Note:
SPD1, SPD2, SPD3 are the digital inputs of internal speed commands 1, 2, and 3
(corresponding to 0x00A, 0x00B, and 0x00C).
0: OFF (The internal optical coupler corresponding to the input is not conducted.)
1: ON (The internal optical coupler corresponding to the input is conducted.)
The speed limits depend on the absolute values of the parameters and, the directions are the
same as those in torque commands.
