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)
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.
