Name

High-speed Serial Communication

Conversion 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 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.

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 (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.
