Electric peak power (worst-case value for dimensioning the supply unit)
S1 Continuous operation characteristic of the motor (according to EN
60034-1; 1998), natural convection
S3 Intermittent duty characteristic with 25% ED of the motor (according to
EN 60034-1; 1998) and max. cycle duration 1 min
① Mmax Rexroth IndraDrive Mi, controlled infeed DC 750 V
②-④ Mmax Rexroth IndraDrive Mi, uncontrolled infeed 3 × AC 400 V. The
voltage drop on the supply line has not been taken into account. With a
high degree of voltage drop on long motor lines, we have inflected peak
torque characteristics ①-④ at lower speeds. See chapter "Allowed Ca‐
ble Lengths"
