5.4 Details of Function Codes
5-198
H63 Low Limiter (Operation Selection) (See F15)
For the lower limiter (operation selection) setting, see the section describing the function code F15.
H64 Low Limiter (Lower Limiting Frequency)
H64 sets the lower limit of frequency to be applied when the current limiter, torque limiter, automatic
deceleration (anti-regenerative control), or overload prevention control is activated. Basically, there is no
need to modify the default setting.
- Data setting range: 0.0 to 60.0 (Hz)
H65, H66 Non-linear V/f3 (Frequency and Voltage) (See F04)
For setting of non-linear V/f pattern, details, see the description of function code F04.
H67 Auto Energy Saving Operation (Mode Selection) (See F37)
For setting of auto energy saving operation (mode select), see the description of function code F37.
H68 Slip Compensation 1 (Operating Conditions Selection) (See F42)
For the setting of slip compensation 1 (operation condition selection), see the section describing the function
code F42.
H69 Anti-regenerative Control (Operation Selection)
Related Function Code: H76 Torque Limiter (Brake) (Increasing Frequency Limiter)
H76 is set when enabling the anti-regeneration control. In the inverter not equipped with an anti-regeneration
function (PWM converter or braking unit), if the regenerative energy returned exceeds the inverter's braking
capability, an overvoltage trip occurs.
When anti-regeneration control is selected, the output frequency is controlled, anti-regeneration energy is
kept low, and overvoltage trip is avoided.
