When temporarily incorrect encoder signals are detected the drive

generates the warning

• E2074 Encoder 1: encoder signals disturbed

- or -

• E2075 Encoder 2: encoder signals disturbed

The warning remains active until the drive is switched off or switched to

communication phase P2!

When incorrect encoder signals are detected the drive generates the

error message

• F8022 Enc. 1: enc. signals incorr. (can be cleared in ph. 2)

- or -

• F2042 Encoder 2: encoder signals incorrect

When the voltage of the battery of the encoder data memory has fallen

below the determined limit value, the drive generates the following error

message:

• F2048 Low battery voltage.

Absolute Measuring Systems

Brief Description

Depending on their design and the mechanical arrangement at the axis,

position encoders can be evaluated by IndraDrive controllers as

• relative encoders (incremental encoders)

- or -

• absolute encoders (absolute value encoders)

if they have the required signal specification.

Rexroth position encoders and motor encoders of Rexroth housing

motors are available as

• single-turn encoders (absolute actual position values over one encoder

shaft revolution)

- or -

• multi-turn encoders (absolute actual position values over

4096 encoder shaft revolutions).

These encoders can be evaluated as absolute encoders if the travel

range of the axis can be represented within the absolute actual position

value range of the encoder:

• in the case of single-turn encoders within one encoder shaft revolution

• in the case of multi-turn encoders within 4096 encoder shaft

revolutions

As a standard, Rexroth housing motors are equipped with a position

measuring system. The individual motor series have different measuring

systems which allows offering cost-efficient motors depending on the

application.

The following measuring systems are used:

• HSF ("high-resolution servo feedback"), single- or multi-turn type

• resolver, single- or multi-turn type
