Additional conditions for operation at low output frequencies:
• The output current reduction does not apply to acceleration from zero speed if an output
frequency of >10Hz is reached within 100ms. A reduction of the output current must be
taken into consideration if, at frequencies <10 Hz, the operating time exceeds 2 % of the daily
operating time.
• For drive systems with induction motors (with slip frequency), the permissible continuous
load at zero speed (e.g. suspended axis without counterweight or travel to xed stop):
– 50% of In for C type Motor Modules with a pulse frequency ≥4kHz
– 65% of In for C type Motor Modules with a pulse frequency ≥2.5kHz
8.4.7 Mounting the Motor Module
Overview
Motor Modules are designed for installation in the control cabinet. They are xed to the control
cabinet panel or a mounting panel.
Requirement
WARNING
Risk of injury as a result of foreign bodies in the device
Parts (e.g.: drilling chips, end sleeves) falling into the device can cause short-circuits and
damage the insulation. This can result in severe injury (arcing, loud bang, parts that are ung
out).
• Only perform installation and other work when the devices are current-free.
• Cover the ventilation slots when mounting and installing the control cabinet and remove
the cover before switching on.
NOTICE
Overheating due to inadmissible mounting position
Components can overheat and therefore be damaged if mounted in an inadmissible position.
Overheating can cause malfunctions.
• Only mount components in a vertical mounting position with the DRIVE-CLiQ connection at
the top in the control cabinet.
• Keep the ventilation clearances above and below components free and unobstructed.
