MOTOROLA MVME133SA-20A Logic control card

The incremental encoder interface is included as part of the delivery package for servodrives which do not have a CONNECT module (standard version). Set the parameter ROD/SSI to ROD with the operator software BS7200. The position of the motor shaft is calculated in the servo-amplifier from the cyclically-absolute 14-bit information of the resolver digital converter. Pulses are derived from this information which are compatible to the incremental encoder. Two pulse trains (signals A and B) which are electrically set off by 90° and a zero pulse are available at the SubD connector. You can choose between 500, 512, 1000 and 1024 pulses per turn (parameter: RESOLUTION).

SSI-Interface, (only for units without a CONNECT module)

The SSI position interface is included as part of the delivery package for servodrives which do not have a CONNECT module (standard version) . Set the ROD/SSI parameter to SSI with the operator software BS7200. The signal sequence can be output in Gray code (standard) or in Binary code. Set the SSI-CODE parameter by using the operator software or the operating keys. Operate the interface off an external supply voltage (GND : X5.1 and +5V : X5.8). PGND must be connected to the control. A serial signal is read out synchronously by the interface at a clock rate of max. 1.5 MHz. You can adapt the servo-amplifier to the clock frequency of the SSI evaluation by using the SSICLOCK parameter (200 kHz or 1.5MHz and reversed).
