Safety-related brake mounted on a motor not intended for the purpose
It is not permitted to retrofit a safety-related brake.
The safety-related brake is mounted on a SIMOGEAR geared motor with the appropriate
version. The geared motor with safety-related brake must be ordered in this specific version
and must not be retrofitted by the user, as otherwise functional safety is not obtained.
Functional safety without evaluating thermal motor protection
SIMOGEAR geared motors with safety-related brakes are equipped with thermal motor
protection, which must be evaluated.
The commissioning engineer must connect the temperature sensor to the converter system.
Operation without evaluating the motor temperature sensor is not permissible.
Resonance effects in operation
Resonance effects can occur on the geared motor as a result of the frequency converter or
comparable power controlling devices.
Resonance effects must be excluded.
Optimize, for example, the control parameters by appropriately filtering the current
setpoint.
Siemens AG takes responsibility for compliance with functional safety specifications relating
to the supplied geared motor with safety-related brake and SINAMICS S120. The safety-
related connecting elements are sealed before delivery.
Take into account the applicable national and regional legislation, standards and regulations.
To ensure that the geared motor is not damaged:
• Do not step on the geared motor.
• Do not place any objects on the geared motor.
• Do not place the geared motor down on the fan cover.
