HMI acknowledge timeout (P6.7.3)
This function allows the user to change the timeout of the HMI acknowledgement time in cases where there
is an additional delay in the RS-232 transmission due to use of modems for communication over longer
distances, for example.
Note! If the frequency converter 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 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:
It must also be considered that intervals shorter than the AckTimeOut-time cannot be used in NC-Drive
monitoring.
Enter the edit mode by pushing the
acknowledgement time. Accept the change with the
