Note: If this mode is required all safety measures must be considered including warning
labels.
 When direct run on power up is disabled by 07-04=1and if the inverter is set to external run by
(00-02/00-03=1), if the run switch is ON as power is applied, the inverter will not auto start and
the display will flash with STP1. It will be necessary to turn OFF the run switch and then ON
again to start normally.

DC Injection Brake Start Frequency (Hz)
Range

0.10 ~ 10.00

Hz
 When DC Injection braking is active DC voltage is applied to the motor, increasing the braking
current and resulting in an increase in the strength of the magnetic field trying to lock the motor
shaft.
 To enable DC injection braking during a stop operation set the DC injection braking current (07-
07) and the DC injection braking time at stop (07-08) to a value greater than 0.
Notes:
- Increasing the DC braking time (07-08) can reduce the motor stop time
- Increasing the DC braking current (07-07) can reduce the motor stop time.
- During stop operation: If the DC braking start frequency < minimum output frequency
(01-08), DC braking is activated when the output frequency reaches the minimum output
frequency level.

Based on the 20% of maximum output voltage
【0~ 100】% (Sizes 3/4) Based on invertor rated current
 Sizes 1/2 models, please refer the formula below.
In V/F mode, the value is equal to 0~20% of max output voltage (01-01)
In SLV mode, the value is equal to 0~20% of max output voltage (02-04)
 Sizes 3/4 models, the value is the equal to 0~100% of inverter rated output current.

 07- 09 = 【0】: after receiving stop command, the motor will decelerate to stop according to
setting of 00-15, deceleration time 1.
 07- 09 = 【1】: after receiving stop command, the motor will free-run (Coast) to stop.
