4. Basic operation of device
The description of the various basic operations relates to the DEFAULT configuration when shipped using the
speed detection function. The following safety operations are performed:
Continuous measurement of the speed of the drive to be monitored
-
Exceedance of maximum speed SMS (Parameter P303) immediately trips STO
-
-
Drive speeds greater than Zero Speed (Parameter P301) enable the protective interlock.
The control inputs SS1, SLS and Door extend these safety operations:
Controlled slowdown of drive by enabling frequency converter ramp function
Alternation of maximum speed to be monitored
Detection of open protective devices
The way the outputs react to system and application faults is described in the Chapter entitled "Fault monitoring".

Operation of inputs
With the exception of FBC, all inputs are read in dual channel format. Contact-based signallers with NC operation
and test signal-based power in the DEFAULT configuration are used by the module.
