Fault handling by the <strong>DG4S</strong> <strong>series</strong> drives:The possible operation states and their indications are as follows:1.) Controller running - indicates normal operation of the controller.Red LED off.Green LED blinking.Description: This is the indication when there is no fault and the drive is up and running.2.) Limit override - indicates that the set servo error limit is reached.Red LED blinking and Green LED blinking simultaneously.Description: This is a fault condition and occurs if the following servo error gets greater thanthe user set value.3.) Unconnected or faulty encoder – indicates that the encoder is not working properlyGreen LED offRed LED blinking rapidlyDescription: This is a fault condition. The drive detects unconnected and faulty encoder signalsif it sensing an encoder fault it stops operation.4.) Overheat – indicates that the drive’s metal case reached 65°CGreen LED onRed LED blinkingDescription: This is a fault condition and indicates an overtemperature of the drive’s metalcase. When this fault happens the drive cannot be reset until it cools down to under 65°C.5.) Overcurrent – indicates that the current on the motor outputs cannot be limitedGreen LED and Red LED blinking together.Description: This is a fault condition and indicates a short circuit on the motor output or a toolow resistance/inductance of the motor coil.Note1.: Point 2 to 5 are error conditions and the error line of the drive actives in these cases.Note2.: Point 5. is a critical type of fault which cannot be reset using the error/reset lines.For safety reasons if this type of fault happens the device can be reset only with toggling the12v or 5V (which one is used to power the drive) power supply to the drive.
5.1 Installation of drive and physical dimensionsAll dimensions in mm.Figure 4. Drive mounting dimensionsThe drive has four-four 3.5mm mounting holes in the 3mm thick aluminium backplate.The backplate is bent to 90° and is mountable in the vertical and also in the horizontalorientation.The drive’s metal base plate acts as a heat sink for the drive and can become hot under heavycurrent operation. It is recommended to install the drive on a thermally conductive frame, forexample an aluminum plate of at least 1.5mm thickness, to improve cooling and powerdissipation.Use heat transfer paste or a silicon heat transfer sheet to get the best thermal connectionbetween the drive’s metal backplate and external mounting metal frame.The drive has builtin thermal protection, but it is adviced to keep the metal frame as cool aspossible to avoid overheating and unexpected shutdowns.
