Beware of Fake Devices – Why Repairs Often Trump New Purchases
Customers are increasingly reporting negative experiences with counterfeit electronic devices, especially with Omron’s R7D series Servopacks (R7D-AP04H and R7D-AP02H). Since the manufacturer discontinued these products, the market has been flooded with deceptively realistic fakes from China and unreliable dealers.
Practical Experience: When “Cheap” Becomes Expensive
One of our customers, who uses hundreds of these devices in his machines, learned the hard way about trusting seemingly cost-effective deals. After sourcing devices from China and European service providers claiming to be official partners of Omron or Yaskawa, he discovered that many delivered devices had been tampered with. Older versions (Version 11) were particularly affected, illegally relabeled as Version 22.
The consequences were severe:
- Parameters could not be correctly loaded.
- Frequent malfunctions and unplanned machine downtimes occurred.
- Operational safety and productivity significantly suffered, leading to substantial follow-up costs.
Risks of Cheap Repairs – Why Quality Matters
What seems like an affordable repair from unauthorized providers can quickly turn into a nasty surprise. These providers often lack the specific knowledge and test equipment necessary for proper restoration. Customers have reported devices that appeared repaired but quickly failed again or even caused irreversible machine damage.
