600 Motor control mode
(2.5.1)
NXS:
0 Frequency control: The I/O terminal and keypad references are frequency refer-
ences and the frequency converter controls the output fre-
quency (output frequency resolution = 0.01 Hz)
1 Speed control: The I/O terminal and keypad references are speed refer-
ences and the frequency converter controls the motor speed
compensating the motor slip (accuracy ± 0,5%).
2 Torque control In torque control mode, the references are used to control
the motor torque.
3 Speed crtl (closed loop) The I/O terminal and keypad references are speed refer-
ences and the frequency converter controls the motor speed
very accurately comparing the actual speed received from
the tachometer to the speed reference (accuracy ±0.01%).
4 Torque crtl (closed loop) The I/O terminal and keypad references are torque
references and the frequency converter controls the motor
torque.
5 Frequency control (advanced open loop)
Frequency control with better performance at lower speeds.
6 Speed control (advanced open loop)
Speed control with better performance at lower speeds.
601 Switching frequency
(2.5.9)
Motor noise can be minimised using a high switching frequency. Increasing the switch-
ing frequency reduces the capacity of the frequency converter unit.
The range of this parameter depends on the size of the frequency converter:
Type Min. [kHz] Max. [kHz] Default [kHz]
0003—0061 NX_5
0003—0061 NX_2
1.0 16,0 10.0
0072—0520 NX_5 1.0 10.0 3.6
0041—0062 NX_6
0144—0208 NX_6
1.0 6.0 1.5

602 Field weakening point
(2.5.4)
The field weakening point is the output frequency at which the output voltage reaches
the set (ID603) maximum value.
