Resolution
With parameter 65 the resolution of TNC 15l/TNC 155 can be programmed for either 1 urn or 5 pm.
For optimization of machine parameters, 1 urn is used. The 5 pm resolution is usually sufficient for normal
machine operation.
Signal evaluation
X 12
A
1 - 20-fold max. traversing
Y 13
speed 16 [m/min]
Z
14 2
4 =
1 O-fold max. traversing
IV 15
speed 12 [m/min]
With these parameters, the signal evaluation for the transducers can be reduced from 20-fold to 1 O-fold.
Please note:
With IO-fold subdivision the max. traversing speed is 12 m/min (input frequency of control 20 kHz).
Standstill supervision 169
0,001 . 30 [mm]
-i------
Parameter 169 determines the range in which non-controlled axes may move without activition of a fault
detection signal. If the programmed limitation is exceeded, the control then goes into an emergency stop
condition and indicates the flashing message GROSS POSITIONING ERROR.

Movement supervision
234
T
0.03.. 10 Cvl
Parameter 234 monitors machine movement when the programmed voltage is output. If no movement
takes place, the control goes into the emergency stop condition and indicates the flashing message
GROSS POSITIONING ERROR.

Parameter 170 determines whether the control is intended as an off-line programming station or not. If
parameter 170 is programmed with 1 or 2, the control requires no transducers or external circuitry.

Program conditions are indicated in the status display of the TNC 151/TNC 155. These status data are required
for re-entry into an amended contour after an operational interruption. If these program status data are to be
cancelled at the end of the program, MP173 should be programmed with "1".
