MC4U Control Module Table 40 Hardware Guide Drive Protection Circuits Protection Type LDM3U-55V-8A LDM3U-55V-16A Short current (phase-to-phase Iin >10A±5% and phase to ground) Iin >20A±5% T_heatsink > 95 - 100oC Over temperature T_heatsink > 95 - 100oC Note The software does not enable the display of an undervoltage warning message. Table 41 provides the dynamic braking specifications for the LDM3U.
