Kinco FD5P AC series servo driver
Chapter 10 Communication
10.1 RS232 communication
10.1.1 RS232 hardware interface
The mini-usb port under the panel cover of the FD5 series servo drive is the 232 debugging port, which can be connected to the
Kinco servo+ to directly control the work of the servo drive.
10.1.2 RS232 communication cable
The MINIUSB5p to DB9 configuration cable is the adapter cable between the drive and the computer. One end is connected
to the RS232 (DB9 pin header interface) of the computer, and the other end is connected to the Mini-usb interface of the drive. If
your computer does not have an RS232 DB9 interface, you need to use a USB-to-serial cable to connect.

10.1.3 RS232 transport protocol
FD5 series drives RS-232C communication strictly follows the master-slave protocol, Kinco servo+ can send any data to drive.
The drive sets the address to calculate these data and respond with a return value. The default communication parameters of FD5P
series servo are as follows:
Baud rate = 38400 bps
Data bit = 8
Stop bit = 1
No verificaiton
The communication ID can be set through the device station number d5.01, and the baud rate can be set through d5.02. After
setting, the baud rate must be saved by setting d5.00. The changed baud rate and ID will be restarted in the drive. effective later.
Note
When the host computer is connected through a baud rate of 115200, due to the high frequency of
transmission signals, there are certain requirements for the communication environment. If there is
a disconnection or frame loss, it is recommended to reduce the communication baud rate to
connect to the host computer software.
The transport protocol used by RS232 uses a fixed ten-byte packet format:
CHKS = -SUM(byte0……byte8)
，
CHKS are the last two digits of the calculation result
