In the Hardware Settings submenu (S6.7) under the System menu, you can further control some functions of the hardware in your drive. The functions available in this menu are HMI acknowledge timeout and HMI retry.

HMI Acknowledge Timeout (P6.7.3)

This function allows the user to change the timeout of the HMI acknowledgement time. The drive waits for the HMI acknowledgment in accordance with the value of this parameter.

Note: If the drive 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 drive 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 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 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 pressing Menu Button Right. The current value starts to flash. 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.
