Terminal 37 Safe Stop Function
The AF-650 GP and is available with safe stop functionality
via control terminal 37. Safe stop disables the control
voltage of the power semiconductors of the adjustable
frequency drive output stage which in turn prevents
generating the voltage required to rotate the motor. When
the Safe Stop (T37) is activated, the adjustable frequency
drive 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 adjustable frequency drive in
emergency stop situations. In the normal operating mode
when safe stop is not required, use the adjustable
frequency drive'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
