Parameters to set before finishing the application setting
The following parameters should be configured for each application.
Parameter Description (Parameter name and factory setting (if not variable) in bold) 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 is limited by 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, fixed frequencies
and motorized potentiometer normalization operations are referred 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 Apmeres (output current) corresponds to a value of 100 %. Factory
setting is 200 % of the rated motor current (P0305).
NOTE: This setting should only changed if it is necessary to output the current with another
scaling.
P2003 = ? Reference torque (Nm)
The reference torque in Newton-metres 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 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
ther rated motor power at constant motor torque.
This setting should only be changed if it is necessary to output the power with another scaling.
