This chapter describes the operation of the Q950: Prevention of unexpected start-
up and instructs how to wire and use it.

Overview

The Q950 uses the FSO-12 safety functions module (Q973) or the 
FSO-21

 

safety functions module (Q972) for the Prevention of unexpected start-up 

(POUS) safety function. ABB installs the FSO modules to the inverter units and sets 
default parameter values for the option at the factory. The user installs and wires an 
operating switch and an indication lamp (optional) on site. These are not included in the 
delivery.

When safety pulse encoders are used in the safety application, also the FSE-31 pulse 
encoder interface modules (L521) are installed in the inverter units. ABB installs 
the FSE modules to the inverter units and sets the delivery configuration for the cabinet 
safety option at the factory.

The user activates the POUS function with an operating switch mounted, for example, on 
a control desk. When the switch is open (off), the POUS function is active and the POUS 
indication lamp is on.

When the user switches off the POUS switch, he/she actually activates the Safe torque off 
(STO) function in the inverter unit.

 

The STO function disables the control voltage of the 

power semiconductors of the inverter unit output stage. This prevents the inverter unit from 
generating the torque required to rotate the motor(s). With this function, the user can do
