Indramat motion control is very good — we meet a lot of servos which have been in service for 30 years before they have a problem. But we also see cases in which Indramat components fail — or seem to fail — repeatedly.
Often the problem is “dirty” power. We’ve heard of cases in which poor wiring or poorly grounded setups were the culprit, and we’ve seen plenty of examples where the voltage was just wrong. Check the 24vdc power and the ripple.
Servos are designed to check on parameters all the time, and to respond, often by stopping, when conditions change. If the voltage is wrong, or the fluctuation is broad enough to make the voltage wrong some of the time, the servo will respond correctly.
That is, it’ll stop.
Before you decide that your machinery is broken, check the voltage.
Next, check the cable.
Now, if you’re confident that your Indramat components really are on the fritz, you need to give us a call. Indramat components are not designed to be opened up and twiddled with. What’s more, you cannot buy new parts. Indramat was bought by Rexroth, now Bosch Rexroth. Bosch Rexroth doesn’t sell parts to third party repair shops, nor to Indramat owners.
Because of this, some Indramat users treat their components as disposable. If they don’t seem to be working correctly, they toss them and buy a new (used) component on eBay. If the underlying cause is poor quality power, you can run through half a dozen components before you give up.
Instead, choose factory repair. Bosch Rexroth supports legacy Indramat components with factory repair, which gets your machinery back to you in like-new condition. We can facilitate the process for you with phone support, field support, and emergency replacement units which yours are being repaired.
