factor, feed rate,
and following error
The following formula shows the interrelation of k
v
factor, feed rate, and
following error:
or
k
v
= kv factor [(mm/s)/mm]
v
e
= rapid traverse [mm/sec]

Note
The unit for the kv factor of the MANUALplus 620 differs from the one used
for the other TNC contouring controls, such as the iTNC 530.
Unit for the kv factor of the MANUALplus 620: mm / (mm · s)
Unit for the kv factor of the iTNC 530: m / (mm · min)
Therefore:
iTNC 530 kv factor · 1000 / 60 = MANUALplus 620 kv factor
