6.33.14Overvoltage limit operation!

￿￿￿￿: Overvoltage limit operation level

￿For more details, refer to Section 6.14.2.

6.33.15Undervoltage trip!

￿￿￿￿: Undervoltage detection level

￿￿￿￿: Undervoltage trip selection

￿￿￿￿: Undervoltage (trip alarm) detection time

• Function

This parameter is used for selecting the control mode when an undervoltage is detected. (Invalid, while the inverter stops.) When selecting “tripping enabled,” you can also specify the time elapsed before the inverter trips.

￿￿￿￿=￿: (Disabled) ················ Inverter stops,but does not trip. (FL is not active.)

￿￿￿￿=￿: (Enabled) ················ The inverter trips ￿￿￿ if an undervoltage passes for the time set with ￿￿￿￿ or

over. (FL is activated.)

￿￿￿￿

: Regenerative power ride-through control level

 

• Function

This parameter is used to set the operation level of the regenerative power ride-through control and the deceleration stop. (Refer to Section 5.18.2.)

Note1: Set this parameter at a value of ￿￿￿￿+5% or more. Or the braking time of regenerative power ride-though control could be extremely shorter. This setting is not necessary if ￿￿￿￿ is set to ￿￿ (auto mode).

Note2: When power on or reset operation, the power supply voltage is detected. If the setting value of parameter

￿￿￿￿is too low, the setting value is automatically adjusted to stabilize the performance. Note3: For ￿￿￿￿, 100% corresponds to a voltage of 200V (for 200V class) or 400V (for 400V class)

6.33.17Braking answer waiting time!

￿￿￿￿

: Braking answer waiting time

• Function

This parameter is used to set the waiting time for answer from system (Input terminal function setting: System supporting sequence (BA: Braking answer ￿￿￿, ￿￿￿)). After start of operation, if no answer is received in set time (￿￿￿￿), the inverter trips (￿￿￿￿).
