1.2 Overall description
1.2.1 Basic modes/functions in the MAC motor
The MAC motor offers the following functions.
- Passive mode.
The motor will be in a completely passive state but communication is active and internal
registers can be set up.
- Velocity mode.
The motor velocity can be controlled using MacTalk software or by sending commands
via the serial interface.
- Position mode
The motor position can be controlled using MacTalk or by sending position commands
via the serial interface.
- Gear mode
The position of the motor is controlled by the multifunction I/O, which is configured as
input. Either a pulse and direction signal can be applied or a quadrature A and B signal
from, for example, an incremental encoder.
This mode is very powerful if the MAC motor is used to upgrade a step motor system or
if the motor is used in electronic gear applications such as a flying saw where an external
encoder tracks the position of a moving object.
- Gear Follow Mode
Same mode as gear mode, except that the input pulses are not buffered so that control
strictly follows the input pulses.
- Analogue Velocity Mode
The motor velocity is controlled by a voltage applied at the ±10V analogue input. This
mode can be used in several applications but typical applications include maintaining var
-
iable but constant speed in feeding mechanisms or as a slave driver in multi-axis systems
with a master position controller for several axes.
- Analogue Velocity (with deadband) Mode.
Same function as Analogue Velocity Mode but a deadband around zero is inserted. The
deadband is +/-600mV. This feature is useful if a potentiometer or similar device is used
to control the speed of the motor, since the motor will be stationary if the input voltage
is almost at zero.
- Analogue Velocity/Gear Mode.
This mode is similar to Gear mode but it is possible to increase or decrease the position
of the motor by adjusting the voltage applied to the ±10V input. A typical application is
feeding mechanisms that require “on-the-fly” adjustment.
- Velocity/Analogue torque Mode.
The motor torque is fully controlled by a voltage applied at the ±10V analogue input.
This mode is useful if the motor is used for winding applications where a constant torque
is required in the process. Another typical application is as a slave driver in multi-axis sys
-
tems with a master position controller for several axes. The update frequency is 521 Hz.
Use Analogue Torque (Direct) if a higher bandwidth is required.
