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
MP_kvFactor
