17 Checking the enables on the iTNC 530 HSCI
17.1 Introduction
For an operating axis (axis in control loop / being positioned) ...
 no "Axis clamped" symbol is shown
 the "STIB" asterisk (control-in-operation) is visible
 the feed rate display must not be highlighted
 the position display (ACTL, NOML) changes when the axis moves
The appropriate enables are required in order to work with axes or spindles.
If one or several enables are missing, an error message is output or the axes and/or the spindles
cannot be operated.
The following conditions must be fulfilled to drive axes and spindles:
EMERGENCY STOP
chain
The EMERGENCY STOP chain must be closed.
The EMERGENCY STOP chain includes ...
 the EMERGENCY STOP button on the machine operating panel
 the EMERGENCY STOP button on the handwheel (if available)
 hardware axis limit switches (if available)
 the iTNC 530 HSCI itself (through a PLB 62xx system module or a UEC 11x controller unit)
The "Control is ready" output of the iTNC 530 HSCI switches, for example, a relay whose contacts are
part of the EMERGENCY STOP chain.
In the event of severe errors (e.g. defective encoder), the iTNC 530 HSCI resets the "Control is ready"
output and thus interrupts the EMERGENCY STOP chain.
The precondition is that the machine manufacturer has correctly integrated the "Control is ready"
output and input into the EMERGENCY STOP chain.
