Pulse width mod.: var.speed (AO - subsystem-specific extension)
The Analog Output (AO) object supports following properties of the subsystem-specific extension Pulse width mod.: var.speed.
PWM frequency ✳ |
|
|
|---|---|---|
"PWM frequency" defines the frequency of the PWM output signal. | ||
Output position |
|
| |
|---|---|---|---|
"Output position" defines whether the connected physical output is handled as NO (Normally Open) or NC (Normally Closed). | |||
NO contact | The connected physical output is handled as NO. | ||
NC contact | The connected physical output is handled as NC. | ||
Property ID: 4970 | |||
Process value 1 and Process value 2 ✳ |
|
|
|---|---|---|
"Signal value 1" (X1), "Signal value 2" (X2), "Process value 1" (Y1) and "Process value 2" (Y2) are used to calculate the linear function (f). The linear function is needed to calculate the present value out of the measured signal value.
Unit: Depends on the process value. Range: -1 if the function needed to calculate the present value out of the measured signal value is completely defined by the selected signal type. Example: Ni1000 Any Value ≠-1 if the function needed to calculate the present value out of the measured signal value is not completely defined by the selected signal type. | ||
Drive operating hours ✳ |
|
|
|---|---|---|
"Drive operating hours" represents the accumulated time during which the drive has been running, i.e. during which Present-Value > Present-Value-1. "Drive operating hours" is stored persistently every 4 hours. | ||
