3.3 During Operation
During operation, the iTNC 530 monitors the following positions:
Amplitude of encoder signals
Edge separation of encoder signals
Absolute position for encoders with distance-coded reference marks
Current position (position or servo-lag monitoring)
Actual path traversed (movement monitoring)
Position deviation at standstill (standstill monitoring)
Nominal speed value
Checksum of safety-related functions
Power supply
Buffer battery voltage
Operating temperature of MC and CPU
Run time of PLC program
With digital axes, the iTNC 530 also monitors:
Motor current
Motor temperature
Temperature of power module
Dc-link voltage
I
2
t of power module and motor
Depending on the PLC program, the following can be evaluated:
Actual utilization of drive motors
Status of HEIDENHAIN Inverters
If the Control is ready signal output and the Control is ready signal acknowledgment input
are correctly connected to the emergency-stop loop, the control interrupts the loop via the
Control is ready signal output as soon as a hazardous error occurs.
