Wire exit angle: When mounting a draw-wire displacement sensor, a straight wire exit (±3 tolerance) must be taken into account. If this tolerance is exceeded, increased material wear on the wire and at the wire aperture must be expected. wire aperture 0 (±3 tolerance)

8 5 Output specifications SSI wiresensor Contact description U Encoder power supply connection Encoder ground connection. GND The voltage drawn to GND is U. Positive SSI pulse input. Pulse + forms a current loop with 3 Pulses + pulse -. current of approx. 7 m in direction of pulse + input generates a logical in positive logic. Positive, serial data output of the differential line 4 Data + driver. High level at the output corresponds to logical in positive logic. 5 ZERO Data - 7 Pulses - 8 / 0 DTVLID DTVLID MT 9 UP/DOWN / Not in use 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 00 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. High level at the output corresponds to logical 0 in positive logic. Negative SSI pulse input. Pulse - forms a current loop with pulse +. current of approx. 7 m 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 photoreceiver, 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. oth outputs are Low-active, i.e. are switched through to GND in the case of an error. UP/DOWN counting direction input. When not connected, this input is on High. UP/ DOWN-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.

Polling Mode (asynch, via SDO) Cyclic Mode (asynch-cyclic) The encoder cyclically sends the current process actual value without a request by a master. The cycle time can be parameterized for values between and 5535 ms. Synch Mode (synch-cyclic) The encoder sends the current actual process value after receiving a synch telegram sent by a master. The synch counter in the encoder can be parameterized so that the position value is not sent until after a defined number of synch telegrams. cyclic Mode (synch-acyclic) 0kit/s OFF OFF ON 50kit/s OFF ON OFF 5kit/s OFF ON ON 50kit/s ON OFF OFF 500kit/s ON OFF ON 800kit/s ON ON OFF Mit/s ON ON ON Preset value Rotating direction Scaling With the Preset parameter the encoder can be set to a desired actual process value that corresponds to the defined axis position of the system. The offset value between the encoder zero point and the mechanical zero point of the system is saved in the encoder. With the operating parameter the rotating direction in which the output code is to increase or decrease can be parameterized. Scaling The steps per revolution and the total revolution can be parameterized. The steps per revolution and the total revolution can be parameterized.
