Replacing Batteries In Indramat Motors

Replacing batteries in Indramat motors

Indramat components are so low maintenance that it’s easy to forget that you have to maintain them at all. When your machinery needs constant maintenance and repairs, checking to make sure your machinery works properly is always fresh in your mind. However, since Indramat servo drives, servo motors, and servo controls rarely fail, a decade can pass before you even consider the state of your machinery. One of the easiest things to overlook is the fact that you have to replace the battery for your Indramat motor.

Wait… there’s a battery?

Maybe you had no idea that your electric servo motor even uses a battery. Some Indramat servos, such as MKD motors, store information in motor feedback electronics. These electronics are backed by batteries to prevent information loss. The batteries in these servos typically last about 10 years.

Fortunately, your battery won’t just stop working without warning. If the battery for your Indramat servo motor falls below 2.8 volts, your controller generates an error code.

Once you see the F248 Low Battery Voltage error message, you need to replace your battery as soon as possible.

The absolute encoder function is only guaranteed for a couple of weeks after the F248 code appears. You must replace your battery within 14 days, if not sooner. If your motor loses absolute position information, your system will have difficulties controlling the motor and moving parts; this can lead to mechanical damage.

Replacing batteries in Indramat motors

While it’s easy to forget, replacing batteries in Indramat motors isn’t all that difficult. All that you need is a size 10 Torx screwdriver, a wrench, torque keys, and a new Indramat battery.

When replacing the battery, make sure that the power is switched off. Do not turn the power back on while you are replacing the battery. However, you should leave the control voltage on. If the battery is removed while the control voltage is switched off, you will have to re-establish the absolute dimension.

Here’s how to replace your battery

  • Remove all Torx screws
  • Pull out lid the of the resolver feedback RSF
  • Pull out the battery connector
  • Loosen the clamping device, and remove the battery
  • Insert the new battery and reattach the clamping device (It’s important that you do not pinch or otherwise damage the battery cable)
  • Insert the battery connector
  • Close the resolver lid and tighten all screws

It’s that simple. However, if you have difficulties replacing your Indramat battery, or if you have any other Indramat maintenance of repair needs, do not hesitate to give us a call!
