2. Digital - SSi Interface (absolute position)
DL-25
Sold & Serviced By:
Synchronous Serial Interface (SSi) allows for serial transmission of
absolute position data from the Electric Encoder™ responding to
controller clock pulses. The Encoder and controller are linked by
clock and data differential signal lines.
n = total number of data bits.
T = clock period (sec) - user defined.
1/T = clock frequency 0.5 ÷ 2.5 MHz (user defined).
t1 = minimum time required for the encoder to freeze data
and preset the shift registers before receiving the first
rising edge to prompt the MSB
t2 = data transmission delay (increases with cable length)
t3 = required delay to refresh position data between
subsequent position reads.
