If p0680 change is rejected, a check should be performed as to whether the input terminal is already being used in p0488, p0489, p0493, p0494, p0495, p0580, p2517 or p2518.
p0680无法设置可能是 p0488, p0489已设置。试试：
CU数据 P0680[0] Central probe input terminal = 0
P0680[1] Central probe input terminal = 0
p0680[2] Central probe input terminal = 0

驱动数据 p0488[0] 测头1输入端口: 编码器 1 = 2 → X 122.10
p0488[1] 测头1输入端口: 编码器2 = 2 → X 122.10
p0489[0] 测头2输入端口: 编码器1 = 3→ X 122.11
p0489[1] 测头2输入端口: 编码器2 = 3 → X 122.11
