Data transfer
Clock
Data
Clock frequency 100 kHz���2 MHz
Monoflop time (t) 20 µs (internal)
n, m Number of bits
i
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�
i
The RESET input has no influence on the incremental signals.
The RESET input has no influence on the speed switch.
i
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�
i
The DIR input has no influence on the incremental signals.
The DIR input has no influence on the speed switch.
