Parameters that must be set in every application
Description
Minimum frequency
0.00 [Hz] factory setting
Enter the minimum frequency (in Hz) at which the motor runs independently of the
frequency setpoint. The value set here applies to CW and CCW rotation.
Maximum frequency
50.00 [Hz] factory setting
Enter the maximum frequency (in Hz) to which the motor is restricted independently of
the frequency setpoint. The value set here applies to CW and CCW rotation.
Rampup time
10.00 [s]
Enter the time (in seconds) in which the motor is to accelerate from standstill to the
maximum frequency (P1082).
If the ramp-up time is too short, alarm A0501 (current limit value) may be output or the
inverter is shut down with fault F0001 (overcurrent).
Rampdown time
10.00 [s]
Enter the time (in seconds) during which the motor is to be decelerated (braked) from
the maximum frequency (P1082) to standstill. If the ramp-down time is too short,
alarm A0501 (current limit value) or A0502 (overvoltage limit value) may be output or
the inverter is shut down with fault F0001 (overcurrent) or F0002 (overvoltage).
End quick commissioning (= start internal motor data calculation)
Description
End quick commissioning
0: No quick commissioning (factory setting)
1: Quick commissioning incl. restoring factory settings
- Calculate the motor data with the quick commissioning parameters
- Restore the factory settings for the I/O
- Restore the factory settings for all other parameters
2: Quick commissioning incl. restoring the factory settings for the I/O.
- Calculate the motor data with the modified quick commissioning parameters
- Restore the factory settings for the I/O
- All the other parameters remain unchanged
3: Quick commissioning with motor data only
- Calculate the motor data with the quick commissioning parameters
- I/O settings remain unchanged
- All the other parameters remain unchanged
When P3900 = 1, 2, or 3, the value for P1082 is written to P2000.
When quick commissioning is being completed, the message "bUSY" is displayed on
the BOP. This means that the system is in the process of calculating the control data
and saving the parameter values in the EEPROM.
Once quick commissioning has been carried out, P3900 and P0010 are set to 0.
When you press "FN" and "P" on the BOP, the actual frequency is displayed.
