Parameter ID = 67 20
Parameter ID = 68 0
With the default settings at shipping, the setting is (16bit position data length, data least
significant bit 1bit position).
This communication specification has compatibility of XY2-100.
When using the scanner controller of XY2-100 specifications, please use this setting.
Motor rotating angle for the high-speed serial communication data
In the case of 16bit position data
Data: 1 for one pulse that 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 (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.
In the case of 20bit position data
Data: 1 for one pulse that can be specified up to the following positions:
Maximum position: 0xFFFF = 524287 pulses
0-pulse position: 0x8000 = 0
Minimum position: 0x0000 = –524287 pulses
Maximum movable range is set with Parameter ID = 0, 1 (CW limit, CCW limit).
The position data of high-speed serial communication can not exceeded this range.
