Setting function of communication waiting time ()
Use this function for the following case:
When the data response from the inverter is too quick after the PC had sent the data to the inverter,
PC process cannot get ready to receive the data, or when the RS485/RS232C converter is used,
changeover of sending and receiving data takes much time in the converter process.
The case of " Inter-drive communication ", set up more than 0.03 seconds as a transmitting interval
on the master side to wait for the processing time on the slave side(
= ).
* This function, however, does not operate in case the MODBUS-RTU protocol is selected in com-
munication protocol selection. (
=)
Functional specification:
A time for sending data is prolonged longer than the preset time, until the inverter returns the data to
the PC, after it finishes receiving the data (in case of an inter-drive communication, until the inverter
returns the next data to the PC, after it has sent the data.) In case the inverter's processing capacity
requires longer setting time, the value more than this time will be the set value. (The parameter mak-
es the inverter wait for more than the set time.)
Setting range:
to seconds (10ms to 2000ms)
If the set value is
, this function becomes invalid and the interval time for sending data is set to the
maximum capacity of the inverter. To obtain a quick response for sending data, set value
.

This parameter allows you to write any data, e.g., the serial number of each inverter or parameter
information, which does not affect the operation of the inverter.
