Cautions
The DMR 50-50/50 servo drive contains hot surfaces and electrically-charged
components during operation.
The maximum DC power supply connected to the instrument must comply with
the parameters outlined in this guide.
The DMR 50-50/50 servo drive must be connected to an approved 24VDC
auxiliary power supply through a line that is separated from hazardous line
voltages using reinforced or double insulation in accordance with approved
safety standards.
The DMR 50-50/50 series is designed to gets its power from a 48 VDC power
source. Power to this device must be supplied by DC voltage, within the
boundaries specified for the DMR. High voltages may damage the drive. The
DC power supply voltage range is defined in this manual. Safety margins must
be considered in order to avoid activating the under or over-voltage protection
against line variations and/or voltage drop under load. The transformer should
be able to deliver the required power to the drive (including peak power)
without significant voltage drops (10% maximum). While driving high-inertia
loads, the power supply circuit must be equipped with a shunt regulator;
otherwise, the drive will be disabled whenever the capacitors are charged
above the maximum voltage
Before switching on the DMR, verify that all safety precautions have been
observed and that the installation procedures in this manual have been
followed.
