Parameters which must be set before ending the application settings
The following parameters must be configured for every application.
Parameters Description (parameter name and factory setting (if non-variable) in bold print)
P1800 = 4 Pulse frequency (kHz)
The pulse frequency can be changed in steps of 2 kHz. The range extends from 2 kHz to 16
kHz. The full output current of the converter at 55 °C is 4 kHz.
The highest output frequency is limited by the pulse frequency. With a pulse frequency of 2
kHz, operation up to 133 Hz is possible. If a higher output frequency is required, the pulse
frequency should also be increased (10 kHz pulse frequency - maximum output frequency of
650 Hz).
If no low-noise operation is required, then the converter losses and the high-frequency inter-
ference transmitted by the converter can be reduced by selecting a lower pulse frequency.
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 greater than 50 Hz is required.
Comments: This scaling has an effect on the maximum frequency of the analog setpoints.
Fixed frequencies and standardization processes of the motor potentiometer are related to
100 %.
P2001 = 1000 Reference voltage (V)
The reference voltage in Volt (output voltage) corresponds to a value of 100 %.
Comments: This setting should only be changed if the power must be output with a different
scaling.
P2002 = ? Reference current (A)
The reference current in Ampere (output current ) corresponds to a value of 100 %. The
factory setting equals 200 % of the rated motor current (P0305).
Comments: This setting should only be changed if the current must be output with a different
scaling.
P2003 = ? Reference torque (Nm)
The reference torque in Newton meter corresponds to a value of 100 %. The factory setting
equals 200 % of the rated motor torque which is determined from the motor data for a con-
stant motor torque.
Comments: This setting should only be changed if the torque must be output with a different
scaling.
P2004 = ? Reference power (kW or hp)
The reference power in kW or hp corresponds to a value of 100 %. The factory setting is
200 % of the rated motor torque at constant motor torque.
This setting should only be changed if the power must be output with a different scaling.

Parameters Description (parameter name and factory setting (if non-variable) in bold print)
P0971 = 1 Adopting data from RAM into EEPROM
0: Inhibited
1: All parameter changes are transferred from RAM into EEPROM, i.e. the data are not lost if
there is a power failure.
