Setting Table (1) D0 and D1
Torque setting
The peak torque current can be switched using 2-bit data. (Switching is the same for both the A-B and C-D
pairs.)
Setting Table (2) D2, D3, D9, and D10
Decay mode x1 and x0 settings
A value of 37.5% is recommended for a typical condition. Data of (0, 0) specifies a 12.5% decay mode.
