Description

8LSA43.R0022D100-0 8LS synchronous motors

The motor bridge module MM432 is used to control two DC motors with a nominal voltage of 10 –
24 VDC at a nominal current up to 4 A. The module is also equipped with two ABR channels as
well as six normal digital inputs for creating positioning tasks which are not too complex.
Each motor is controlled with a full-bridge (H-bridge). Therefore, the motors can be moved in
both directions. Each bridge branch has its own supply voltage allowing two different motors with
different voltages to be used. Each channel has current measurement, supply voltage
measurement, and short circuit recognition to ground and to the positive supply voltage. Motor
control takes place using a 16 kHz PWM signal and is therefore mostly noise-free.
A local processor provides the required intelligence and is used for communication with the
higher level CPU. It handles the preparation of the ABR inputs and normal digital inputs, the
control of both motors (each with a PWM signal) and the analog measurements.

The MM432 motor bridge module is designed for control of DC motors in the lower power range
(typ. 80 W). Both directions are possible.
The main areas of use for the module are in those areas where frictional torque and its
compensation play a decisive role. The module is less suited for dynamic control of acceleration
torque (speed, position). The reason for this lies in the structure of a controller for the MM432.
Current and Torque Control
An electronic current controller is implemented on the MM432 module, which is configured by
the PLC CPU. Since the current with the torque is proportional, the module treats torque control
independently.
Acceleration and deceleration of currents ramps can also be configured, and executed using the
module. The current must be monitored by the application so that the motor is not operated in
generator mode. The current value is read and checked to see whether it lies within the negative
range. The module does not have braking resistors.
Another integrated functionality which is possible is configuring a direction dependent motor
cutoff, triggered using the limit switch.
