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
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.
