Operating Instructions, 07/2021, A5E50553480A/RS-AB
WARNING
Functional safety without motor protection evaluation
The motor with functionally safe rotary encoder is equipped with thermal motor protection,
which must be evaluated.
Use the geared motor with motor protection evaluation.
WARNING
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 through an appropriate setpoint filtering.
Siemens AG takes responsibility for compliance with functional safety specifications relating
to the supplied geared motor with DRIVE-CLiQ rotary encoder and SINAMICS S120. The
safety-relevant connection elements are sealed before delivery.
Take into account the applicable national and regional legislation, standards and regulations.
If a geared motor with a DRIVE-CLiQ rotary encoder is used for safety-relevant applications
together with a brake, lower maximum permissible air gaps for the brake apply than for
standard applications, see Technical specifications of the brake for encoders for functional
safety (Page 25).
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.
Working on the rotary encoder and the brake
All safety-related mechanical connections for the rotary encoder or the brake are marked with
a seal (enamel dot).
Only Siemens service personnel or personnel trained and authorized by Siemens are
permitted to carry out the work.
