Contact less measurement technique gives output in SSI-Synchronous Serial Interface form. Outputs are
taken out through berge pin connection as marked on housing or wires can be directly soldered on gold
plated output PCB terminals.
When CS is at logic low (active), DO will change to High from High Impedance state. After 500ns (CLKFE)
time data is latched into shift register with first falling edge of CLK. With subsequent rising edge of CLK
pulse, one data bit shifts out at DO. Word contains 16 bit. First 10 bits, D9 to D0 are angle information. D9
is MSB and D0 is LSB of angle information.
Subsequent 6 bits are for system information viz.:
1. OCF – Offset Compensation Finished; OC algorithm has finished and data is valid if logic High,
2. COF – Cordic OverFlow; Logic High indicates an out of range error in the cordic part,
data D9 to D0 is invalid. (Send the encoder to manufacturer).
3. LIN – LINearity Alarm; Field generates a critical output linearity when logic High, data D9 to D0
may still be used but may contain invalid data. (Send the encoder to manufacturer).
4. MagInc – Magnitude Increase, field intensity is increasing, check the external magnetic disturbance.
5. MagDec – Magnitude Decrease, field intensity is decreasing, check the external magnetic disturbance.
Both above (4. & 5.) at logic High indicates magnetic field strength is below or above the required limit.
Check for external magnetic influence. If not i.e. field strength is out of range, send the encoder to factory.
Even Parity – bit for transmission error detection of bits 1 to 15 (D9…D0, OCF, COF, LIN, MagInc, DecMag).
Sampling Rate: n = 60/(RPM x 384μs).
Sampling Rate e.g. RPM = 60, then n = 60/(100 x 384 x 10-6) = 1562 samples/second.
MagRngn – Magnet Field Magnitude Range Warning (Optional), it is combination of MagInc and MagDec.
Active Low via open drain output, requires an external pull-up resistor. If the magnetic field is in range,
this output is turned off (logic High).
