Explanation:
The equivalent 7-bit binary number is used to program forward/reverse motion for each
of the 7 speed steps.
Example: parameter value = d50 equals 0110010

Setting Example:
The direction of muti-speed1=Fwd.
The direction of muti-speed2=Rev.
The direction of muti-speed3=Fwd.
The direction of muti-speed4=Fwd.
The direction of muti-speed5=Rev.
The direction of muti-speed6=Rev.
The direction of muti-speed7=Fwd.
0 = Fwd.
1 = Rev.

Direction
Decimal value = binary bit 7x2 + bit 6x2 + bit 5x2 + bit 4x2 + bit 3x2 + bit 2x2 + bit 1x2
= 0x2 + 1x2 + 1x2 + 0x2 + 0x2 + 1x2 + 0x2
= 0 + 32 + 16 + 0 + 0 + 2 + 0
= 50
