Securing functional safety
2.1 General information
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 Encoders for Functional Safety from the Kübler company.
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.
Resonance effects in operation
Resonance effects can occur as a result of the converter or comparable power controlling
devices.
If you optimize the controller parameters, e.g. using the appropriate current setpoint
filtering, then you can rule out resonance effects such as these.
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 (Page 22). ...then lower ....for the brake than for
standard applications apply, see...
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.
