We specialize in the following series:

• MR-J2S-xxA series, e.g., MR-J2S-70A
• MR-J2S-xxB series, e.g., MR-J2S-70B
• MR-J2S-xxCL series, e.g., MR-J2S-40CL
• MR-J2S-xxCP series, e.g., MR-J2S-40CP
• MR-J2S-xxD series, e.g., MR-J2S-200D-S016T005

Our repair process is preventive and includes a series of steps that ensure high repair quality.

The repair process for drive modules includes the following steps

• Preventive overhaul - replacement of all necessary defective and worn parts.
• Intensive cleaning.
• Comprehensive final and load tests on our test stands.
• Parameter matching or restoration.
• Filling out documentation and checklists.

For Mitsubishi drive modules, we replace

• Electrolytic capacitors
• Large buffer capacitors
• Relays
• Current measuring modules
• Optocouplers

Additionally, we replace certain parts that have proven to be frequently failing over multiple repairs and are therefore statistically selected for replacement.

To counteract shortages and discontinuations, we have processoriented software solutions that monitor our inventory. We order some parts in advance, and for series repairs, we even secure sufficient spare parts for a year to always have a large stock available.

The test is conducted at a test stand that simulates the processes like in a real machining plant.

During the test, the following are checked:

• BUS control
• POT/NOT
• Encoder connection
• Alarm conditions
• Speed
• Current and voltage consumption
• Temperature
• Parameters
