7 Safety engineering

Motor−encoder combinations

Drive systems with Servo Drives 9400 and safety module SM301 provide speed−dependent

safety functions for safe speed monitoring and/or safe relative−position monitoring.

Observe permissible motor−encoder combinations during configuration.

ƒ Possible speed−dependent safety functions with safety module SM301:

– Safe stop 1 (SS1)

– Safe operational stop (SOS)

– Safely limited speed (SLS)

– Safe maximum speed (SMS)

– Safe direction (SDI)

– Safe speed monitor (SSM)

– Safely limited increment (SLI)

ƒ Permissible motor−encoder combinations for these functions:

Resolver RV03

Two−encoder concept Up to PL e / SIL 3

A "two−encoder concept" includes e.g. a resolver as motor encoder and, at the same time,

an absolute value encoder (sin/cos), an incremental encoder (TTL), or digital encoder

(SSI/bus) as position encoder on the machine.

In the case of the "2−encoder concept", the achievable risk mitigation (PL/SIL) depends on

the suitability of the encoders used.

 Note!

If feedback systems for safety functions are used, the manufacturer’s

documentation must be observed!
