YASNAC PCNC Programming Manual Chapter 1: Programming Basics
When using the F1-digit feed function, it is possible to optimize the selected feedrate by turning
the manual pulse generator while the F1-DIGIT switch is ON. Increase or decrease of increments
per pulse (F1-digit multiply) should be set for the parameters indicated in Table 1.2.3.2.
Table 1.2.3.2: Parameter Numbers Used for Setting F1-digit Multiply for the para
Note: Value “1”= 0.1 mm/min per pulse
If increase/decrease increments per pulse is set for these parameters, the value set for the parame-
ters in Table 1.31 is updated in response to the manual pulse generator operation.
Parameters indicated in Table 1.33 are used to set the upper limits of the feedrate for F1-digit fee-
drate selection. If a value larger than the allowable maximum feedrate set for parameter pm2800
is set, it is disregarded and replaced with the value set for pm2800.
Table 1.2.3.3: Parameters pm2865 and pm2866
1. When the 1-digit numerals are set to the parameters pm0802 to pm0828, and pm2004 D0
= 0, feedrate on the screen is displayed as “0”. However, the machine moves in units of
0.1 to 0.9mm/min or 0.01 to 0.09 inch/min.
2. If “F0”is specified, alarm “0370” occurs.

Parameter Numbers Description
pm2865 Allowable maximum feedrate for F1 to F4
pm2866 Allowable maximum feedrate for F5 to F9
pm2004 D0 = 0
Feedrate at the deceleration of 0.001mm or 0.0001 inch is F6.0
mm/min or F4.1 inch/min.
pm2004 D0 = 1
Feedrate at the deceleration of 0.001mm or 0.0001 inch is F6.1
mm/min or F4.2 inch/min.
