5.7.3 Start/Stop via Communication
The controller can start/stop the AC drive via various communications. When using communication functions,
the relative parameters F0-02 and F0-28 are needed to be set according to different communication types,
refer to the following table. In addition, an optional communication extension card is needed. For information
about optional communication cards, refer to Appendix A Expansion Optional Cards.

If the DC injection braking time is set to 0, the drive will start from the setting start-up frequency (F6-03). If the
DC injection braking time is not set to 0, the drive will start DC braking rstly and then start from the setting
start-up frequency (F6-03). This DC injection braking function is applicable to small-inertia loads which is easy
to slip during startup stage.
It is applicable to most small-inertia loads, the frequency curve is shown in the following gure. The DC injec-
tion braking function is applicable to drive load such as elevator and crane. Start frequency is applicable to
drive equipment which requires startup torque, such as cement mixer.
