Honeywell Description of Parameters 173
530 Inching reference 1 6 (2.2.7.27)
531 Inching reference 2 6 (2.2.7.28)
These inputs activate the inching reference if inching is enabled. The inputs also start
the drive if activated and if there is no Run Request command from anywhere else.
The parameter is available for NXP drives only.
532 Enable inching 6 (2.2.7.26)
If you are using the inching function the input value must be TRUE set by a digital signal
or by setting the value of the parameter to 0.2. The parameter is available for NXP drives
only.
533 Inching ramp 6 (2.4.18)
This parameter defines the acceleration and deceleration times when inching is active.
The parameter is available for NXP drives only.
600 Motor control mode 234567 (2.6.1)
NXS:
0 Frequency control: The I/O terminal and keypad references are frequency references
and the frequency drive controls the output
frequency (output frequency resolution = 0.01 Hz)
1 Speed control: The I/O terminal and keypad references are speed references
and the frequency drive controls the motor speed
compensating the motor slip (accuracy ± 0,5%).
2 Torque control (Multi-Purpose Control application only) In torque
control mode, the references are used to control the motor
torque.
The following selections are available for NXP drives in applications 2, 3, 4, 5 and 7.
Selections 5 and 6 are not available in application 6 (Multipurpose Control Application).
3 Speed crtl (closed loop) The I/O terminal and keypad references are speed references
and the frequency drive 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 drive controls the motor torque.
601 Switching frequency 234567 (2.6.9)
Motor noise can be minimised using a high switching frequency. Increasing the switching
frequency reduces the capacity of the frequency drive unit.
The range of this parameter depends on the size of the frequency drive:
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
