Configuring the Kinetix 3 Drive Chapter 5

Understanding the

Encoders Window

The Properties window for Encoders looks like this.

Use the Encoders window to:

• configure the motor encoder,

• execute a command that will reset an absolute encoder position to zero.

This window has these parameters and direct commands.

Parameter Description

Encoder Output Forward

Direction

The order of the A and B signals for the encoder output:

• A Leads B

• B Leads A

Output Ratio The ratio of encoder output counts to motor encoder counts

received from the motor.

The range is of 1…65,535.

Encoder Backup Battery The encoder back-up battery, if installed in the drive, powers an

SA35 type encoder that maintains an absolute multi-turn position.

Without a battery, an SA35 type encoder operates as a single turn

absolute encoder. You must configure this setting to let the drive

know if the battery is not present.

Select:

• Installed

• Not Installed

Note: This parameter is visible only if the motor has an SA35 type

encoder.

Incremental Feedback Loss In electrically noisy conditions, or with long feedback cables, the

drive may experience an incremental encoder cable open fault,

although the cable is OK. Under these conditions, this parameter

can be used to avoid nuisance faults.

ATTENTION: If the incremental

encoder feedback is lost and this fault

is ignored, the drive may cause abrupt

or extreme motion.

Select:

• Monitored: to monitor for incremental encoder feedback loss,

and fault the drive if it is detected.

• Ignored: to not check for incremental encoder feedback loss.
