3.3 Parameters: 1-** Load and Motor
3.3.1 1-0* General Settings
Define whether the adjustable frequency drive operates in
speed mode or torque mode, and whether the internal PID
control should be active or not.
1-00 Configuration Mode
Option: Function:
Select the application control principle to be
used when a remote reference (i.e., via analog
input or serial communication bus) is active. A
remote reference can only be active when
3-13 Reference Site is set to [0] or [1].
[0]
*
Speed
open-loop
Enables speed control (without feedback signal
from motor) with automatic slip compensation
for almost constant speed at varying loads.
Compensations are active but can be disabled in
the Load/Motor par. group 1-0*.
[1] Speed
closed-
loop
Enables Speed closed-loop control with
feedback. Obtain full holding torque at 0 RPM.
For increased speed accuracy, provide a
feedback signal and set the speed PID control.
[2] Torque Enables torque closed-loop control with
feedback. Only possible with “Flux with motor
feedback” option, 1-01 Motor Control Principle .
FC 302 only.
[3] Process Enables the use of process control in the
adjustable frequency drive. The process control
parameters are set in par. groups 7-2* and 7-3*.
[4] Torque
open-loop
Enables the use of torque open-loop in VVC
+
mode ( 1-01 Motor Control Principle ). The torque
PID parameters are set in par. group 7-1*.
[5] Wobble Enables the wobble functionality in
30-00 Wobble Mode to 30-19 Wobble Delta Freq.
Scaled .
[6] Surface
Winder
Enables the surface winder control specific
parameters in par. group 7-2* and 7-3*.
[7] Ext. PID
Speed OL
Specific parameters in par. group 7-2* to 7-5*.
[8] Ext. PID
Speed CL
Specific parameters in par. group 7-2* to 7-5*.
1-01 Motor Control Principle
Option: Function:
Select which motor control principle to
employ.
[0]
*
U/f special motor mode, for parallel connected
motors in special motor applications. When U/
f is selected the characteristic of the control
principle can be edited in 1-55 U/f Charac-
teristic - U and 1-56 U/f Characteristic - F .
[1] VVC+ Voltage vector control principle suitable for
most applications. The main benefit of VVC
plus
operation is that it uses a robust motor model.
[2] Flux
sensorless
Flux vector control without encoder feedback,
for simple installation and robustness against
sudden load changes. FC 302 only.
[3] Flux w/
motor feedb
very high accuracy speed and torque control,
suitable for the most demanding applications.
FC 302 only.
The best shaft performance is normally achieved using either
of the two flux vector control modes
Flux sensorless [2] and
Flux with encoder feedback [3].
This parameter cannot be adjusted while the motor is
running.
NOTE!
An overview of possible combinations of the settings in
1-00 Configuration Mode and 1-01 Motor Control Principle can
be found in section 4.1.1.
1-02 Flux Motor Feedback Source
Option: Function:
Select the interface at which to receive
feedback from the motor.
[0] Motor feedb. P1-02
[1]
*
24V encoder A and B channel encoder, which can
only be connected to the digital input
terminals 32/33. Terminals 32/33 must
be programmed to No operation .
[2] MCB 102 Encoder module option which can be
configured in par. group 17-1*
This parameter appears in FC 302 only.
[3] MCB 103 Optional resolver interface module
which can be configured in par. group
17-5**
[5] MCO Encoder 2 Encoder interface 2 of the optional
programmable motion controller MCO
305.
[6] Analog input 53
