Solution

1.      Ensure the AX5803 TwinSAFE card is removed from the old drive and fitted to the new drive. The new drive will come with a TwinSAFE override card already fitted. It is important to keep the same TwinSAFE card during the switch over and not to replce it with a new one, as the TwinSAFE program is coded to the Axis <-> TwinSafe card combination. If the card is swapped, changes will be necessary to the Safety PLC program.

2.      In System manager, scan for devices to ensure the system configuration is the same. If not this needs to be sorted out before you can continue.

3.      In Drive Manager, check the drive has the correct motor fitted (this data, and all the rest should be downloaded to the drive on startup)

4.      In setup mode, check the associated axis moves in the correct direction. Change motor direction in axes.mul if necessary (inform GG if this happens – it shouldn’t!)

5.      In setup mode check the datum direction (Ensure step 4 OK first!). Change datum direction in System Manager Axis->Enc->Parameter Tab. Homing Invert. (inform GG if this happens – it shouldn’t!)

6.      Initialise machine. en none 0
