Setting the Measuring Wheel Encoder Parameters
Note: Difference monitoring can be activated when a measuring
wheel is used. This occurs using Parameter A117, Encoder
difference monitoring.
The following parameters are set for the measuring wheel encoder:
• C007, Feed rate constant 2
• C005, Feedback 2: type
• C006, Feedback 2: resolution
Diagnostic Messages
The following error messages can be generated in conjunction with the
measuring wheel mode command:
• D801 Measuring wheel mode not possible
Systemvariable
V107 "Slip in Measuring Wheel Mode [%]".
8.3 Homing
The position feedback value of the measuring system to be referenced
forms a coordinate system referencing the machine axis. If absolute
encoders are not used, this coordinate system does not correspond to the
machine coordinate system after the drive has been initialized.
Therefore, homing is used to:
• establish agreement between the drive measuring system and the
machine coordinate system in incremental measuring systems
• move to the reference point in absolute measuring systems.
Homing means that the drive independently generates the position
command values for initiating the necessary drive motions in accordance
with the homing velocity and acceleration settings.
Note: It is possible to perform this function for either the motor
encoder or the optional encoder.
