Output voltage as a function of speed: M202
Behavior with M202
The TNC outputs the voltage as a function of speed. In the machine
parameters, the machine tool builder defines up to three characteristic
curves FNR in which specific feed rates are assigned to specific
voltages. Use miscellaneous function M202 to select the curve FNR
from which the TNC is to determine the output voltage.
Input range: 1 to 3
Effect
M202 remains in effect until a new voltage is output through M200,
M201, M202, M203 or M204.
Output voltage as a function of time (time-
dependent ramp): M203
Behavior with M203
The TNC outputs the voltage V as a function of the time TIME. The
TNC increases or decreases the current voltage linearly to the value
programmed for V within the time programmed for TIME.
Input range
Voltage V: 0 to 9.999 Volt
TIME: 0 to 1.999 seconds
Effect
M203 remains in effect until a new voltage is output through M200,
M201, M202, M203 or M204.
Output voltage as a function of time (time-
dependent pulse): M204
Behavior with M204
The TNC outputs a programmed voltage as a pulse with a
programmed duration TIME.
Input range
Voltage V: 0 to 9.999 Volt
TIME: 0 to 1.999 seconds
Effect
M204 remains in effect until a new voltage is output through M200,
M201, M202, M203 or M204.
