dependent*
Function:
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
Function:
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 Nominal Speed
par. 1-25 .
This is the value monitored by the
Function:
Function:
Function:
View a measured value. The value is filtered with an 30 ms time constant.
Function:
View the brake power transmitted to an external brake resistor, stated as an instantaneous value.
Function:
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.
Function:
View the frequency converter heatsink temperature. The cut-out limit is 90 ± 5 °C, and the motor
cuts back in at 60 ± 5 °C.
Function:
View the percentage load on the inverter.
Function:
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.
