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:

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.

If feedback systems for safety functions are used, the manufacturer’s
documentation must be observed!
