Warning
Despite the “Axis disable” command via terminal 663, dangerous voltages may
still be present at the drive control output terminals.
The “Axis disable” command via terminal 663 is not suitable for electrical isola-
tion or for use as a drive deactivation mechanism.
The following signals must be made available at the PLC interface for axis or
spindle:
NST “Controller enable” (DB31–61, DBX2.1)
NST “Pulse enable” (DB31–61, DBX21.7)
NST “Position measuring system 1 or 2” (DB31–61, DBX1.5, DBX 1.6)
The following signals on the interface must not
be set or else the axis/spindle
motion will be disabled:
NST “Feed/spindle correction switch” (DB31–61, DBB0) not set to 0%
NST “Axis/spindle disable” (DB31–61, DBX1.3)
NST “Adjustment mode” (DB31–61, DBX1.4)
NST “Remaining distance/spindle reset” (DB31–61, DBX2.2)
NST “Feed stop/ spindle stop” (DB31–61, DBX4.3)
NST “Travel button disable” (DB31–61, DBX4.4)
NST “Power-up sensor disable” (DB31–61, DBX20.1)
