Connection of absolute encoders with SSI-interface .

Birkerød, Denmark and Morrow, OH (USA) -- The firmware of JVL’s QuickStep motors has been extended with yet another function: an SSI encoder interface. It is thus possible to integrate absolute encoder functions in the QuickStep integrated stepper motors and in the stepper motor controller SMC75. Typically, absolute-encoders are used when there is a need to continue operation immediately after power is re-applied to a machine or system — without first having to perform a zero-search reset. Another major reason for using absolute encoders is to correct motor position in relation to the actual physical absolute position measured by the SSI encoder.
