3EBI 4010: external backup battery

Mounting

The multiturn functionality of the EBI 4010
is realized through a revolution counter. To
ensure that the absolute position information is available after a power failure, theEBI must be operated with an external
backup battery.

The scale drum of the rotary encoder is pressed onto the measured shaft’s centeringcollar and fastened. The stator is mounted via an external centering diameter. In eachcase, use screws with material bonding anti-rotation lock (see Mounting accessories).

To prevent damage to the encoder, ensure
correct polarity of the backup battery.
HEIDENHAIN recommends operating each
encoder with a separate battery.
If the application requires compliance withDIN EN 60086-4 or UL 1642, an appropriate protective circuit is required for protection from wiring errors.

Downstream electronics

Requirements on the motor side for a safe mechanical coupling:
Mating shaft / Mating stator① = Protective circuit
Backup battery connection

Battery current in μA A 3.6 V, 1200 mAh lithium thionyl chloride
battery is recommended for the backup
battery. The typical service life is over six
years under the appropriate conditions(two shifts of ten hours each in normal operation; a battery temperature of 25 °C;
typical self-discharging). To reach the typicalservice life, the main power supply (UP)must be connected to the encoder during
or immediately after connection of thebackup battery so that the encoder is fully
initialized after being completely withoutpower. Otherwise, the encoder will consume a significantly higher amount of battery current until main power is first supplied.

If the backup battery voltage falls below
certain thresholds, then the encoder will
issue the following warnings or error
messages transmitted via the EnDatinterface:• “Battery charge” warning≤ 2.8 V ±0.2 V in normal mode
• “M power failure” error message≤ 2.2 V ±0.2 V in battery-buffered mode(encoder must be referenced again)

Please note the information on screws from HEIDENHAIN in the Encoders for Servo
Drives brochure, under the heading Rotary encoders with functional safety in the chapter
General mechanical information.
Mounting aid
The mounting aid is used for plugging and unplugging the PCB connector. It prevents
damage to the wires and crimp contacts because the strain is applied only to theconnector. The wires must not be pulled.

Please note:
Compliance with EnDat
Specification 297403 and the EnDat
Application Notes 722024, Chapter 13,
Battery-buffered encoders, is required forcorrect control of the encoder.
