n A maximum of 10 variables can be used in the description tables for the
tilting-axis geometry.
n Numbers in hexadecimal and binary form in freely definable tables
n New error messages for FN14
n M4587: Feed rate limit not effective
n During powerfail: Attempt to reset PLC outputs and to maintain readiness
for 3 seconds
n FN17 ID600: Factor for velocity semifeedforward
n FN17 ID600: Factor from MP1396 for velocity semifeedforward
n FN18 ID20: Coordination between logical and geometrical axis
n FN18 ID310: M144 active

n Module 9061: Status of non-modal M functions
n Module 9066: Status of HEIDENHAIN inverter
n Module 9133: Temperature of the LE
n Module 9279: Control reset
n M144: When an axis is moved, the kinematics are recorded in the display,
but without compensatory motions.
n Increased protection of the controls from unauthorized data accessing
n If the hardware contains flash EPROMs, the letter “F” is displayed before
the NC software Id. Nr.
n When transferring an actual position capture to a datum table, it can be
referenced to either the workpiece datum or the machine datum.
n When transferring measured values from the manual touch probe cycles to
a datum table, they can be referenced to either the workpiece datum or the
machine datum.
