8.7.8.4 Changing the Fan Control Settings
Use these instructions to change the Fan Control Settings.
Procedure
1.
In the Hardware settings submenu, find the Fan control settings (P6.7.2) with the Browser buttons.
2.
To go to the edit mode, push the Menu button Right.
The parameter value starts to blink.
3.
To select the fan mode, use the Browser buttons.
4.
To accept the change, push the [enter] button.
8.7.8.5 HMI Acknowledge Timeout (P6.7.3)
Use this function to change the timeout of the HMI acknowledgement time. Use this function when there is more delay in the RS232
transmission, for example, when internet connection is used for communication over longer distances.
If the AC drive is connected to the PC with a cable, do not change the default values of parameters P6.7.3 and P6.7.4 (200 and 5).
If the AC drive is connected to the PC with an internet connection and the messages are transferred with a delay, set the values for
parameter P6.7.3 to agree these delays.
For instructions, see
8.7.8.6 Changing the HMI Acknowledge
Example
For example, if the transfer delay between the AC drive and the PC is 600 ms, make these settings:
•
Set the value of parameter P6.7.3 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.
8.7.8.6 Changing the HMI Acknowledge Timeout
Use these instructions to change the HMI Acknowledge Timeout.
Procedure
1.
In the Hardware settings submenu, find the HMI acknowledgement time (HMI ACK timeout) with the Browser buttons.
2.
To go to the edit mode, push the Menu button Right.
3.
To change the acknowledgement time, use the Browser buttons.
4.
To accept the change, push the [enter] button.
8.7.8.7 Changing the Number of Retries to Receive HMI Acknowledgement (P6.7.4)
Use this parameter to set the number of times the AC drive tries to receive acknowledgement if it does not receive it during the
acknowledgement time (P6.7.3) or if the received acknowledgement is defective.
Procedure
1.
In the Hardware settings submenu, find the Number of retries to receive HMI acknowledgement (P6.7.4) with the Browser
buttons.
2.
To go to the edit mode, push the Menu button Right. The value starts to blink.
3.
To change the number of retries, use the Browser buttons.
4.
To accept the change, push the [enter] button.
8.7.8.8 Sine Filter (P6.7.5)
When using an old motor or a motor that was not made to be used with an AC drive, it can be necessary to use a sine filter. A sine
filter makes the sine form of the voltage better than a dU/dt filter.
If a sine filter is used in the AC drive, set this parameter to Connected to put it into operation.
