7.9.7.3
HMI acknowledge timeout (P6.7.3)
Use this function to change the timeout of the HMI acknowledgement time. Use this when
there is more delay in the RS-232 transmission, for example, when modems are used for
communication over longer distances.
NOTE!
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 a cable. If the AC drive is connected to the PC with
a modem and the messages are transferred with a delay, set the values for
parameter 6.7.3 to agree these delays. For example, if the transfer delay between
the AC drive and the PC is 600 ms, make these settings:
Example:
•
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.
