AS-i data for SaW slaves (VBA-2E-KE4-ENC-S )

A safety signal is output (code sequence generated) when the frequency falls be-
low the set threshold.

Information!
f is the set upper limit for the safety frequency range, f
max
the unit (250 kHz).
Information!
0-sequence can be enforced in the diagnostic slave via the DO2.
The speed monitor offers the following settings for SaW slaves:
• Represent multiple signals as a collective message on just one SaW input
slave
• Any number of safe signals acts on up to eight SaW input slaves (input slaves
for each channel: safe speed, safe stop, right- and left-rotation).
