Terminal 37 Safe Stop Function
The FC 202 is available with optional safe stop
functionality via control terminal 37. Safe stop disables the
control voltage of the power semiconductors of the
frequency converter output stage which in turn prevents
generating the voltage required to rotate the motor. When
the Safe Stop (T37) is activated, the frequency converter
issues an alarm, trips the unit, and coasts the motor to a
stop. Manual restart is required. The safe stop function can
be used for stopping the frequency converter in
emergency stop situations. In the normal operating mode
when safe stop is not required, use the frequency
converter's regular stop function instead. When automatic
restart is used – the requirements according to ISO
12100-2 paragraph 5.3.2.5 must be fulfilled.
Liability Conditions
It is the responsibility of the user to ensure personnel
installing and operating the Safe Stop function:
