Overvoltage Limit Operation; Undervoltage Trip; Regenerative Power Ride-Through Control Level; Braking Answer Waiting Time - Toshiba Tosvert VF-AS1 Instruction Manual

6.33.14 Overvoltage limit operation

 : Overvoltage limit operation level
 For more details, refer to Section 6.14.2.

6.33.15 Undervoltage 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

time
Note: For , 100% corresponds to a voltage of 200V (for 200V class) or 400V (for 400V class)

6.33.16 Regenerative power ride-through control level

 : 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.)
Title
 Regenerative power ride-through control level
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)

6.33.17 Braking 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 ().
