12 Introduction to the manual
Option description
Contents of this chapter
This chapter describes the +Q952 emergency stop option and its settings.
Overview
The option +Q952 corresponds to a controlled stop in accordance with stop category 1
(EN/IEC 60204-1). After the user has given the emergency stop command, the drive first
decelerates the motor(s) to zero speed according to a preset ramp time. Then, the drive
trips the main contactor/breaker which cuts off the input power of the drive.
For the option +Q952, ABB installs the FIO-01 digital I/O extension module (option +L501)
to the drive control board (Slot 1).
Note: Drives with the Prevention of unexpected start-up (POUS) option (+Q957): If the user
activates the POUS function during the emergency stop deceleration ramp, it overrides the
emergency stop function. This activates the Safe torque off (STO) function of the drive
immediately and the motor coasts to a stop. For more information on the POUS safety
function, see Prevention of unexpected start-up (option +Q957) for
ACS880-07/17/17LC/37/37LC drives (3AUA0000119910 [English]).
The design principles of the option +Q952 comply with EN ISO13850.
For a list of related standards and European directives, see section Related standards and
directives.
Operation principle
The figures show a simplified operation principle. Implementation of main contactor/breaker
and charging circuit can vary depending on the product. For a more detailed description,
see the circuit diagrams delivered with the drive.

The contact of the auxiliary relay [K62.2] energizes the emergency stop reset button indicator light
[S62].

Normal operation resumes after the user:
7
• releases the emergency stop button [S61] to normal (up) position
• resets the emergency stop circuit with the emergency stop reset button [S62] (the user must push
the button for 0.1 - 3 seconds)
• resets the drive (if the drive tripped on a fault).
If the supply unit has an operating switch, it must be switched to position 0 and back to position 1 to
restore the start mode (default).
