Variable speed drives

Altivar Machine ATV320

Integrated safety functions (1)

Altivar Machine ATV320 drives include 5 safety functions:

STO: Safe Torque Off (2)

SLS: Safely Limited Speed

SS1: Safe Stop 1

SMS: Safe Maximum Speed

GDL: Guard Door Lock

These functions are certified in accordance with IEC61508 Ed.2 "Functional safety

of electrical/electronic/programmable electronic safety-related".

These integrated functions make it possible to:

Simplify setup of machines that require a complex safety related device

Improve performance during maintenance by reducing machine or installation

downtime

Note: Some applications may require the addition of external Preventa safety modules (2).

Safe Torque Off (STO) safety function (1)

This function brings the machine safely into a no-torque state and/or prevents it from

starting accidentally.

Safely Limited Speed (SLS) safety function (1)

The SLS integrated safety function can be initiated by activation of safety function

inputs. This function prevents the motor from exceeding the specified speed limit. If

the motor speed exceeds the specified speed limit value, safety function STO is

triggered.

Safe Stop 1 (SS1) safety function (1)

The SS1 integrated safety function causes a category 1 safe stop.

This function monitors the deceleration according to a dedicated deceleration ramp

and safely shuts off the torque once standstill has been achieved.

Safe Maximum Speed (SMS) safety function (1)

This function prevents the speed of the motor from exceeding the pre-defined speed

limit.

2 different speed limits can be defined and can be selected by logic inputs.

If the motor speed exceeds the pre-defined speed limit value, safety function

STO is triggered.

Once the SMS function is configured, it is continuously active.

Guard Door Locking (GDL) safety function (1)

This function allows you to release the guard door lock after specified delay when

the motor power is turned off. The specified delay is choosen according to the type

of stop.

The front door of the machine can be opened only after the motor is stopped, this

function helps to ensure the safety of the machine operator.

Setting up the integrated safety functions (1)

Setting up the integrated safety functions in the Altivar Machine ATV320 drive does

not require any options or additional accessories.

The functions are connected directly to the drive’s digital inputs and can only be

configured using SoMove setup software.
