SSI

Encoder power supply connection.
Encoder ground connection. The voltage drawn to GND is UB.
Positive SSI pulse input. Pulses + forms a current loop with pulse -. A current of approximate-
ly. 7 mA indirection of pulse + input generates a logical 1 in positive logic.
Positive, serial data output of the differential line driver. A High level at the output corresponds
to logical 1 in positive logic.
Zero setting input for setting a zero point at any desired point within the entire resolution. The
zeroing process is triggered by a High pulse (pulse duration ≥ 100 ms) and must take place
after the rotating direction selection (UP/DOWN). For maximum interference immunity, the
input must be connected to GND after zeroing.
Negative, serial data output of the differential line driver. A High level at the output corre-
sponds to logical 0 in positive logic.
Negative SSI pulse input. Pulse - forms a current loop with pulse +. A current of approx. 7 mA
in direction of pulse - input generates a logical 0 in positive logic.
Diagnosis outputs DV and DV MT Jumps in data word, e.g. due to defective LED or photore-
ceiver, are displayed via the DV output. In addition, the power supply of the multiturn sensor
unit is monitored and the DV MT output is set when a specified voltage level is dropped below.
Both outputs are Low-active, i.e. are switched through to GND in the case of an error.
High means increasing output data with a clockwise shaft rotating direction when looking at
the flange. UP/ DOWN-Low means increasing values with a counter-clockwise shaft rotating
direction when looking at the flange.
