Integral Operation @ Accel/
Decel
Sets ASR integral operation during acceleration and deceleration.
0 : No
1 : Yes
Note:
When A1-02 = 0 [Control Method Selection = V/f], set H6-01 = 3 [Terminal RP Pulse Train
Function = Speed Feedback (V/F Control)] to enable this parameter.

Carrier Frequency Selection Sets the carrier frequency for the transistors in the drive.
1 : 2.0 kHz
2 : 5.0 kHz (AOLV/PM: 4.0 kHz)
3 : 8.0 kHz (AOLV/PM: 6.0 kHz)
4 : 10.0 kHz (AOLV/PM: 8.0 kHz)
5 : 12.5 kHz (AOLV/PM: 10.0 kHz)
6 : 15.0 kHz (AOLV/PM: 12.0 kHz)
7 : Swing PWM4 (Audible Sound 1)
8 : Swing PWM4 (Audible Sound 2)
9 : Swing PWM4 (Audible Sound 3)
A : Swing PWM4 (Audible Sound 4)
B : Leakage Current Rejection PWM
F : User Defined (C6-03 to C6-05)
Note:
• The setting range changes when the A1-02 [Control Method Selection] value changes:
–5, 8 [OLV/PM, EZOLV]: You can set C6-02 = 1 to 6, B, and F.
–6 [AOLV/PM]: You can set C6-02 = 1 to 6.
• The carrier frequency for Swing PWM 1 is equivalent to 2.0 kHz. Swing PWM applies a
special PWM pattern to decrease the audible noise.

Carrier Frequency Upper
Limit
Sets the upper limit of the carrier frequency. Set C6-02 = F [Carrier Frequency Selection = User
Defined (C6-03 to C6-05)] to set this parameter.

Carrier Frequency Lower
Limit
Sets the lower limit of the carrier frequency. Set C6-02 = F [Carrier Frequency Selection = User
