Definition of currents
On axes:
 In

“Continuous duty cycle” current.
 Ip

Peak current.
See load duty cycles.
On spindles:
 In

“Continuous duty cycle” current.
 IS6-40%

Current that, in an intermittent duty cycle S6 with 10 min-
ute cycle, circulates for 4 minutes with load (the other 6 minutes oper-
ates without load); in other words with magnetizing current = 0.7 x
rated current In).
 Imax

Maximum peak current.
See load duty cycles.
Note. The values of these currents are given in RMS.
F. H3/85
Load cycle S1 with current peak.
F. H3/86
Load cycle S6-40.
F. H3/87
Load cycle S6 with current peak.
