INPUT COMMAND/INTERFACE CODING:

 
PIN 1 Positive Common (V = 4.5 to 5.5 VDC at 30 mA max.)
   
PIN 2 Polarity Bit (Low = CW, High = CCW rotation)
   
PIN 3 Speed Control MSB
   
PIN 4 Speed Control (Bit 5)
   
PIN 5 Speed Control (Bit 4)
   
PIN 6 Speed Control (Bit 3)
   
PIN 7 Speed Control (Bit 2)
   
PIN 8 Speed Control (Bit 1)
   
PIN 9 Speed Control (Bit Ø)
   
PIN 10 Input ground
   
FULL SPEED = All bits low (CW or CCW as desired)
 
ZERO SPEED = Bits 8 through Ø high
