Function:
Set the speed at which to activate par.1-80
Function:
Set the output frequency at which to activate par.1-80
Function:
When "High Starting Torque" is activated by setting of par. 1-77 then a protection functionality is
also enabled to prevent the application from running below minimum motor speed e.g. when in
current limit.
If the speed at any time after the start (or during a stop) falls below the value in the parameter,
the drive will trip with an alarm [A49] Speed Limit.
Function:
When "High Starting Torque" is activated by setting of par. 1-77 then a protection functionality is
also enabled to prevent the application from running below minimum motor speed e.g. when in
current limit.
If the speed at any time after the start (or during a stop) falls below the value in the parameter,
the drive will trip with an alarm [A49] Speed Limit.
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
mistor Source
).
• Via calculation (ETR = Electronic Thermal Relay) of the thermal load, based on the actual
load and time. The calculated thermal load is compared with the rated motor current
I and the rated motor frequency f
M,N
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 frequency 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.
