Model

1 Series code: HAE stands for Hall-type absolute rotary encoder;
2 Shell outer diameter: 38 means shell outer diameter Φ38mm;
3 Output interface: U*1 is the voltage signal interface circuit, C is the NPN open collector interface circuit, R is the RS485/RS422 output interface circuit;
4 Power supply voltage: 05V means DC5V voltage, 24V means DC24V voltage;
5 Absolute value digits: 10 means 10 bits (1024), 12 means 12 bits (4096), 14 means 14 bits (16384);
6 Special options: A means no standard model, B*2 means adding PWM*2 output signal;
7 Cable length: 1 means special length 1m, standard length 0.3m omitted.
*1: The voltage signal interface can be selected only when the power supply voltage is DC5V.
*2: When the power supply is DC5V, PWM is a voltage pulse width modulation output signal, and when the power supply is DC24V, PWM is an NPN open collector pulse width modulation output signal.

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.
