Replacing a Faulty Servodrive

At a Glance

If the servodrive fails, it may be necessary to swap it for an identical servodrive (reference). To do this, you are advised to save the adjustment parameters to a data table using the TE_UPLOADDRIVEPARAMETER block.

The TE_DOWNLOADDRIVEPARAM block then allows you to restore the saved data to a new servodrive.

Data Backup

The table below describes the procedure used to back up the servodrive’s data using the TE_UPLOADDRIVEPARAMETER block:

Step	Action
1	Disable the Enable parameter, which belongs to the MC_POWER block. Result: the servodrive switches to Disable mode.
2	Enable the input parameter Execute. Result: the servodrive switches to Downloading mode. The data table assigned to the output parameter PARAMETERSET is filled in. Note: Please back up data to a .DAT file using PLC → Transfer PLC data to the file if the PLC has no memory card.

Restoring Data

The table below describes the procedure used to restore the servodrive’s data using the TE_DOWNLOADDRIVEPARAM block:

Step	Action
1	Disable the Enable parameter, which belongs to the MC_POWER block. Result: the servodrive switches to Disable mode.
2	Change the servodrive. The new servodrive must have the same references as the faulty servodrive. Note: make sure you take all the necessary precautions when changing the servodrive.
3	Configure the new servodrive with the basic parameters (CANopen address, speed) or using the keypad on the front panel.
4	Enable the block’s input parameter Execute. Result: the servodrive switches to Downloading mode. The data table assigned to the input parameter PARAMETERSET loads the input PARAMETERLIST which corresponds to the servodrive parameter.
