Maximum feed rate by
way of:
Maximum signal frequency of the position encoder:
 At 1 V
PP
: 27 kHz or 400 kHz
 At 11 µA
PP
: 27 kHz or 140 kHz
Calculation of the maximum feed rate Fmax:
F
max
: Maximum feed rate [m/min]
f
max
: Maximum signal frequency of position encoder [kHz]
SP: Signal period of the position encoder [kHz]
Example:
F
