ELECTRICAL CONNECTION / SSI INTERFACE

5.2

SSI interface

5.2.1

Data transfer

Clock

Data

Clock frequency 100 kHz��2 MHz

Monoflop time (t) 20 µs (internal)

n, m Number of bits

For continous clocking, the SSI word is transmitted only once followed by zero

values (no ring register operation)�

5.2.2

Function „RESET"

With the function „RESET" (RESET input) the position value of the SSI signal is set to

0 (factory setting, other values are possible on request)�

» A voltage of 4��30 VDC must be applied to the RESET input for more than 100

ms to set the current position to 0�

The RESET input has no influence on the incremental signals.

The RESET input has no influence on the speed switch.

If a voltage of 4��30 VDC is applied to the RESET input during the initialization

phase after switching on, the delay time of 100 ms does not begin until after the

initialization phase�

5.2.3

Function „Rotating direction"

The function „rotating direction" (DIR input) reverses the rotating direction of the SSI

signal�

» A voltage of 4��30 VDC must be applied to the DIR input for more than 100 ms

to reverse the current rotating direction of the SSI signal� For the duration of

the applied voltage of 4��30 VDC, the rotating direction of the SSI signal is then

reversed�

The DIR input has no influence on the incremental signals.

The DIR input has no influence on the speed switch.
