11.1.2 Metallic, large area connections
• Make a large-area, electrically conductive connection between all metallic components
(equipment housing of the PMCprimo Drive2, filter housing, motor housing, screen braid of the
cables) and a star point (mounting plate).)
• Avoid using coated surfaces such as Eloxal or yellow-chroming (rails, screws). These can have
very high frequency-dependent impedances (skin effect).
11.1.3 PE connection, earthing, grounding
PE connections as per VDE 0100 or EN 60204 are dimensioned purely for the protection against
contact voltage and dangerous body currents.
• Connect the PMCprimo Drive2 to the EMC ground by a short connection with a large surface
area (braided band) to ensure low lead inductance.
• Wire the PE connection for the individual system components in a star connection to the
potential equalization rail
• Connect all metal parts with the PE rail
11.1.4 Motor choke
A motor choke damps the slew rate of the motor current (reducing the speed of the switching
edges), thus reducing the current that is produced in the screen
• motor chokes makes it possible to use longer motor cables
• reduced load on the PMCprimo Drive2 output stages and rectifiers
• reduced stress on the insulation of the motor windings
You can order a special motor choke from us.
