■ b8-05: Power Detection Filter Time (V/f)
The Energy Saving function continuously searches out the lowest output voltage in order to achieve minimum output
power. Parameter b8-05 determines how often the output power is measured in ms.
Reducing this setting will increase the response time. If the filter time is too short, the motor may become unstable with a
lighter load.
■
b8-06: Search Operation Voltage Limit (V/f)
Sets the voltage limit for the optimal output voltage detection of Speed Search as a percentage of the maximum output
voltage. During the search operation, the drive will keep the output voltage above this level to prevent motor stalling.
Note: If set too low, the motor may stall with a sudden increase to the load. Disabled when b8-06 = 0. Setting this value to 0 does not
disable Energy Saving.
No. Name Setting Range Default
b8-05 Power Detection Filter Time 0 to 2000 ms 20 ms
No. Name Setting Range Default
b8-06 Search Operation Voltage Limit 0 to 100% 0%
