HMI acknowledge timeout (P6.7.3)
This function allows the user to change the timeout of the HMI acknowledgement time.
Note! If the frequency drive has been connected to the PC with a normal cable, the default
values of parametres 6.7.3 and 6.7.4 (200 and 5) must not be changed.
If the frequency drive has been connected to the PC via a modem and there is a 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 drive 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 to the [Misc]-part of the
NCDrive.ini file:
Retries = 5
AckTimeOut = 1200
TimeOut = 6000
It must also be considered that intervals that are shorter than the AckTimeOut-time cannot be
used in NCDrive monitoring.
Enter the edit mode by pushing the right arrow menu button. Use the Browser buttons to change
the acknowledgement time. Accept the change with the Enter button or return to the previous level
with the left arrow menu button .

received acknowledgement is faulty.
