Panasonic AC drives in India: servo drivers, spares and repair support
This page covers Panasonic AC drives in India used to control servo motors: MINAS servo drivers, replacements for obsolete models and repair or upgrade support. Industrisol sources these drives for machine owners and OEMs in Mumbai and across India. Looking for inverters for induction motors instead? See our Panasonic VFD page.

AC servo drive or VFD: which Panasonic AC drive do you need?
"AC drive" is used for two products. A variable frequency drive (VFD or inverter) controls the speed of a standard induction motor on fans, pumps, conveyors and mixers, and it improves energy use on variable loads. A servo drive (Panasonic calls it a servo driver or amplifier) works in a closed loop with an encoder-equipped servo motor to control position, speed and torque precisely.
Most enquiries we receive for Panasonic AC drives in India are for servo drivers on packaging, printing, CNC and special-purpose machines. These drivers are matched to a specific motor family, so the motor model is just as important as the drive model when you request a replacement. For induction-motor inverters, go to Panasonic VFDs.
Panasonic AC servo drives and support we offer
Panasonic AC servo drive (200 V class)
Panasonic servo drivers for three-phase 220 V supply, sourced to match your existing servo motor. Send the driver and motor nameplates and we will confirm the correct model, firmware generation and cables.
| Input | Three phase, 220 V class |
|---|---|
| Matching | Selected to suit the connected Panasonic servo motor |
| Typical use | Replacement on running machines |
Panasonic MFDDTA390 servo driver (MINAS A4, 3 kW)
MFDDTA390 is a 3 kW, frame F servo driver from the Panasonic MINAS A4 series, still found on many older machines in India. Variants include MFDDTA390N, MFDDTA390P and MFDDTA390003. It is used with motors such as MDMA302P1G, MDMA302P1H and MSMA302P1G.
| Series | MINAS A4 |
|---|---|
| Output | 3 kW |
| Frame | F |
| Input supply | Single phase or 3-phase, 200 V |
| Matching motors | MDMA302P1G, MDMA302P1H, MSMA302P1G |
| Variants | MFDDTA390N, MFDDTA390P, MFDDTA390003 |
Panasonic servo motor and drive repair
When a servo motor or driver fails, repair can be quicker than sourcing a discontinued part. Typical faults include encoder errors, overcurrent trips, damaged power stages and worn bearings. Share the fault code and nameplate details, and we will advise whether repair, a like-for-like spare or an upgrade makes more sense.
| Motor type | AC servo motors and drivers |
|---|---|
| Common faults | Encoder, overcurrent, power stage, bearing |
| Options | Repair, spare replacement or upgrade |
Legacy and obsolete Panasonic servo repair
Older MINAS generations are no longer produced, but many machines still depend on them. We take enquiries for repair of legacy Panasonic servo motors and drives, including higher-power units above 10 kW, and can quote a newer-series replacement set if repair is not viable.
| Coverage | Legacy and obsolete Panasonic servo motors and drives |
|---|---|
| Power range (listed) | Up to and above 10 kW |
| Alternative | Upgrade to current MINAS series |
Integrated servo motor service
Integrated servo motors combine the motor, drive and often the controller in one housing. We take service and replacement enquiries for integrated units in the 1 to 5 kW range from several makes, including units on EtherNet/IP, PROFINET, Modbus TCP, EtherCAT, CANopen and RS-485 networks.
| Power | 1 to 5 kW |
|---|---|
| Motor type | AC and DC integrated servo |
| Networks | EtherNet/IP, PROFINET, PROFIBUS, Modbus TCP, CANopen, RS-232/RS-485 |
Repair, like-for-like spare or upgrade?
A quick guide for maintenance teams facing a failed Panasonic AC drive.
| Situation | Usually best option |
|---|---|
| Model still available, machine must restart fast | Like-for-like spare |
| Model obsolete, fault is repairable | Repair, keeping a spare plan in mind |
| Model obsolete, repeated failures | Upgrade to a current MINAS motor and driver set |
| Several axes of the same old generation | Plan a staged upgrade and hold one repaired unit as a spare |
What to send with your Panasonic AC drive enquiry
Not sure about some details? Send what you have — we will ask the right follow-up questions.
- Driver model code and serial label (photo)
- Connected motor model code
- Alarm or error code shown on the driver display
- Supply voltage and phase
- Whether you want a spare, a repair quote or an upgrade option
- Machine location in India
Is a Panasonic servo driver the same as a VFD?
No. A VFD varies the frequency to control the speed of a standard induction motor, usually without position feedback. A servo driver runs a permanent-magnet servo motor in closed loop using its encoder, controlling position, speed and torque. They are not interchangeable, and each needs the correct motor type to work.
Can I replace a MINAS A4 driver such as MFDDTA390 with a newer model?
Yes, but usually as a set. Newer MINAS drivers use different encoder protocols, so the A4 motor normally has to be replaced along with the driver and cables. The control wiring and parameters also need to be adapted. If you only need the machine running quickly, a like-for-like A4 spare or a repair may be the faster route.
What information helps diagnose a failed Panasonic servo drive?
The alarm code on the driver display is the most useful detail, followed by when the fault occurs (power-up, during motion or at stop), the driver and motor model codes, and any recent changes such as new cables or a motor swap. Photos of the nameplates and the wiring help us give a more accurate repair or replacement quote.
Do you support servo brands other than Panasonic?
Our enquiries cover several makes, and integrated servo units from various manufacturers can be assessed case by case. Send the make, model and fault description. For Yaskawa drives specifically, see our Yaskawa AC drives page; for general servo brands, see the servo motor brands page.
Should I back up drive parameters before replacement?
Yes. Panasonic drivers store gain, filter and I/O settings that took time to tune. Use the PANATERM software or the front panel to save the parameters before removing a working unit, or note them down. If the old drive is dead, the machine builder may hold a backup, which saves commissioning time on the replacement.
Panasonic AC drive down or obsolete?
Send the driver and motor model codes and the alarm code for spares, repair or upgrade options.
