Parameter of controller can be changed by the following sending method to controller.
Also in response to parameter send, the controller always returns a reply with data.
The data contents depend on the command. (For details, see 7-2, “Command Details.”)
When changed a parameter of it, to start it by the same setting in power supply on at the next
time; the parameter that changed, it is necessary to write in it at ROM.

For the ROM Write of the parameter, a reply with data has been sent by all means by a controller.
The content of data is different by a parameter. (For details, see 7-3, “Parameter Details.”)
(Note) Please make the ROM write of the parameter after enough confirmation. Depending on
value for change, the controller may not start normally.
For the support of other communication specifications, contact the Sales Department.

Note: For setting high-speed serial communication mode or controller activation in high-speed serial
communication mode at power-on, high-speed serial communication signals are necessary. Enter the
CLK, FS, and DAT signals in advance.
For how to set the activation mode, see 6-1, “Setting Activation Mode.”

(Target Position Data) XDAT、YDAT
The data length of the target position data by the high-speed serial communication can be
changed by two following parameters.
The target position data length can be changed in 16bit – 20bit.
Parameter ID DATA
16: 16bit Data※
17: 17bit Data
67
18: 18bit Data
19: 19bit Data
20: 20bit Data
The least significant bit position of the target position data of high-speed serial communication
20bit data can be set by following parameter.
The right shifts this number of bit make the target position data.
Parameter ID DATA
0: 0bit position
1: 1bit position※
68
2: 2bit position
3: 3bit position
4: 4bit position
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)
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.

(Status) STS
The status of controller is sent by status line (STS) of high-speed serial communication.
The contents of status sending from a controller can be changed by the following parameter.
