Definition of currents
On axes
 IN  “Continuous duty cycle” current.
 Ip
 Peak current, Imax.
See load duty cycles.
On spindles
 IN  “Continuous duty cycle” current.
 I
S6-40%  Current that, in an intermittent duty cycle S6 with 10 minute
cycle, circulates for 4 minutes with load (the other 6 minutes operates
without load); in other words with magnetizing current = 0.7 x rated
current I
N).
See load duty cycles.
 I
S3-5%  Current that, in an intermittent duty cycle S3 with 10 second
cycle, it works at constant current IS3-5% (2xIN) for 0.5 second and it
works at rated current for 9.5 second.
See load duty cycles.
NOTE. The values of these currents are given in RMS.
