8.7.8.5 HMI Acknowledge Timeout (P6.7.3)
Use this function to change the timeout of the HMI acknowledgement time. Use this function when there is more delay in the RS232
transmission, for example, when internet connection is used for communication over longer distances.
If the AC drive is connected to the PC with a cable, do not change the default values of parameters 6.7.3 and 6.7.4 (200 and 5).
If the AC drive is connected to the PC with an internet connection and the messages are transferred with a delay, set the values for
parameter 6.7.3 to agree these delays.
For instructions, see 8.7.8.6 Changing the HMI Acknowledge
Example:
For example, if the transfer delay between the AC drive and the PC is 600 ms, make these settings:
• Set the value of parameter 6.7.3 to 1200 ms (2 x 600, sending delay + receiving delay)
• Set the [Misc]-part of the file NCDrive.ini to agree with the settings:
- Retries = 5
- AckTimeOut = 1200
- TimeOut = 6000
Do not use intervals shorter than the AckTimeOut-time in the NC-Drive monitoring.
