EM-243-PLI DC-MOTOR CONTROLLER 12-48V 50A

Product not available for online order.

EM-243-pli is a full bridge DC-motor starter. It is designed to work with DC-motor in applications where some special functions are needed. Starter has adjustable acceleration and deceleration ramps, which make possible the smooth starts and stops. Adjustable current limit protects motor against overcurrent and it can also be used as an end-stop. This device has also two settable speeds, which are usefull in positioning applications. Control inputs FW and BW start the forward and backward run. STOP is for the motor shut-down. In -PLI version there are also PULSE COUNTER which can be used for end limit use. This counter value keep in memory of card also when power is turned off. SPEED-2 input activates preset speed-2, but it can also be used as input for analog speed control signal 0-5V. FAULT output terminal indicates different failure situations. This pin is normally high, but is pulled down in overheat and conditionally also in current trip situation. DISABLE input disables driver as long as this is pulled down externally. Also it is possible to link fault and disable pins of several units together and achieve a syncronous stop. The BRAKE output can be used to release external magnetic brake or control brake resistor in overvoltage situation.
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 comand starts the motor, and only a new impulse will change the status. There is also few special settings start-kick and auto reverse. The card 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 parameters are set with EM-236 interface unit. Operation of the controller and some of its functional values can also be monitored with EM-236 interface unit.
