Main Setup [200]
Section 11-2
Drive Mode [213]
This menu is used to set the control mode for the motor. Settings for the refer-
ence signals and read-outs is made in menu Process source, [321].
•
Speed Mode offers an accurate control of the motor speed independently
of the load. The Speed mode also increases the accuracy of the different
analogue output signals that are related to the motor speed. Speed mode
can also be used if several motors of same type and size are connected in
parallel. Requires all motors to be mechanically connected to the load.
•
Torque Mode can be selected for applications where the motor shaft
torque needs to be controlled independently of the speed.
•
V/Hz Mode, output speed [721] in rpm, is used when several motors in par-
allel of different type or size are connected or if parallel motors are not
mechanically connected to the load.
Communication information
To control the speed of the motor, the VSD needs a reference signal. This ref-
erence signal can be controlled by a remote source from the installation, the
keyboard of the VSD, or by serial or fieldbus communication. Select the
required reference control for the application in this menu
.
Default:
Speed
Speed
0
The VSD is speed controlled. Reference given=speed ref-
erence with ramp. Speed and torque limits can be set.
Using “direct torque control” as motor control method.
Torque
1
The VSD is torque controlled. Reference given=torque ref-
erence without ramp. Speed and torque limit can be set.
Using “direct torque control” as motor control method.
Note
No ramps active in the VSD. Care must be taken.
V/Hz
2
All control loops are related to frequency control.
Note
All the functions and menu read-outs with regard to
speed and rpm (e.g. Max Speed = 1500 rpm, Min
Speed=0 rpm, etc.) remain speed and rpm,
although they represent the output frequency.

The reference signal comes from the analogue inputs of
the terminal strip (terminals 1-22).
Keyboard

Reference is set with the + and - keys on the Control Panel.
Can only be done in menu Set/View reference [310].
