EM-324C-JS1 DC-Motor Controller

EM-324C-JS1 is a full bridge DC-motor starter. It is designed for joystick controlled DC-motor applications. The driver has adjustable acceleration and deceleration ramps, which enable the smooth starts and stops. Adjustable current limit protects the motor against overcurrent and it can also be used as an end-stop. This device has also two settable speeds, separate speed ranges for forward and reverse direction. Control input is specially designed for joystick control. The joystick range calibration is done automatically, when calibration function is activated. Calibration detects forward, reverse and midpoint positions. FAULT terminal has simultaneously both input and output functions, the pin is normally high, but is pulled down in overheat and conditionally also in current trip situation. If FAULT-line is pulled down externally it will cause a stop and prevent it from starting again. For example, it is possible to link fault pins of several units together and achieve a syncronous stop.
There are also special settings as start-kick which can be used in case the device is in danger of being jammed. Limit input can be individually set for NPN or PNP logic.
The parameters settings can be done with various EM- interface unit. Operation of the controller and some of its functional values can also be monitored with interface units.
