Item Heavy Duty Rating (HD) Normal Duty Rating (ND)
Application
A high overload tolerance is necessary during start up, acceleration,
deceleration, and equivalent conditions.
• Extruder
•
Conveyor
• Cranes and hoists
• Constant torque or high overload capacity are necessary.
Overload tolerance is not necessary.
• Fan
• Pump
• Blower
Overload Tolerance 150% - 60 seconds 110% - 60 seconds
Stall Prevent Level during Accel 150% 120%
Stall Prevent Level during Run 150% 120%
Carrier Frequency 2 kHz 2 kHz Swing-PWM
Note:
•
Set the stall prevention level during acceleration with L3-02 and the stall prevention level during run with L3-06 .
• Changing C6-01 also changes the maximum capacity of applicable drive motors. The drive automatically changes the setting values
E2-xx and E4-xx to applicable values. The drive also automatically changes these parameters that depend on motor output:
–
b8-04 [Energy Saving Coefficient Value]
– L2-03 [Minimum Baseblock Time]
– L3-24 [Motor Accel Time @ Rated Torque]
–
n5-02 [Motor Inertia Acceleration Time]

(0224)
Carrier Frequency Selection
Sets the carrier frequency for the transistors in the drive.
Determined by A1-02, C6-
01, and o2-04
(Determined by A1-02)
Changes to the switching frequency will decrease audible noise and decrease leakage current.
Note:
Increasing the carrier frequency to more than the default setting will automatically decrease the drive current rating.
1 : 2.0 kHz
2 : 5.0 kHz (4.0 kHz for AOLV/PM)
3 : 8.0 kHz
4 : 10.0 kHz
5 : 12.5 kHz
6 : 15.0 kHz
7 : Swing PWM1 (Audible Sound 1)
8 : Swing PWM2 (Audible Sound 2)
9 : Swing PWM3 (Audible Sound 3)
A : Swing PWM4 (Audible Sound 4)
B : Leakage Current Rejection PWM
Set this when the wiring distance between the drive and motor is long and there is a fault in the current monitor or
the drive detects and alarm because of the effect of a leakage current.
The carrier frequency is equivalent to 2.0 kHz.
F : User Defined (C6-03 to C6-05)
Use C6-03 to C6-05 to set detailed setting values.
Note:
•
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.
• The setting range changes when the A1-02 [Control Method Selection] value changes:
–
5, 8 [OLV/PM, EZOLV] : You cannot set to 7 to A .
– 6 [AOLV/PM] : You cannot set to 7 to A or F .
