16-16 Torque [Nm]
Range: Function:
0.0 Nm* [-30000.0 - 30000.0 Nm] View the torque value with sign, applied to the motor shaft. Linearity is not exact between 110%
motor current and torque in relation to the rated torque. Some motors supply more than 160%
torque. Consequently, the minimum and maximum values will depend on the maximum motor cur-
rent, as well as the motor type being used. The value is filtered, and thus approx. 1.3 seconds may
pass from when an input changes value to when the data readout values change.
16-17 Speed [RPM]
Range: Function:
0 RPM* [-30000 - 30000 RPM] View the current motor RPM.
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 ETRElectronic Thermal Overload function selected in par.1-90
Motor Thermal Protection .
16-22 Torque [%]
Range: Function:
0 %* [-200 - 200 %] This is a readout 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*.
3.16.4 16-3* Drive Status
Parameters for reporting the status of the adjustable frequency drive.
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 - 675000.000 kW] View the braking energy transmitted to an external brake resistor, stated as an instantaneous value.
16-33 Brake Energy /2 min
Range: Function:
0.000 kW* [0.000 - 500.000 kW] View the braking energy 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]
