Overcoming an issue with the DS402 protocol on the AMI8121-3100-0F21 motor

1 Problem
2 Solution

Problem

The specification of the GY and GZ motors on A2032 and A2033 included a TwinSAFE system, which makes it difficult to operate within a non-TwinSAFE environment.

Beckhoff have a solution to this, which is to use the TwinSAFE logic controller contained inside the AMI motor / drive to control its own STO "always on"

However

There is a problem with the particular spec of the AMI8121-3100-0F21 - the 2 denotes a DS402 communication interface profile. This profile needs a firmware update to enable the TwinSAFE communication.

Solution

...The safety project defined in the following steps is saved on the Software Updates board. The following steps are for reference and for recreating this project - IT DOES NOT NEED TO BE DONE EVERY TIME

The solution takes the following steps:

Ensure the TwinCAT environment is up to date
Ensure the latest ESI (device description tables) are downloaded
Ensure the latest Drive Manager 2 Installed

Update EEPROM Driver

Device
Online Tab
Right click on the AMI->Write EEProm
Pick AMI8000-0100-0020
Activate Configuration
PowerCycle the AMI Motor
Device Manager may need changing to the new type
Drive Manager needs to detect changes

Create the Safety Project

Add new Safety Project with preconfigured Input
Target System - Link to safety PLC on correct axis
Alias Devices->Add AM891x
Create the safeOr in TwinSafeGroup
Connect back on itself as per diagram

OrIn1 is a break contact
Assign the variable name AlwaysTrue to orOut
Change the linking mode of the AMI to "Local"

Variable Mapping

AlwaysTrue to AMI891x as diagram
PLC Outputs
- bErrAck -> ErrorAcknowledgement.sds
- bSafetyRun->Run.sds
