15854 Gap control gain at approaching
[Data type] Word axis
[Unit of data] sec
-1
[Valid data range] 0 to 32767
Specify the gap control gain during approaching gap control axis.
PRM No.15853 is used in case that this parameter is not set.
15855 Acceleration limit at approaching
[Data type] Word axis
[Unit of data] 0.1m/min (?)
[Valid data range] 0 to 32767
Specify the limit of acceleration for gap control speed.
The servo over-current alarm may occur at gap control start. So, to prevent the alarm, the
acceleration can be limited.
15856 Deflection at starting acceleration limitation
[Data type] Word axis
[Unit of data] 0.001mm
[Valid data range] 0 to 32767
The gap control acceleration is limited when the absolute value of the deflection is larger than
this set value at approaching.
15857 Upper limit on speed for the approaching side (Gap control B)
[Data type] Word axis
[Unit of data] mm/min
[Valid data range] 0 to 65535
Specify upper limit on speed for the approaching side.
15858 Upper limit on speed for the retraction side (Gap control B)
[Data type] Word axis
[Unit of data] mm/min
[Valid data range] 0 to 65535
Specify upper limit on speed for the withdrawing side.
Note
Please use this function in case of using a linear motor for gap control axis.
