EM-A24C is a DC-motor driver module, It's based on EM-241 driver card. This module is PCB mountable and it needs a very small pcb area, because it will be installed vertically. This module has effective H-bridge power stage. The power stage has low EMC emission and it can meet EMC directives for industry and household enviroments without external components. This is big benefit when integrated this module to the "motherboard". Module has two pwm frequency option 2kHz offer more current, and 16kHz is noiseless.
BW and FW are control inputs starts and stop motor, and these mode can be set also with parameter 1 and 5.
Stop input stops with ramp, but not block new start. Stop input can be also work as analog current limit, this mode can be active with set parameter 6 and 7 to 0
Fault input stop immeadetly without ramp and keep stop until disappear. Fault out works also as indication output, it can be set with param. 10
Speed-2 input select presetted speed or it can also work as analog speed input. This input can be set also with parameter 5.
Limit input stops motor, these can be use for example as a end limit input. and these inputs have multiple input logic combinations, which can be set with parameter 3
