3.2.2 Set baud rate:
The baud rate must be consistent throughout the network in order to establish
communication and allow configuration via the network.
Therefore, this setting is important in the inverter unit configuration.
!
Switching power on initializes the FR-E500KND to the communication speed of
125Kbps.
!
You can set the baudrate via the network using DeviceNet, Class 0x03 - Instance 1 -
Attribute 2. (Refer to page 158)
!
By changing the Pr. 346 and Pr. 348 values, you can set the baudrate manually
from the parameter unit. (Refer to page 125)
3.2.3 Set node address:
The node address assigned to the inverter on page 47 establishes the default node
address when the inverter is powered on. If the same node address is found in the
network configuration, you can change the setting via the network using DeviceNet,
Class 0x03 - Instance 1 - Attribute 1. (Refer to page 158)
3.2.4 DeviceNet I/O assembly:
Communication between a master device and a slave device on the network requires
that the DeviceNet Class 0x04 – "Assembly Object" in both devices be the same.
(1) Default I/O assembly:
When power is switched on, the FR-E500KND is set to Class 0x04 - Output Instance
21 and Class 0x04 - Input Instance 71 as set at the factory. Refer to page 159 for
further information on DeviceNet Class 0x04 and changing the desired Output and
Input Instances.
(2) Polling rate:
Determination of the proper polling rate of the DeviceNet master device is dependent
upon the characteristics of the entire network. To minimize a collision and maximize
system reliability, we recommend that you set the polling rate intervals to be at least
30ms. The user may, at their discretion, adjust this rate as network performance
allows.
