WARNING
Functional safety without safety-relevant encoder evaluation
The encoder is only safety-relevant when used in conjunction with a suitable encoder
evaluation unit.
Use the encoder together with a safety-relevant encoder evaluation unit. Especially observe
the requirements relating to suitable, safety-relevant encoder evaluation in the operating
instructions Sendix SIL Rotary encoders for Functional Safety from the Kübler company
WARNING
Functional safety without motor protection evaluation
The motor with functionally safe 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 converter or comparable
power controlling devices.
Resonance effects must be excluded.
Optimize, for example, the controller parameters through an appropriate setpoint filtering.
For the geared motor with the encoder, Siemens AG assumes responsibility that the directives
of functional safety are complied with. The safety-relevant connection elements are sealed
before delivery.
Also take into account the applicable national and regional legislation, standards and
regulations.
If a geared motor with encoder is used for safety-relevant applications together with a brake,
then 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 22).
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.
