F607 is used to set selection of stalling adjusting function.
Voltage control: when motor stops quickly or load changes suddenly, DC bus voltage will be
high. Voltage control function can adjust deceleration time and output frequency to avoid OE
trips.
When braking resistor or braking unit is used, do not use voltage control function
otherwise, the deceleration time will be changed.
Current control: when motor accelerates quickly or load changed suddenly, inverter may trip
into OC. Current control function can adjust accel/decel time or decrease output frequency to
control proper current value. It is only valid in VF control mode.
Note: (1) Voltage/current control is not suitable for lifting application.
(2) This function will change accel/decel time. Please use this function properly.
Initial value of stalling current adjusting is set by F608, when the present current is higher than
rated inverter current *F608, stalling current adjusting function is valid.
During the process of deceleration, stalling current function is invalid.
During the process of acceleration, if output current is higher than initial value of stalling
current adjusting and F607=1, then stalling adjusting function is valid. Inverter will not
accelerate until the output current is lower than initial value of stalling current adjusting.
In case of stalling during stable speed running, the frequency will drop. If the current returns to
normal during a stall condition the frequency will rise. Otherwise, the frequency will keep
dropping to the minimum frequency and the protection OL1 will occur after it lasts for the time
as set in F610.
Initial value of stalling voltage adjusting is set by F609, when the present voltage is higher than
rated voltage *F609, stalling voltage adjusting function is active.
Stalling voltage adjusting is valid during the process of deceleration, including the deceleration
process caused by stalling current.
Over-voltage means the DC bus voltage is too high, and it is usually caused during
deceleration when the DC bus voltage will increase because of energy feedback. When DC
bus voltage is higher than the value of stall voltage (F609) and F607=1, then stall adjustment
function is active. The inverter will temporarily stop decelerating and keep output frequency
constant, this stops energy being fed back into the inverter. Inverter will not decelerate until DC
bus voltage is lower than the value of stall voltage (F609).
Stalling protection judging time is set by F610. When inverter starts stalling adjusting function
and continues the period of time set by F610, inverter will stop running and OL1 protection
occurs.
