7-76 Operating Modes MPH-02, MPB-02, MPD-02
DOK-INDRV*-MP*-02VRS**-FK01-EN-P
Note: For sequential block chains this is the last active block of the
sequential block chain. For single blocks (no sequential
block processing) the contents of parameters P-0-4052
and P-0-4053 are always equal!
P-0-4057, Positioning block, input linked blocks
contains an image of the digital sequential block inputs (switch cam
inputs)
Diagnostic Messages
In positioning block mode the following diagnostic messages can be
generated:
E0248 Interpolation acceleration = 0
E0249 Positioning velocity >= S-0-0091
E0253 Target position out of travel range
E0254 Not homed
E2055 Feedrate override S-0-0108 = 0
E2058 Selected process block is not programmed.
E2064 Target position out of num. range
F2028 Excessive deviation
7.8 Synchronization Modes
Basic Functions of the Synchronization Modes
Brief Description
The synchronization modes allow the drive to run synchronously with
regard to a real or virtual master axis. The synchronization modes are
divided into the following two groups:
velocity synchronization with real/virtual master axis
synchronous position control modes
phase synchronization with real/virtual master axis
electronic cam shaft with real/virtual master axis
The figure below illustrates how the synchronization modes are integrated
in the control loop structure.
