- 323 -
2818 (FS15i)
Synchronous axes automatic compensation: Filter coefficient
2405 (FS16i)
[Valid data range] 32700 to 32767
[Typical setting] 0 (equivalent to a time constant of 1 second)
Set the time constant for reflecting the twist in position compensation.
As a larger coefficient is set, compensation to release the twist is
performed more slowly.

NOTE
1 This function reduces the difference in torque
between the master and slave axes by adding
compensation pulses to the slave axis. In the
steady state, position error equivalent to the
compensation amount is accumulated in the slave
axis.
2 This function cannot be used together with the dual
position feedback function.
3 Set parameters on the even-numbered axis side.
4 Be sure to assign the master and slave, which are
the synchronized axes, to the odd- and
even-numbered axes on the same DSP.
With the following servo software, a dead-band width can be set:
(Series 15i-B,16i-B,18i-B,21i-B,0i-B,0i Mate-B,Power Mate i)
Series 90B1/A(01) and subsequent editions
Set the following parameter for the odd-numbered axis side (the
master axis) only:
2817(FS15i)
Synchronous axes automatic compensation: Dead-band width
2404(FS16i)
[Unit of data] Percentage (%) with respect to rated current
[Valid data range] 0 to 800
If the difference in torque command between the master axis and slave
axis is within the dead-band width, the synchronous axes automatic
compensation value becomes 0.
