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 AC 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 AC drive 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 AC 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 must be entered in the [Misc]-part of the file NCDrive.ini:
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 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.
Figure 80. HMI acknowledge timeout
Number of retries to receive HMI acknowledgement (P6.7.4)
With this parameter you can set the number of times the drive will try receive acknowledgement if
this does not succeed within the acknowledgement time (P6.7.3) or if the received
acknowledgement is faulty.
Enter the edit mode by pushing the Menu button right. The present value shown starts to blink. Use
the Browser buttons to change the amount of retries. Accept the change with the Enter button or
return to the previous level with the Menu button left.
See Figure 80 for the procedure of changing the value.
