* 1. Speed agreement conditions: The frequency reference and output frequency were entered
in the speed agree detection width set in L4−02.
* 2. Speed agreement conditions: The frequency reference and the (actual) motor speed based
on the PG feedback value were entered in the speed agree detevtion width set in L4−02.
F1-10 and F1-11 Settings
D
Constant F1-10 sets the PG speed deviation detection level as a percentage of the maximum output
frequency. Constant F1-11 sets the length of time in seconds that the difference between the motor
speed and reference speed must exceed the PG speed deviation detection level in order to detect a PG
speed deviation (DEV).

6.4.2 Setting the Zero-speed Operation Constants

With flux vector control, operation is possible even when the frequency reference is zero (below the
D
minimum output frequency).
Set the operation methods for the minimum output frequency.
