Origin Clear Timing (Head 1)
Data Origin clear timing (0 or 1)
Return Value 0: Parameter setting successful
1: Parameter setting unsuccessful
Explanation 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.
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 Clear Timing (Head 2) parameter should be set at the same time.

High Speed Serial Data to angle gain
Data High-speed serial communication conversion gain (Unit: Multiple × 1000)
Return Value 0: Parameter setting successful
1: Parameter setting unsuccessful
Explanation 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 this parameter.
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.
