Danfoss VLT Programming Guide

16-18 Motor Thermal
Range: Function:
0 %* [0 - 100 %] View the calculated thermal load on the motor. The cut-out limit is 100%. The basis for calculation
is the ETR function selected in par. 1-90
Motor Thermal Protection .
16-22 Torque [%]
Range: Function:
0 %* [-200 - 200 %] This is a read out parameter only.
Shows the actual torque yielded in percentage of the rated torque, based on the setting of the motor
size and rated speed in par. 1-20
Motor Power [kW] or par. 1-21 Motor Power [HP] and
par. 1-25
Motor Nominal Speed .
This is the value monitored by the
Broken Belt Function set in par. 22-6*.
16-26 Power Filtered [kW]
Range: Function:
0.000 kW* [0.000 - 10000.000 kW]
16-27 Power Filtered [hp]
Range: Function:
0.000 hp* [0.000 - 10000.000 hp]
3.16.4 16-3* Drive Status
Parameters for reporting the status of the frequency converter.
16-30 DC Link Voltage
Range: Function:
0 V* [0 - 10000 V] View a measured value. The value is filtered with an 30 ms time constant.
16-32 Brake Energy /s
Range: Function:
0.000 kW* [0.000 - 10000.000 kW] View the brake power transmitted to an external brake resistor, stated as an instantaneous value.
16-33 Brake Energy /2 min
Range: Function:
0.000 kW* [0.000 - 10000.000 kW] View the brake power transmitted to an external brake resistor. The mean power is calculated on
an average basis for the most recent 120 seconds.
16-34 Heatsink Temp.
Range: Function:
0 C* [0 - 255 C] View the frequency converter heatsink temperature. The cut-out limit is 90 ± 5 °C, and the motor
cuts back in at 60 ± 5 °C.
16-35 Inverter Thermal
Range: Function:
0 %* [0 - 100 %] View the percentage load on the inverter.
16-36 Inv. Nom. Current
Range: Function:
Application
dependent*
[0.01 - 10000.00 A] View the inverter nominal current, which should match the nameplate data on the connected motor.
The data are used for calculation of torque, motor protection, etc.
