TECHNICAL DATASHEET Stainless Steel Encoders AC 61 - SSI-P TECHNICAL DATA electrical (continued) RECOMMENDED DATA TRANSFER RATE bei SSI SYNCHRONOUS-SERAL TRANSFER (SSI) A clock brush is applied at the SSI inter- face, causing the encoder data to be seri- ally clocked out. With each new clock brush (min. interval 30 ms) new data is rea- dout. The following main parameters are programmable: Preset: Software-Preset and via input/ pushbutton settable presets (can be inactivated) Offset: Relative shifting of actual enco- der value. Scaling: The actual value of the encoder is multiplied with the factor entry, increments per measuring distance or per revolution). Direction of rotation:

Can be changed via software or input (can be inacti- vated) Output formats SSI: Tree format or stan- dard format (MSB oriented) Output code: The choices are Gray or binary code, integer or two's comple- ment representation. Selection of signi- ficant bit between 16 and 24 Bit. In addition, programming of max. 7 status bits is possible: up to 4 warning positions overspeed encoder standstill parity encoder error direction of rotation PROGRAMMING with SSI Information shown in these data sheets are for guidance purposes only, no liability is accepted for any errors or omissions.

Drives Clock and Data / RS422 Parametrization Resolution, Code type, Direction, Output format, Warning, Alarm Control inputs Direction, Preset 1, Preset 2 Alarm output Alarm bit Status LED Green = ok, red = alarm The max. data transfer rate depends on the cable length. For Clock / Clock and Data / Data please use twisted pairs. Use shielded cable. Cable length Frequency To program the absolute encoder you require a PC, the software WinSSI and the adapter cable. The encoder is connected to the power supply and the serial interface of your PC with the adapter cable.

Using the menue- assisted programme you can then confi- gure the encoder according to the parameters you require. Doc No: AE0020 Rev: 001 Impulse Automation Limited United Kingdom Company Registration 665193 Page 2008-04-24 16:01:00 2
