Chapter 16 Troubleshooting
Remedy
Review the positioning address.
• Correct the center point address (arc address)
• Correct the end address (positioning address)
Correct the circular interpolation error allowable limit value.
At operation start : • Set the current feed value within the
software stroke limit by the manual
control operation.
(Refer to Chapter 11)
• Correct the positioning address. (At
circular interpolation with sub points
designated, also check the arc address.)
New current value : Set the new current value within the
software stroke limit. (Refer to Section
9.2.19)
During operation : Correct the positioning address.
(For the positioning and arc addresses,
refer to
Da.6
At speed control mode/torque control mode/continuous
operation to torque control mode:
Review the operation so that the current
feed value does not exceed the software
stroke limit.
and in Section 5.3)
