DC-MOTOR CONTROLLER EM-362 12-24V 160A
EM-362 is a full bridge DC-motor starter. It is designed to work with low voltage DC-motors (permanent magnet and brushed) in applications where a variety of special functions and settings are needed. Starter has adjustable acceleration and deceleration ramps, enabling the smooth starts and stops. Adjustable current limit protects the motor against overcurrent. Current limitation for braking is also available ( regeneration I-limit ). This driver is specifically designed for 12/24V applications, but it's still able to function when voltage is dropped down to 8V. The driver also has an integrated cooling fan, which improves cooling at continuous driving.
EM-362 has two selectable and settable speeds. This feature can be useful eg. in positioning applications. The FW and BW -inputs control the forward and backward runs. STOP input is used to stop the motor, but individual limit inputs are also available for FW and BW direction end stops, that will cause a motor shutdown. SPEED-2 input activates the presettable speed-2, but it can also be set for use as an analog speed control input (0-5V signal). FAULT terminal operates same time as an input and output. Fault line is internally pulled high (100kohm to Vsupply), but will be pulled down in overheat or conditionally also in current trip situation. If FAULT-line is pulled down externally it will cause a stop and disable a new start. For example it is possible to link FAULT pins of several units together and achieve a synchronous stop this way.
Driving can be done with two selectable control modes, continuous and impulse. In continuous mode the motor runs as long as the command is on. In impulse mode a short command starts the motor, and only a new impulse will change the status. Inputs are divided into two groups, command and limit -inputs. These groups can be individually set to work with NPN (connect to zero control) or PNP (positive voltage control) -logic. The parameters are set digitally with a handheld EM-236 interface unit. With this unit the same settings (adjustments) can also be easily copied to multiple devices. Operation of the controller and some of its functional values can also be monitored with EM-236 interface unit.
