Direct current braking(DB)

A dc voltage can be applied to the motor windings in order to lock

the motor shaft and avoid overun at low speeds.

There are two methods of activating the dc braking,

Outside which is through the intelligent input terminals and Inside

which is automatically started at a specific frequency.

Inside DC braking : valid

DC braking frequency

A052

0.00-60.00

Unit : Hz
When the output reaches the set frequency and
Inside DC braking is valid, DC braking is started.

DC braking late time

A053

0.0-5.0

Unit : second
After DC braking time is reached, or DB terminal
is ON, the late time is a delay before DC braking
is started.

0.0-60.0

Unit : second
The DC braking is stopped after this time delay
has elapsed. The time is tarted when the late
time has elapsed.

It is valid for inside DC braking.
When operating command is ON, DC current is
started.

(1) DC braking carrier frequency

It is possible to alter the DC braking carrier frequency. However, if the DC braking carrier frequency is set

higher than 3kHz, the value of maximum braking power level is automatically reduced as follows.

Set DC braking carrier frequency with A059.
