X7 connector
X7. Status of the safety relay
Connector of the compact drive associated with the second contact (N.C.,
Normally Closed) of an internal safety relay (with guided contacts). The
status of the relay (initially closed) may be acknowledged through the two
pins and a CNC, PLC or control panel, i.e. that the relay has actually
opened or closed. These two terminals are identified at the drive as AS1-
AS2. The opening or closing of this relay depends on whether 24 V DC
are present or not at pin 2 “Drive Enable” of control connector X2. For fur-
ther detail on this connector, see
9.2. Interface section of chapter 9.
