The ARS 2100 SE series servo drive also features a sine modulation or alternatively a sine modulation
with third harmonic. This increases the effective converter output voltage. The type of modulation can
be selected via the Metronix ServoCommander
®
. The default setting is sine modulation.
If the sine modulation with third harmonic is used, the controllable upper motor speed
limit increases due to the higher control reserve of the PWM output stage.
