Common faults
What usually fails on a unit like the SGDR-SDA710A01B
Servo drives combine a power stage with fast feedback and position control, so a fault can sit in the power section, the encoder interface or the control board. Repair at component level keeps the axis tuning and the machine's configuration intact.
Overcurrent and power-stage faults
Failed output transistors or a damaged motor cable cause overcurrent or short-circuit alarms, often on one axis only.
Encoder and feedback alarms
Feedback alarms can come from the motor encoder, the cable or the drive's encoder interface. The drive is tested with a known-good motor and cable to tell them apart.
DC bus and regeneration faults
Overvoltage on deceleration, failed regen resistors and ageing bus capacitors are common on presses and fast-cycling axes.
Control and communication faults
Loss of the fieldbus or motion network, corrupted firmware or a failed control board leaves the axis disabled while the power stage is fine.
Overheating
Clogged cabinet filters and failed fans cause thermal alarms that come and go with load and ambient temperature.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Record the alarm number on every axis, not only the one that stopped.
- Check cabinet fans and filters.
- Look for damaged or pinched motor and encoder cables along the drag chain.
Leave to a specialist
- Swapping drives between axes without checking parameters and motor matching.
- Opening the drive or replacing power devices.
- Re-tuning the axis after a repair.
Getting it fixed
How to get the SGDR-SDA710A01B repaired
What to send with it
- The drive, with its option cards fitted as they were in the machine.
- The alarm number and when it appears (power-up, enable, motion, stop).
- The motor model it drives, from the motor nameplate.
Onsite or ship-in
Technicians work onsite from our Hyderabad base and travel to plants across India; anything that can be removed can also be sent to MachineryFix from anywhere in the country.
Warranty. Repairs carry a warranty of 30 days to 6 months, depending on the item and the repair; the exact term is confirmed before work starts.
FAQ
SGDR-SDA710A01B repair questions
Does the Yaskawa SGDR-SDA710A01B need its motor sent with it?+
Not usually. The drive can be tested on a bench motor. Send the motor too if the alarm points at feedback or the motor itself, or if the fault follows the motor when drives are swapped.
Will the axis need re-tuning after the repair?+
If the drive's parameters and firmware are preserved, it normally goes back into the machine with the same settings. A parameter backup sent with the drive avoids surprises.
Does the Yaskawa SGDR-SDA710A01B have to be sent in, or can an engineer come to the plant?+
Either. An engineer can diagnose it in place and repair it there or take it away, or the unit can be sent to MachineryFix from anywhere in India. The diagnosis and repair cost are confirmed before any work starts.
Is MachineryFix connected to Yaskawa?+
No. Yaskawa and the model name are used only to identify the equipment. MachineryFix is an independent repair service and is not affiliated with or endorsed by Yaskawa.
