Further parameters to set before finishing the application commissioning
The following parameters should be configured for each application.
Parameter Description Setting
P1800 = 4 Pulse frequency (kHz)
The pulse frequency can be changed in 2 kHz steps. The range extends from 4 kHz up to
16 kHz. The complete inverter output current at 50 °C is reached with 4 kHz.
The maximum output frequency depends on the pulse frequency. Operation up to 266 Hz is
possible with a pulse frequency of 4 kHz. If a higher output frequency is required, then the
pulse frequency should also be increased (10 kHz pulse frequency - maximum output
frequency of 650 Hz)
If low-noise operation is not required, then the inverter losses and the high-frequency
disturbances emitted by the inverter can be reduced by selecting lower pulse frequencies.
P2000 = 50 Reference frequency (Hz)
The reference frequency in Hertz corresponds to a value of 100 %.
This setting should be changed if a maximum frequency of higher than 50 Hz is required.
NOTE: This scaling acts on the maximum frequency of the analog setpoints, the fixed
frequencies and the motorized potentiometer. All these values refer to 100 %.
P2001 = 1000 Reference voltage (V)
The reference voltage in Volts (output voltage) corresponds to a value of 100 %.
NOTE: This setting should only be changed if it is necessary to output the voltage with another
scaling.
P2002 = … Reference current (A)
The reference current in Amperes (output current) corresponds to a value of 100 %. Factory
setting is 200 % of the rated motor current (P0305).
NOTE: This setting should only be changed if it is necessary to output the current with another
scaling.
P2003 = … Reference torque (Nm)
The reference torque in Newton-meters corresponds to a value of 100 %. Factory setting is
200 % of the rated motor torque, determined from the motor data, for a constant motor torque.
NOTE: This setting should only be changed if it is necessary to output the torque with another
scaling.
P2004 = … Reference power (kW or hp)
The reference power in kW or hp corresponds to a value of 100 %. Factory setting is 200 % of
the rated motor power at constant motor torque.
This setting should only be changed if it is necessary to output the power with another scaling.
Finishing the application commissioning
Parameter Description Setting
P0971 = 1 Transfer data from RAM to EEPROM
0: Disabled (default)
1: Start data transfer, RAM → EEPROM
All of the parameter changes are transferred from RAM (volatile) into the EEPROM
(nonvolatile, settings are not lost with power off).
While the transfer is active, "bUSY" is displayed on the BOP. Once the transfer is completed
P0970 will be set internally to "0" and the "P0970" will be displayed.
Note: Data transfer RAM → EEPROM is not necessary when the commissioning is performed
via the BOP, because all parameter changes via BOP are stored as well in RAM as in
EEPROM immediately.
