Kinco FD5P AC series servo
The send PDO (TPDO) function of FD5P series servo drives supports synchronous and asynchronous
transmission modes, and the corresponding transmission type can be selected according to the
transmission mode. For the receiving PDO (RPDO), in the non-interpolation mode when the driver
node is turned on, as long as the RPDO message sent from the bus is detected, the object data will
be received in real time, which has nothing to do with the transmission type setting
.
In interpolation
mode, the drive will receive data first after detecting the RPDO signal, but will update the object data
only at a specific point in time. For detailed interpolation mode control see chapter
10.3.4 Description.PDO
prohibition time
A PDO can specify a prohibition time, that is to define the minimum interval between
two consecutive PDO transmissions, to avoid the problem that the data volume of
high-priority information will always occupy the bus and make other data with lower
priority unable to compete for the bus. The disable time is defined by a 16-bit
unsigned integer, the unit is 100ms.
PDO
Event time
The cycle time for the drive to send the PDO message to the controller in the asynchronous
transfer mode, in ms. Note that when using event time, the inhibit time should be set to 0.
Description of protection method/supervision type
Supervision type refers to which inspection method the master station chooses to check the
slave station during the running process, judge whether the slave station is faulty or not by
these two methods, and make corresponding treatment according to these faults.
1、Master heartbeat message
The slave station periodically uploads messages to the master station with the "supervision
time". If the master station has not received the next heartbeat message from the slave
station after the "heartbeat client time", the master station judges that the communication is
wrong and generates an alarm!

、Slave heartbeat message
The master station periodically sends messages to the slave station according to the
"supervision time". If the slave station has not received the next heartbeat message from the
master station after the "heartbeat producer time", the slave station will determine that there
is a communication error! When the communication interrupted mode（
0x600700
）is
1
，
When the CAN communication fails, the drive will alarm and stop.
