Danfoss VLT AFE 302 - Parameters: 4-** Limits;Warnings

5.3 Parameters: 4-** Limits/Warnings
5.3.1 4-9* Output Limits
4-90 Output Frequency Deviation Function
Option: Function:
Select the time-out function. The time-out function
activates when the output frequency exceeds the
deviation limit set in par. 4-91 for the time set in
par. 4-92.
[0] * Trip Generate an alarm trip when a fault condition is
encountered.
[1] Warning Generate a warning when a fault condition is
encountered.
[2] Disabled Take no action on fault condition.
Select which reaction the AFE should take in case the
frequency deviation set in par. 4-91 is exeeded.
4-91 Output Frequency Deviation Limit
Range: Function:
20%* [1 - 50%] Selects the max deviation in procentage from
the nominiel mains frequency set in par. 40-01.
4-92 Output Frequency Deviation Timeout
Range: Function:
0.001 s* [0.000 - 60.000 s] Selects the max time where the
frequency deviation set in par. 4-91
can be exceeded.
4-93 Output Voltage Deviation Function
Option: Function:
Select the time-out function. The time-out function
activates when the output vontage exceeds the
deviation limit set in par. 4-91 for the time set in
par. 4-92.
[0] * Trip Generate an alarm trip when a fault condition is
encountered.
[1] Warning Generate a warning when a fault condition is
encountered.
[2] Disabled Take no action on fault condition.
Select which reaction the AFE should take in case the voltage
deviation set in par. 4-94 is exeeded.
4-94 Output Voltage Deviation Limit
Range: Function:
20%* [1 - 50%] Selects the max deviation in procentage from
the nominiel mains voltage set in par. 40-00.
4-95 Output Voltage Deviation Timeout
Range: Function:
0.001 s* [0.000 - 60.000 s] Selects the max time where the
voltage deviation set in par. 4-94 can
be exceeded.
