Setting the behavior
You can set the behavior of each analog output in case of a communication interruption in the CoE parameters "Watchdog":
Channel | "Watchdog" |
|---|---|
1 | 0x8030:05 |
2 | 0x8040:05 |
Possible values
Value | Enum | Description |
|---|---|---|
0 (factory setting) | "Default watchdog value" | If the reaction time has elapsed, the watchdog immediately sets the output to the default value (see below). |
1 | "Watchdog ramp" | Linear ramp to the default value (see below). |
2 | "Last output value" | Freezing the value: The output outputs the last value that was received by the controller before the communication was interrupted. |
Setting the default value
You can define the default value in the CoE parameters "Default output":
Channel | "Default output" |
|---|---|
1 | 8030:13 |
2 | 8040:13 |
Ramp
You can define the time to reach the default value when the watchdog behavior is set to the value 1 "Watchdog ramp".
|
| t: time in ms until the default value is reached. ncurrent : the last output value that was received by the controller before the communication interruption. ndefault : default value (CoE parameter 80n00:13). vramp : ramp velocity in digits/ms (CoE parameter 80n00:14). |
