HMI acknowledge timeout (P6.7.3)

This function allows the user to change the timeout of the HMI acknowledgement time.

Note! If the frequency converter has been connected to the PC with a normal cable, the default values of parameters 6.7.3 and 6.7.4 (200 and 5) must not be changed.

If the frequency converter has been connected to the PC via a modem and there is delay in transferring messages, the value of par. 6.7.3 must be set according to the delay as follows:

Example:

•Transfer delay between the frequency converter and the PC = 600 ms

•The value of par. 6.7.3 is set to 1200 ms (2 x 600, sending delay + receiving delay)

•The corresponding setting shall be entered in the [Misc]-part of the file NCDrive.ini: Retries = 5

AckTimeOut = 1200 TimeOut = 6000

It must also be considered that intervals that are shorter than the AckTimeOut-time cannot be used in NC-Drive monitoring.

Enter the edit mode by pushing the Menu button right. Use the Browser buttons to change the acknowledgement time. Accept the change with the Enter button or return to the previous level with the Menu button left. See Figure 7-14 for how to change the HMI acknowledgement timeout.
