Canon galvano gc-251 ユーザーズマニュアル

CANON Digital Galvano Scanner System

KP-1SM Series + GC-251

Users Manual 1.00

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.
