The encoder can be set to zero at any position by means of a HIGH signal on
SSI interface the SET input. Other preset values can be factory-programmed. The SET input
Output driver RS485 transceiver type has a signal processing time of approx. 1 ms, after which the new position data
can be read via SSI or BiSS. Once the SET function has been triggered, the encoder
Permissible load / channel max. +/- 30 mA
requires an internal processing time of typ. 200 ms; during this time the power supply
Signal level HIGH typ. 3.8 V must not be switched off.
LOW with I Load = 20 mA typ. 1.3 V The SET function should be carried out whilst the encoder is at rest.

SSI clock rate 50 kHz ... 2 MHz After Power-ON the device requires a time of approx. 150 ms before valid data
Monoflop time ) 15 µs can be read.
Hot plugging of the encoder should be avoided.
Note: If the clock cycle starts within the monoflop time a second data transfer
begins with the same data. If the clock cycle starts after the monoflop time the
cycle begins with the new values. The update rate is dependent on the clock DIR input
speed, data length and monoflop time.
A HIGH signal switches the direction of rotation from the default cw to ccw.
Data refresh rate resolution ) 14 bit ) 1 µs This inverted function can also be factory-programmed. If DIR is changed when

the device is already switched on, then this will be interpreted as an error. The
status output will switch to LOW.

The status output serves to display various alarm or error messages.
In normal operation the status output is HIGH (open collector with int. pull-up
Incremental outputs (A/B) 22 kOhm).
SinCos RS422 An active status output (LOW) displays:
