7.4.Send 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 USB/RS485, RS485/RS232C con- verter is used, changeover of sending and receiving data takes much time in the converter process.

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 communica- tion, 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 makes 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 .
