Main parameters used in
analogue to position mode
Startup mode
Choose
" Analogue to position"
Profile Data
All these parameters
can be used to limit the
motion. For example
the maximum torque
or velocity.
Analogue to position
setup
The desired position
range, optional position
offset and hysteresis is
specified here.
The following setup parameters can be necessary or convenient to use in the "Analogue
to position" mode.
Startup Mode
Select "Analogue to Position" Mode in this field.
Analogue to position parameters
This area is used to define the range and offset for the motor movement versus the an-
alogue input (see curve on the previous page).
Profile data
In this mode, the motor movement is fundamentally controlled from the external signal
source, but via the 4 parameters specified in "Profile data" field it is possible to add lim-
itations to speed, etc.
Velocity
The velocity field can be used to limit the maximum speed of the motor. Example - if an
external encoder is producing a frequency which theoretically should give a MAC motor
speed of 10000 RPM, the speed can be limited to 4000 RPM (max. allowed speed for the
MAC). The motor will be unstable and go in error in a short time since it is not able to
run at 10000 RPM. Note that no pulses are lost if the velocity is limited. They are simply
remembered and used when the input frequency falls to a level at which the motor is
able to follow.
