General; Safety Information - Siemens Sinamics G130 Operating Instructions Manual

General

The VSM10 Voltage Sensing Module is used for acquiring the voltage characteristic on the
motor side, so that the following functions can be implemented:
● Operation of a permanent-magnet synchronous motor without encoder with the
requirement to be able to connect to a motor that is already rotating ("flying restart"
function).
● Fast flying restart of large induction motors: The time for the demagnetization of the motor
is eliminated as a result of the voltage sensing.
When operating a permanent-magnet synchronous motor without encoder, the "Flying
restart" function must be activated with p1200.

Safety information

Non-observance of the fundamental safety instructions and residual risks
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Fire through overheating due to insufficient ventilation clearances
Insufficient ventilation clearances result in overheating with danger to persons as a result of
smoke and fire. This can also result in more downtimes and reduced service lives of the
Voltage Sensing Module.
• For this reason, it is imperative that you maintain the 50 mm clearances above and
NOTICE
Destruction of the VSM10 as a result of voltage measurements incorrectly carried out
If the voltage measurement is carried out incorrectly, the VSM10 can be destroyed as a
result of the high voltage stress across the insulating clearance.
• When using long motor cables, it is not permissible that the output voltage of the Power
