- Compact and book format for integration in a variety of different cabinet types 
- Integrated safety function for compliance with functional safety standards 
- Enhanced resistance to polluted atmospheres

By taking account of constraints on product setup and use right from the design stage, Schneider Electric simplifies the integration of the Altivar Machine ATV320 drive into industrial machines. It features more than 150 functions. It is robust, easy to install, and compliant with the Machinery Directive 2006/42/EC. ATV320 is fully integrated inside Schneider Electric’s EcoStruxure Machine through DTM. PLCopen-compliant libraries. SoMachine can be used to develop, configure, and set up an entire machine in a single software environment. Using FDT/DTM technology, it is possible to configure, control, and diagnose Altivar Machine ATV320 drives directly in SoMachine and SoMove software by means of the same software brick (DTM). With seamless integration under this platform, Altivar Machine ATV320 benefits from the advantage of shorter engineering and design times. Optional Ethernetbased communication capability makes it accessible to production data at any level of automation system.

Integrated safety functions of Schneider Electric vfd Altivar Machine ATV320 series

Safe Torque Off (STO) safety function
This function brings the machine safely into a no-torque state and/or prevents it from starting accidentally.

Safely Limited Speed (SLS) safety function
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
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
This function prevents the speed of the motor from exceeding the predefined speed limit.
- 2 different speed limits can be defined and can be selected by logic inputs. 
- If the motor speed exceeds the predefined speed limit value, safety function STO is triggered.
Once the SMS function is configured, it is continuously active.

Guard Door Locking (GDL) safety function
This function allows you to release the guard door lock after specified delay when the motor power is turned off. The specified delay is chosen 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.
