MDD 121-1
Page 12 10.03.2021
• Power supply modules MDP101-1 and MDP 102-1 are to be used
with axis modules MDD111-1 and MDD121-1 only.
• Drives must to be used with motors provided with over temperature
sensing.
2.6 Non-prescribed use
“Prescribed use” means, that the servo drive system is used according to the environmental
conditions described in this documentation.
• It must not be used in electrical equipment on ships (service afloat)
or in offshore applications because of the conductive pollution.
• It must not be used in environmental conditions that do not meet the
conditions described in this documentation (too hot, without closed
switchgear cabinet, wrong mounting position, etc.)
Be very careful in plants, were conductive material (carbon fiber, graphite with machining of
graphite cast iron or similar) is easily purgeable in the factory floor. In this case, the
switchgear cabinet has to be sealed very carefully (no forced ventilation with blower filter) or
be placed outside the factory floor. Especially during start-up of the machine, the risk is high
because of open switchgear cabinet doors. Servo drives, which become contaminated,
cannot be used anymore.
