7.4.4 Frequency switch-off limit
417 Frequency Switch-off Limit
The maximum permissible output frequency of the frequency inverter can be set to a low frequency
value via parameter
Frequency Switch-off Limit 417. If this frequency limit is exceeded by the Stator
frequency
210 or the Actual frequency 241, the frequency inverter is switched off and error signal
"F1100" is displayed.
Frequency Switch-off Limit
Please comply with the descriptions of parameters
Minimum frequency 418 and Maximum frequen-
cy
419 in chapter 7.5.1.1 “Limits”.
7.4.5 External error
535 Operation mode ext. error
Parameterization of an external error enables switching off or shutting down several frequency invert-
ers at a time if a fault occurs in the plant or the drive. If an error occurs in a frequency inverter, the
error signal can be transmitted via a bus system and the required reaction can be triggered in another
frequency inverter. Parameter
External error 183 can be assigned the logic signal or digital input
signal which is to trigger the external error.
Via parameter
Operation mode ext. error 535, the response to an external error can be configured.
No response to external errors.
1 - Error-Switch-Off
The drive is switched off and the error message “F1454 External Error” is
output if the logic signal or digital input signal for parameter External
2 - Shutdown, Error
The drive is stopped at the current deceleration ramp and the error mes-
sage „F1454 External Error“ is output if the logic signal or digital input
signal for parameter External error 183 is present.
3 -
Emergency-Stop,
Error
The drive is stopped at the set emergency stop ramp and the error mes-
sage „F1454 External Error“ is output if the logic signal or digital input
signal for parameter External error 183 is present.
For setting up external warnings parameters
User Warning 1 1363 and User Warning 2 1364 can be
used. Check chapter 7.6.5.9 “Warning mask, application” for further details.
7.4.6 Motor temperature
570 Operation Mode Motor Temp.
Automatic shut-down of the frequency inverter or the output of a warning message offers protection
against overheating of the motor. For monitoring the motor temperature, a temperature sensor must
be connected to multifunction input 2. Parameter
Operation Mode Motor Temp. 570 must be set
according to the connected temperature sensor.
The motor temperature is evaluated via one of the following temperature sensors:
− Thermal contact (bimetal temperature sensor)
− PTC resistor (motor PTC)
− KTY measuring resistor
− Resistor PT1000
Motor temperature measurement enables:
− monitoring of temperature limits via a thermal contact or PTC resistor or
− temperature measurement, temperature monitoring and temperature display via a KTY measuring
resistor or a resistor PT1000
