ECODRIVE03-FL*-04VRS Functions 8-27
DOK-ECODR3-FL*-04VRS**-FK01-EN-P
The following functions can also be set in the LAL/LAR command:
Under the following conditions, synchronization can be immediately
initiated with a rising edge at the "Immediate Synchronization" input,
during processing of the LAL or LAR command:
1. During processing of the LAL/LAR command, as long as the starting
point has not yet been reached.
2. When synchronization inhibit is active.
With a rising edge at the "Inhibit Synchronization" input in Automatic
Mode, an inhibiting of the next synchronization is requested. This request
causes an inhibiting of the beginning of synchronization in the next LAL or
LAR command. In this case, the direction to proceed to the next
instruction does not occur in these commands. "Synchronization
Inhibit" can only be canceled using an "Immediate Synchronization" (or
by switching to Manual Mode).
This mode can be set in the program by selecting the virtual encoder as a
master in the CMM command. The parameters for the master are set in
the VMC command.
Using the LAR command, the system waits for an input signal. When a
rising edge is present, synchronization is started immediately or after an
offset measurement occurs for the master.
Synchronization begins when the offset measurement becomes smaller
than the acceleration distance.
The offset measurement must be at least 2 x the acceleration distance.
Otherwise, synchronization cannot occur because of acceleration values
that are too high, and the error message
"F- 02 30 – Offset Measurement too large" is issued.
The programmed length is subtracted from the master position counter
value using the LAL command. The program then proceeds to the next
instruction. As soon as the master reaches the start position
(synchronous position – 2 x acceleration distance), synchronization
begins and the program proceeds to the next instruction. The first LAL
command after activating the function sets the master position counter to
the negative value of the "Product Length."
Commands:
CSY: Activating and defining the home position
CMM: Selecting the master, the cam shape and this function.
CLG: Determine the acceleration distance.
LAL: Calculate new product length. Synchronization occurs, as
soon as the start position is reached.
LAR: When a rising edge occurs at the synchronization input, a
new product length is set.
Synchronization occurs as soon as the start position is
reached.
LAE: End synchronization.
VMC: Control of the virtual master. (Test Mode)
