3 : Beyond 1:50
Adjust in the following situations.
•
The ratio between the motor inertia and machine inertia is more than 1:50
•
Parameter
n8-55 = 2
and the drive detects
STPo
because of an impact load or sudden acceleration/deceleration.

HFI Overlap Selection
Sets the function that detects motor speed with high frequency injection.
0
(0, 1)
Note:
•
When you set
n8-57 = 1
, doHigh Frequency Injection Auto-Tuning.
•
When there is high frequency injection, the motor will make an excitation sound.
•
When you use Zero Speed Control, set
E1-09 [Minimum Output Frequency] = 0.0
.
0 : Disabled
Use this setting with SPM motors. The speed control range is approximately 1:20.
When
n8-57 = 0
, you cannot set
E1-09 [Minimum Output Frequency]
≤ 1/20 of the value of
E1-06 [Base Frequency]
.
1 : Enabled
The speed control range changes to 1:100 to give sufficient speed detection at low speeds.
Note:
It is not available with an SPM motor.

Output Voltage Limit Level
Sets the output voltage limit to prevent saturation of the output voltage. Usually it is not necessary to
change this parameter.
200 V Class: 200.0 V, 400 V
Class: 400.0 V
(200 V Class: 0.0 to 240.0 V,
400 V Class: 0.0 to 480.0 V)
Set this parameter lower than the input power supply voltage.
Note:
•
When
A1-02 = 7, 8 [Control Method Selection = CLV/PM, EZOLV]
, this parameter is available in Expert Mode.
•
When
A1-02 = 8
, the default setting is
–
200 V Class: 230.0 V
–
400 V Class: 460.0 V
