Refer to Pr.06-16 for more details of stall level in flux weakening region. The protection curve is
as follows:
When you enable the over-current stall prevention, the drive’s acceleration time is longer than the
setting.
When the over-current stall prevention occurs because the motor capacity is too small or operates
in the default, decrease the Pr.06-03 setting value.
If you encounter any problem with the acceleration time, refer to the following guides for
troubleshooting.
1. Increase the acceleration time to a proper value.
2. Set Pr.01-44 Auto Acceleration and Auto-Deceleration Setting to 1, 3 or 4 (auto-
acceleration).
