registers read / written, more time may actually be required by the Modbus interface before a complete
response is formulated and ready to be returned to the network.
The response delay timer value is read only upon initialization. Therefore, if the delay value is changed,
the drive must be reset for the new value to take effect.
10.2.8 LED Indicators
If the ASD’s “Inverter Number” parameter (F802) is not set to a value between 1 and 247, the Module
Status LED will flash red upon initialization to indicate the configuration error.
Whenever a faulty Modbus packet is detected, the Network Status LED will briefly flash red to indicate
the faulty packet. This can be used as a helpful indicator when communications are not working, and
will usually be the result of incompatible network settings (baud rate, parity, etc.) or reversed RS-485
wires.
10.2.9 Register Summary
Table 25 presents an overview of all accessible information within the entire Modbus register map.
Although the majority of the mapping directly accesses the corresponding ASD registers, not all ASD
registers are available. The specific ASD registers that can be accessed are defined in the Toshiba
ASD
Operation Manual and/or the ASD Serial Interface Manual. In addition, the accessible registers, their
access behaviors and data ranges may vary depending on such issues as the drive’s capacity and control
firmware revision.
Table 24 lists the Modbus registers that access local information on the Multicom interface. These
items are also indicated in Table 25.
