High-speed Serial Communication 
Conversion Gain 

High-speed serial communication conversion gain (Unit: Multiple × 1000) 

0: Parameter setting successful 
1: Parameter setting unsuccessful 

High-speed serial communication data is specified by 16 bits. 
Ordinary data is 1 for one pulse and can be specified up to the following positions: 

Maximum position: 0xFFFF = 32767 pulses = About 5.76 deg (GM-1010) 
0-pulse position: 0x8000 = 0 
Minimum position: 0x0000 = –32768 pulses = About –5.76 deg (GM-1010) 

 

If a greater angle is specified, set a magnification by using the high-speed serial 

communication conversion gain (Parameter ID = 13). 
E.g. For x2 (Setting: 2000), the following angle can be specified: 
        –5.76×2 deg to –5.76×2 deg 
    The command resolution will be two times.

Origin Clearance Timing (Head 2) 

Origin clearance timing (0 or 1) 

0: Parameter setting successful 
1: Parameter setting unsuccessful 

This parameter is related to origin detection. 
The value checked by “Command ID = 101: Counter Clear Timing” is set. 
Each motor has a unique value (0 or 1). 

Note: An appropriate value is set at shipping. When only the motor is replaced, the 
value should be checked and set by a command. 
The Origin Clearance Timing (Head 1) parameter should be set at the same time. 

Counter Clear Timing (Command ID = 101) 
      A1C101/ 1 (Axis 1 Head 2) 
Set the value checked above.
