EM-363A is a full bridge DC-motor starter. It's designed to work with a DC-motor in applications where some special functions are needed. Starter 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 also has two settable speeds, which are useful in positioning applications. Control inputs FW and BW start the forward and backward run. STOP is for the motor shut-down but there are also individual limit inputs available for FW and BW directions. SPEED-2 input activates preset speed-2, but it can also be used as an input for analog speed control signal 0-5V. STOP input can be set to work as current limit setting. FAULT terminal has both input and output functions. The pin is normally up, but is pulled down in overheat and conditionally in current trip situation. If FAULT-line is pulled down externally, it will cause a stop and prevent a new start. For example, it's possible to link fault pins of several units
together and achieve a synchronous stop. The device also has parameters for pwm frequency select and freewheel, which is used to release the shaft of the motor. Notice that 16kHz pwm frequency is more silent, but the output current is smaller! Device version A has added Rs-485 Modbus RTU for monitoring and controlling device.
There are two selectable control modes, continuous and impulse. In continuous mode the motor runs as long as the control is active. In impulse mode a short command starts the motor and only a new impulse will change the status. There are also a few special settings, start-kick and auto reverse. The device has selectable input logics. Inputs are divided in two groups, control and limit -inputs. Groups can be individually set for NPN or PNP logic.

The device has black metal housing and lockable spring gage connectors. These connectors are designed for industry and automotive use. Device can be installed laterally or vertically with screw fastening or optionally with DIN-rail fastener. For parameter settings there are the following options: EM-236 interface unit, EM-268 with EmenTool-Lite PC-program and EM-326 with EmenTool-App application for smartphone.
