    1 1 .1. Power Supply The unit accepts DC supply from 17 V to 30 V when using terminals 1 and 2. The consumption depends on the level of the supply voltage (typical 130mA at 30V or 190mA at 17V, plus current taken from aux. output). For AC supply the terminals 0 VAC, 115 VAC or 230 VAC can be used.

    5 5 . Hints for Application 5.1. Master and Slave Operation Set register “Mode” to position “Master” when the unit should generate the clock signal for the encoder. In this case the clock terminals (CLK) are configured as clock outputs. When your encoder receives already its clock from another device and the unit should only “listen”...

    With Master operation, therefore other settings will result in generation of the next upper or lower value according to above list. With all settings <250.0 kHz the error between set rate and generated rate becomes negligible. It is mandatory to set the Baud rate also with Slave operation. In this case, however, the setting serves only to determine the pause time for correct synchronization (pause is detected after 4 clock cycles).

  • Page 28: Scaling Of The Display

    5 5 .3. Scaling of the Display Under consideration of the scaling parameters which have been described previously, the final display value of the unit results from Encoder SSI data are always positive only. Where also negative values should be indicated, this can be achieved by corresponding setting of the parameters „0-Position“...

  • Page 29: Basic Modes Of Operation

    5 5 .4. Basic Modes of Operation 5.4.1. Normal SSI display Normal operation provides calculation of the display value from the SSI encoder data and the settings of the scaling factors. Negative values can be achieved by corresponding setting of the zero-position, or by inversion of the direction bit.

  • Page 31 5 5 .4.2. Round-Loop Function This mode of operation is used frequently with rotating round tables or similar applications, where the absolute encoder information is only used for a limited and repeating range of the encoder (like one revolution of the table, which must not at the same time mean one revolution of the encoder shaft).
  • Page 32 5 5 .4.3. Operation with Zero-Crossing As a special advantage, the round-loop mode can be used to bypass the mechanical encoder overflow position, because in this mode the unit continues with steady operation, even while the SSI encoder signal passes the mechanical overflow position from maximum to zero. This feature can help to avoid mechanical adjusting of the encoder zero position with many applications, when no other means for the mechanical zero definition is available.

    6 6 . Special Functions 6.1. Linearization This function allows converting a non-linear input signal into a linear presentation or vice- versa. There are 16 interpolation points available, which can be freely arranged over the whole measuring range in any distance. Between two points the unit automatically will interpolate straight lines.

    6 6 .2. Manual Input or „Teaching“ of the Interpolation Points Interpolation points to form the linearization curve can be entered one after another, using the same procedure as for all other numeric parameters. This means you will enter all parameters P01_x to P16_x and P01_y to P16_y manually by keypad.
  • Page 37 Once we have reached and stored the last interpolation points P16_x/y, the routine will restart with P01_x again. You are free to double-check your settings once more or to make corrections. To conclude the Teach procedure, keep ENTER down for about 2 seconds. In the display you will read “StOP”...
