WORD1
• Signed output frequency read from C50
signed scaled +/- 16384 = C11 (max frequency)
• Scaling = C50*16384/C11
• Example 1: WORD1 = 0x2C29, C11 = 50.0Hz
Direction = Sign(0x2C29) = CW
Frequency = ABS(0x2C29) * C11 /16384
= 11305*50/16384 = 34.5 Hz CW
• Example 2: WORD1 = 0xC70A, C11 = 50.0Hz
Direction = Sign(0xC70A) = CCW
Frequency = ABS(0xC70A) * C11 /16384
= 14582*50/16384 = 44.5 Hz CCW
WORD2
Digital inputs status (TB28,E1,E2,E3)
• Bit 0 - TB28 state (1 - asserted)
• Bit 1 - E1 state (1 - asserted)
• Bit 2 - E2 state (1 - asserted)
• Bit 3 - E3 state (1 - asserted)
WORD3
Analog input value 0-1000 -- corresponds to 0-10V
ex. 400 -> 4.00V
