7.1 Safety instructions for Motor Modules Booksize Compact
NOTICE
Device failure as a result of unshielded or incorrectly routed cables to temperature sensors
Unshielded or incorrectly routed cables to temperature sensors can result in interference
being coupled into the signal processing electronics from the power side. This can result in
significant disturbance of all signals (fault messages) up to failure of individual components
(destruction of the devices).
• Only use shielded cables as temperature sensor cables.
• If temperature sensor cables are routed together with the motor cable, use separately
• Connect the cable shield to ground potential at both ends through a large surface area.
• Recommendation: Use suitable Motion Connect cables.
Note
Operating motors with a built-in holding brake
A regulated DC power supply is required to operate motors with a built-in holding brake. The
voltage is supplied via the internal 24 V busbars.
• Take note of the motor holding brake voltage tolerances (24 V ± 10%) and the connecting
cable voltage drop.
• Set the DC power supply to 26 V. This ensures that the supply voltage for the brake
remains within the permissible range when the following conditions are fulfilled:
– Siemens three-phase motors must be used
– Siemens MOTION-CONNECT power cables must be used
– Motor cable lengths, max. 100 m
NOTICE
Damage through use of incorrect DRIVE-CLiQ cables
Damage or malfunctions can occur on the devices or system when DRIVE-CLiQ cables are
used that are either incorrect or have not been approved for this purpose.
• Only use suitable DRIVE-CLiQ cables that have been approved by Siemens for the
Note
Malfunctions due to polluted DRIVE-CLiQ interfaces
Malfunctions can occur in the system through the use of polluted DRIVE-CLiQ interfaces.
• Cover unused DRIVE-CLiQ interfaces with the supplied blanking covers.
