Voltage output
varies with the
velocity: M202 FNR
The iTNC outputs the voltage as a function of the velocity:
In MP3013.x and MP3014.x, define up to three characteristic curves in a
table.
In the table, certain analog voltages are assigned to certain feed rates:
With M202 FNR select the curve in which the iTNC finds the voltage to be
output.
Input: 1 to 3
Duration of effect: M202 FNR is effective until a new voltage is output with
M200 to M204.
You can enter up to four kink points per curve in the table. The values to be
distributed are interpolated linearly between the kink points. The first kink
point must start with the input value zero. For the following kink points of the
curve the input values must rise steadily. The iTNC detects the beginning of a
new curve from the input value zero.
Example:
MP3013.x Characteristic curve kink points (velocity) for output of the
analog voltage with M202
Input: 10 to 300 000 [mm/min]
MP3014.x Characteristic curve kink points (voltage) for output of the
analog voltage with M202
Input: 0.000 to 9.999 [V]
