Flexible synchronization control
Parameter setting
The flexible synchronization control parameters are listed below:
(1) Denominators determining gear ratios (parameter Nos. 5681, 5683,
5685, and 5687)
(2) Numerators determining gear ratios (parameter Nos. 5680, 5682, 5684,
and 5686)
(3) Indexes to gear ratio denominators (parameter Nos. 5690, 5691, 5692,
and 5693)
(4) Master axis numbers (parameter Nos. 5660, 5662, 5664, and 5666)
(5) Slave axis numbers (parameter Nos. 5661, 5663, 5665, and 5667)
(6) M code numbers for turning synchronization mode ON (parameter Nos.
5670, 5672, 5674, and 5676)
(7) M code numbers for turning synchronization mode OFF (parameter
Nos. 5671, 5673, 5675, and 5677)
(8) Update of the machine coordinates (parameter Nos. 5668#0-#3)
Starting synchronization
Flexible synchronization control is started by setting flexible
synchronization control mode select signals (MTA, MTB, MTC, or MTD
(G197.0, G197.1, G197.2, or G197.3)) to 1. However, setting MTA, MTB,
MTC, or MTD to 1 during an automatic operation requires using an M code
specified in a parameter (No. 5670, 5672, 5674, or 5676). Up to three of
these M codes can be specified in one block by enabling the
one-block-to-multiple-M-code command (setting bit 7 of parameter No.
3404 to 1).
When MTA, MTB, MTC, or MTD is accepted, the flexible synchronization
control mode signal switching accepted signal (MFSYNA, MFSYNB,
MFSYNC, or MFSYND (F197.0, F197.1, F197.2, or F197.3)) is set to 1.
Canceling synchronization
Flexible synchronization control is canceled by resetting flexible
synchronization control mode select signals (MTA, MTB, MTC, or MTD
(G197.0, G197.1, G197.2, or G197.3)) to 0.
When MTA, MTB, MTC, or MTD is accepted, the flexible synchronization
control mode signal switching accepted signal (MFSYNA, MFSYNB,
MFSYNC, or MFSYND (F197.0, F197.1, F197.2, or F197.3)) is reset to 0.
