Data Description
1. SSI and SPI serial signals:
① 、10-bit encoder SSI serial signal:
The minimum value of Tclk in the figure is 1μS (maximum 1MHz). To improve the anti-interference or transmission distance, the Tclk value must be increased (reduce the read clock frequency).
● The 11th to 16th bits of binary data of output signal DO are status and check bits, among which:
OCF indicates that the deviation compensation is completed;
COF means overflow;
LIN means linearity alarm;
MagINC and MagDEC indicate the state of the non-contact sensor (11 is abnormal);
EvenPAR represents the even checksum of bits 1 to 10 (used for transmission error detection);
That is, the 11th to 16th bits are only valid when they have the following configurations:
②, 12-bit encoder SSI serial signal:
The minimum value of Tclk in the figure is 1μS (maximum 1MHz). To improve the anti-interference or transmission distance, the Tclk value must be increased (reduce the read clock frequency).
● The 13th to 18th bits of binary data of output signal DO are status and check bits, among which:
OCF indicates that the deviation compensation is completed;
COF means overflow;
LIN means linearity alarm;
MagINC and MagDEC indicate the state of the non-contact sensor (11 is abnormal);
EvenPAR represents the even checksum of bits 1 to 12 (used for transmission error detection);
That is, the 13th to 18th bits are only valid when they have the following configurations:
③、14-bit encoder three-wire SPI serial signal:
● The minimum value of Tclk in the figure is 125nS (maximum 8MHz). To improve anti-interference or transmission distance, the value of Tclk must be increased (reduce the read clock frequency
Rate).
● MISO is the data sent to the secondary instrument, MSB is in front and LSB is in the back, among which:
The first bit PAR is the parity bit (even check): the even checksum of D13~D0 (3rd~16th bit);
The second bit EF is the transmission error (last time) flag bit: 0 means the last data is normal, 1 means the last data error;
The 3rd to 16th bits are the absolute angle value: D13 to D0 are the absolute angle value at the last time the command code was issued.
