C80 Series Maintenance Manual 3 Maintenance of the Drive Unit

3.3.2 MDS-EJ/EJH Series

3.3.2.1 Replacing the Drive Unit

Arrangement of replacing parts Contact Mitsubishi branch or your dealer for an order or a replacement of the drive unit. Place an order for the same type of a drive unit as the one to be replaced. Replacement procedure Replace the drive unit with the following procedures. Procedures (1) Turn the breaker for the input power OFF. Make sure the CHARGE lamp of the power supply unit is turned OFF. (2) Disconnect all the connectors and the wires connected to the drive unit. (3) Remove the two (four) screws fixing the drive unit onto the control panel. Remove the drive unit from the control panel. (4) Make a same setting for the rotary switch and the dip switch of the new drive unit as those of the uninstalled drive unit. (5) Install a new drive unit by following the removal procedure in reverse. Restoration Data backup and restoration is not required before replacing drive units because drive units' data such as parameters are stored in the controller. However, carry out a backup of the whole system before replacement as a precautionary measure. The power for keeping the encoder's position data of an absolute position system is supplied from the battery connected to the drive unit. Keep the power ON once for 30 minutes or more if possible, and make sure to complete the replacement within 60 minutes after charging the encoder's capacitor.
