Regenerative Power Ride-Through Control Level; Braking Answer Waiting Time; Analog Input Wire Breakage Detection Level - Toshiba TOSVERT VF-AS1 Instruction Manual

Note: For , 100% corresponds to a voltage of 500V (for 500V class), 575V (for 575V class)
or 690V(for 690V 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% value 500V ( if  is set in)

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 ().

6.33.18 VI/II analog input wire breakage detection level
 : VI/II analog input wire breakage detection level
• Function
The inverter will trip if the VI/II value remains below the specified value for 0.3 seconds or moreThe
message "" is displayed.
=: Disabled ·········· The detection function is disabled.
=~ ·············· The inverter will trip if the VI/II value remains below the specified value for 0.3
