How to program the Frequency Converter
Enable
Select [1] to enable the frequency converter to "catch" and con-
trol a spinning motor.
Function:
Select the frequency converter function after a stop command or after
the speed is ramped down to the settings in par. 1-81
Function at Stop [RPM].
Leaves motor in free mode.
Energizes motor with a DC holding current (see par. 2-00
Current).
Function:
Motor Speed Unit is set to [RPM].
Function:
Motor Speed Unit is set to [Hz].
Function:
The frequency converter determines the motor temperature for motor
protection in two different ways:
• Via a thermistor sensor connected to one of the analog or digital
inputs (par. 1-93
• Via calculation (ETR = Electronic Thermal Relay) of the thermal
load, based on the actual load and time. The calculated ther-
mal load is compared with the rated motor current I
the rated motor frequency f
need for a lower load at lower speed due to less cooling from
the fan incorporated in the motor.
If the motor is continuously overloaded and no warning or trip of fre-
quency converter is wanted.
Activates a warning when the connected thermistor in the motor reacts
in the event of motor over-temperature.
Stops (trips) the frequency converter when the connected thermistor in
the motor reacts in the event of motor over-temperature.
