2.2 Gear Mode
2.2.1 Gear Mode - overall description
In gear mode, the motor follows a pulse signal applied to the Multifunction I/O terminals.
The ratio between the incoming pulses and the motor movement can be adjusted to a
desired value. A ratio from 1024:1 down to 1:1024 can be selected. Typically this mode
is used if the MAC motor is incorporated into an application where movement needs to
be synchronized with an external movement. Another typical application is the replace
-
ment of step motors, since the MAC motor in Gear Mode can work like a step motor
using pulse and direction.
The following setup must be done to operate in gear mode (listed according to impor-
tance).
Startup Mode Select Gear Mode in this field.
Gear Factor This field defines the ratio between incoming pulses and the motor
movement. If the preferred motor direction needs to be reversed, the
sign in the “output” field must be inverted. Example: 1024 must be -
1024 to reverse the direction of movement.
Input/Outputs The multifunction I/O terminals must be set to “pulse input” since gear
mode uses the incoming pulses at this input to control the motor
movement. Also the “Input type” must be selected. Choose “Quadra
-
ture” if an incremental encoder is connected or “pulse-direction” if it
is a step motor signal. See also
Multifunction I/O general description,
page 115.

Input/Outputs
The must be setup as pulse input. I/O Type
The must also be setup for the input type
actual pulse type (quadrature or pulse/dir.).
Motor status
This field shows the
actual motor load,
position and speed etc.
Inputs
This field shows the
actual supply voltage
and velocity at pulse
input
