19.9 Safe Speed Monitor (SSM)
The funcon monitors the limited speed set.
The funcon is acvated if:
•
the monit
oring limits are parameterised, or
•
the values are non-zero.
WARNING!
A safety-rated encoder system must be used.
Without an enc
oder, this safety funcon cannot be used.
▶
Apply a safety-rated encoder system to use this funcon.
NOTICE
The SSM funcon does not feature any hysteresis.
Oscillang response of the safe output during operaon in the proximity of the speed limit

During operaon within the limit values, the SSM status is set on the safety bus within the
limits 0x2870:0020x2870:002.
The SSM status is assigned to the safe output as safe speed monitor (amount)
0x28B2:0010x28B2:001.
If the amount of the safe speed adopts the value "0", the SSM funcon is deacvated.
The status bit in 0x28B30x28B3 inuences the control of available outputs.
