JAROL Assumes the promotion of energy-saving technology as its own task!

F 1.03 and F 1.04. It is suitable for the motor which

have small inertia load and may reverse rotation

when start.

2: Speed tracking and start: Inverter detects the

rotation speed and direction of motor, then start

running to its reference frequency based on

current speed. This can realize smooth start of

rotating motor with big inertia load when

instantaneous power off.

Set proper starting frequency can increase the

starting torque. T he inverter runs from the starting

frequency and after the keeping time of the

starting frequency, the inverter will accelerate to

the aimed frequency during the ACC time. If the

reference frequency is less than starting frequency,

the inverter will be at stand-by status. The

indicator of RUN/TUNE light s on, inverter has no

output. The starting frequency could be less than

the lower frequency limits. The starting frequency

take s no effect during FWD/REV switching

D uring the DC braking before F 1.03 , the

increased current is the percentage to the rated

current of the inverter.

DC braking is invalid when F 1.04 is set to be 0.

The bigger the DC braking current, the greater the

braking torques.
