6.UNEXPECTED DISTURBANCE TORQUE DETECTION FUNCTIONHANDLING B-65395EN/01
- 182 -
No
093 Estimated load torque: torque offset compensation
[Size] 2-byte
[Unit of data] Torque command unit
[Valid data range] -7282 to 7282 (7282 is the maximum current value of the amplifier)
The setting is added to an estimated load torque, thereby eliminating an
effect of stationary torque including gravity.
No
094 Estimated load torque: dynamic friction compensation coefficient
[Size] 2-byte
[Unit of data] Torque command unit
[Valid data range] 0 to 7282 (7282 is the maximum current value of the amplifier)
[Setting value] An estimated load torque at 1000 min
-1
is measured and set.
The compensation proportional to the speed is added to the estimated
load torque, thereby eliminating an effect of dynamic friction.
No
095 Unexpected disturbance torque detection: retract distance
[Size] 2-byte
[Unit of data] Detection unit
[Valid data range] 0 to 65535
[Setting value] Set approximately 3 mm.
NOTE
Even if this parameter is set, if the movement is at a
speed lower than the that described below,
retraction is not performed but the tool stops at the
position at which an abnormal load is detected.
Let the value of the retraction parameter to be A,
If the speed is equal to or less than A/8 x detection
unit x 1000 [mm/min]: Stop at the detection point
If the speed is equal to or greater than A/8 x
detection unit x 1000 [mm/min]: Stop after retraction
