F248 Low Battery Voltage
Cause:
The connected motor has an absolute encoder. The absolute position
information is stored in the motor feedback. This memory has a battery
powered backup for the electronic circuit. The battery is designed for a
operating life of 10 years. If the battery voltage drops below 2.8 V, this
message appears. The absolute encoder function is preserved for about
2 weeks.
Instructions for Exchanging Batteries
Have the following tools and accessories ready:
• Torx screwdriver,size 10
• Needle nose pliers, torque wrench
• New packaged battery (Part no.: 257101)
If the control voltage of the installed battery is turned off, the absolute
position is lost.
The absolute position must be re-established through the process of the
command Set Absolute Measurement.
