Overview of Gear Mode

2.12.3.1
This chapter describes Gear mode, including the different synchronizing types, master handling, and control/status signals. Gear mode is
selected with the parameter 5.4.2.16 Operation Mode.
In Gear mode, the drive is position-controlled. The target position is given by a master signal taking the gear ratio into account, thus
synchronizing the movement of the follower to the master and forming an electronic shaft.

Function
Executes a positioning command and controls when new references are used depending on the position-
ing type:
Absolute positioning
A pulse executes a positioning command and completes it with the references active at the point of exe-
cution. Any change to the references is ignored unless activated with a new pulse.
A permanent high signal executes a positioning command, and any changes to the references are taken
into account while running or after reaching the target.
Relative positioning
A pulse executes a positioning command and completes it with the references active at the point of exe-
cution. Any change to the references is ignored unless activated with a new pulse.
A permanent high signal executes a positioning command once triggered by the rising edge, and any
changes to the speed and acceleration references are taken into account while running. Any change to the
position reference is ignored unless activated with a new pulse.
Used as binary code to select between the 8 preset position references.
• Low signal = Absolute positioning
• High signal = Relative positioning
At edge-triggered start of Touch Probe positioning, the drive runs in Speed mode until the touch sensor is
detected and then switches to Positioning mode.
Changes to speed reference are accepted until the touch sensor has been detected. Relative positioning is
executed using the actual speed and position reference.
Function
Signals that a positioning command is active. The signal is reset when the target is reached.
Signals that a positioning command is completed, and the target is reached with the actual position
within the On Target Window. Stays active while the actual position is inside the On Target Window, or un-
til a new target is activated.
