• 2: Communication control
The most common configuration is when the host computer is used to control running
of the AC drive by means of communication, such as the RS485, PROFIBUS-DP,
CANlink, and CANopen. The I5300 interacts with the user programmable card also by
means of communication.
Install a matching communication card in the multifunction extension port, and set P0-
02 to 2. Then, you can start or stop the AC drive in communication mode. The following
figure shows the setting method.

When PD-04 is set to a non-zero number, the function of automatic AC drive stop upon
communication timeout is enabled. This prevents uncontrollable AC drive running due
to faults of the communication cable or the host computer.
The communication port of the AC drive supports the Modbus-RTU protocol, and the
communication is implemented only when the host computer supports the Modbus-
RTU master station protocol.
4.7.2 Start Mode
The I5300 supports three start modes, namely, direct start, rotational speed tracking
restart, and pre-excited start (asynchronous motor), set in P6-00.
•
P6-00 = 0 (direct start)
It is applicable to small-inertia load. The frequency curve in this mode is shown in the
following figure.
DC braking before the start is applicable to drive of load such as elevator and crane.
Startup frequency is applicable to drive with burst start under start torque, such as
cement mixer.
