xt derating for ARS 2320W and ARS 2360W
For these two servo drives it is necessary to calculate a derating for the duration of the maximum
current as a function of the pulse frequency (f
PWM
) and the electrical rotational frequency in the
firmware. The following figure shows the 4 essential set points.
