HMI acknowledge timeout (P6.7.3)
This function allows the user to change the timeout of the HMI acknowledgement time. The inverter
waits for the HMI acknowledgment in accordance with the value of this parameter.
Note! If the inverter 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 inverter has been connected to the PC via a modem and there is a delay in transferring
messages, the value of parameter 6.7.3 must be set according to the delay as follows:
Example:
 Transfer delay between the inverter and the PC = 600 ms
 The value of par. 6.7.3 is set to
1200 ms
 The corresponding setting shall be entered in the [Misc] part of the file
NCDrive.ini:
(2 x 600, sending delay + receiving
delay)
Retries = 5
AckTimeOut = 1200
TimeOut = 6000
 It must also be considered that intervals shorter than the AckTimeOut time
cannot be used in NC-Drive monitoring.
Enter the edit mode by pressing
Menu button right . The current value starts to blink. Use the
Browser buttons to change the acknowledgement time. Confirm the change with the enter button or
return to the previous level with Menu button left.
