8317 Torque difference alarm detection timer (one master/slave axis pair under synchro-
nous control)
[Data type] Word
[Unit of data] ms
[Valid data range] 0 to 4000 (if 0 is specified, the system assumes 512 ms.)
This parameter specifies the time between the servo preparation
completed signal SA <F000#6> becoming 1 and the torque difference
alarm detection function starting to check for a torque difference alarm
condition. The specified value is rounded up to the nearest multiple of
16 ms.
(Example) If 100 is specified, 112 ms is assumed.
8323 Limit imposed on the positional deviation difference between the master and slave
axes (two master/slave axis pair under synchronous control)
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 0 to 32767
This parameter specifies a limit imposed on the positional deviation
difference between the compensation and slave axes. If the limit is
exceeded, a P/S alarm (No. 213) is issued. This parameter must be set for
the master axis. If 0 is specified, a positional deviation difference check
is not performed.
8325 Maximum compensation to be applied during synchronization matching (two mas-
ter/slave axis pair under synchronous control)
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 0 to 32767
This parameter specifies the maximum compensation to be applied
during synchronous compensation. If the compensation exceeds the set
value, a servo alarm (No. 410) is issued. This parameter must be set for
the master axis. For this setting to become effective, parameter SOFx (bit
7 of parameter No. 8303) must be set to 1.
8326 Reference counter difference between the master and slave axes (two master/
slave axis pair under synchronous control)
[Data type] Two–word axis
[Unit of data] Detection unit
[Valid data range] –99999999 to 99999999
This parameter is automatically set to the reference counter difference
(grid deviation) between the master and slave axes, when automatic grid
position setting is performed. This parameter setting, together with an
ordinary grid shift, is transferred to the servo section, when the user
subsequently switches the power off then back on. This parameter must
be set for the master axis.
