6.25.12 Over-voltage stall protection level
 Over-voltage stall protection level(high response)
 Over-voltage stall protection level
Refer to 6.13.5 for details.
6.25.13 Under-voltage trip
 Under-voltage trip mode
 Under-voltage detection time
 Disabled Inverter stops, but does not trip.(FL is not active)
 Enabled The inverter trips if an under-voltage passes for the time
set with  or over. (FL is active)

6.25.15 System-supporting sequence (B-timer)
 System-supporting sequence (B-timer)
Title Function Adjustment range Default setting
 System-supporting sequence (B-timer) : Invalid
  [s] 
Function
This parameter is to select the action when detecting an under-voltage. (Invalid, while the
inverter stops.) If  is set at (Enabled), it is necessary to set, with , the time
elapsed before the inverter trips after the detection of an under-voltage .
Function
This parameter is used to set the operation level of the regenerative power
ride-through control and the deceleration stop. (Refer to 6.13.2)
Function
This parameter is used to set the waiting time for answer from system(Input terminal function
setting: System-supporting sequence (BA:,) ). After start of operation, if no answer
is received in set time(), the inverter trips().
