Application parameter group 10
PARAMETER DESCRIPTION 265
10-38(P.278) is the switch frequency between deceleration time during input power failure 1 and deceleration time
during input power failure 2; If 10-37(P.277) is not set, motor will still decelerates for the time set to 10-36(P.276).
10-39(P.279) is UV avoidance voltage gain when 10-33 set to 11 or 12; if 10-33(P.273)=1 or 2, 10-39(P.279) is
invalid.
under-voltage avoidance function(10-33(P.273)=”11”,”12”):
When setting 10-33(P.273)=”11” or “12”, frequency is decreased to prevent an under-voltage from occurring
during deceleration at input power fail.
Frequency drop trend and responsiveness can be adjusted by 10-39(P.279). If the set value is larger, the
response to bus voltage changes will be better. However, if the load inertia is large, the regenerative energy will
also be large, so 10-39(P.279) should be set smaller at this time.
Note: 1.This function is only for V/F control mode.
2.This function won’t work when using DC bus power supply

VF complete separation
Parameter 10-40(P.700)~10-44(P.704) are valid only when 01-12(P.14)=14. VF complete separation is normally
used in induction heating, inverse power supply and torque motor control.
The voltage source for V/F complete separation is set in the same way as the frequency source, it can be set by
digital or external analog terminal or HDI terminal.
