A.3 Parameters
Dependency:
For a thermal power unit overload, an appropriate alarm or fault is output and r2135.15 or r2135.13 set.
Settings, where the pulse frequency is reduced, are not possible if the "Extended torque control" function module
(r0108.1) is activated.
For p0290 = 2, 3:
These responses are only applicable for blocksize power units.
For p0290 = 10:
This response is only applicable for booksize power units.
See also: r0036, r0037
NOTICE
If the thermal overload of the power unit is not sufficiently reduced by the actions taken, the drive is always shut down.
This means that the power unit is always protected irrespective of the setting of this parameter.
Note
Under overload conditions, the current and torque limit are reduced, and therefore the motor is braked and forbidden
speed ranges (e.g. minimum speed p1080 and suppression [skip] speeds p1091 ... p1094) can be passed through.
When the motor data identification routine is selected, parameter p0290 cannot be changed.
For p0290 = 0, 2, 12:
This is setting is only practical if the load decreases with decreasing speed (e.g. for applications with variable torque such
as for pumps and fans).
For p0290 = 2, 3, 12, 13:
The I2t overload detection of the power unit does not influence the response "Reduce pulse frequency".
For p0290 = 10, 12, 13:
The possible load duty cycles, calculated based on the previous model (p0290 = 0, 1, 2, 3) for booksize power units
cannot be transferred in every case. This is the reason that we recommend that you contact our application support
department if you are uncertain about dimensioning the device.
r0296
DC link voltage undervoltage threshold
Data type: Unsigned16
Read permission:
Write permission:
Parameter group:
Unit: V
Description:
Threshold to detect a DC link undervoltage.
If the DC link voltage falls below this threshold, the drive unit is tripped due to a DC link undervoltage condition.
Dependency:
See also: F30003
Note
The actual threshold value depends on the device type and the selected device supply voltage (p0210).
r0297
DC link voltage overvoltage threshold
Data type: Unsigned16
Read permission:
Write permission:
Parameter group:
Unit: V
Description:
Threshold to detect a DC link overvoltage.
If the DC link voltage exceeds the threshold specified here, the drive device is tripped due to DC link overvoltage.
