descriptions of the data for executing homing.

     

 

CD has 27 

methods for homing, referring the CANopen’s definition of DSP402. 

1st-14th methods use Z signal as homing signal.   

17th-30th methods use external signal as homing signal. 

 

 

 

Method 1: Homing on the negative limit switch and index pulse

 

Using this method, the initial direction of movement is leftward if the negative limit 

switch is inactive (here shown as low). The home position is at the first index pulse to the 

right of the position where the negative limit switch becomes inactive. 

   

 

Method 2: Homing on the positive limit switch and index pulse 

Using this method, the initial direction of movement is rightward if the positive limit 

switch is inactive (here shown as low). The position of home is at the first index pulse to 

the left of the position where the positive limit switch becomes inactive. 

0x607C0020    Home_Offset 

Home offset 

In Homing mode, set the offset relative to 

the zero point. 

0x60980008    Homing_Method 

Homing method 

Select the homing method 

0x60990120    Homing_Speed_Switch  Speed  for  searching 

the limit switch 

Set  the  speed  for  searching  the  limit 

switch which defined as homing signal. 

0x60990220    Homing_Speed_Zero 

Speed  for  searching 

the Zero point. 

Only valid when find Index signal. 

0x60990308    Homing_Power_On 

Homing  when  power 

on 

Every  time  after  power  on,it  will  start 

homing once. 

0x609A0020  Homing_Accelaration 

Homing acceleration 

Control the acceleration of homing
