AC30V series Variable Speed Drive
Examples of wiring to X10/05 and X10/06
.
Active high output: Active low output:
The load is energised and X10/05 is high when STO is in the
intended safe STO state. The load is energised and X10/06 is low when STO is in the intended
safe STO state.
The examples show the use of the 24V supply provided on X12/05 (+24V) and X12/06 (0V) as source of power to a load. Alternatively an external 24V
supply could be used.
Note: If a drive is powered from 24V only, i.e., 24V is applied to terminals X12/05 or X12/06 and the 3 phase power is off, the STO user output will still
reflect the status of the two STO user inputs.
