Drive related protections (can be visualized in Drive Info dialog): 1. Over voltage - in case the motor supply voltage exceeds this value the power stage of the drive is disabled 2. Under voltage - the same as over voltage only that it works the other way around. 3. I2t for drive - this is designed to be [...]
As the motor brakes, the kinetic energy stored into the load (the bigger the system inertia, the higher the energy) will flow back to the power supply through the drive (as our drive is a 4-quadrant one, which allows this to happen). Usually the power supply cannot accept this energy, acting as a wall causing the [...]
Motionless start-up method description [II] The motionless start procedure is basically an algorithm that needs to be tuned to be convergent. It has to converge on the electrical angle on which the motor is positioned at the moment of the motionless start procedure execution.In order to do this, a PI controller is used and is [...]
The tuning procedure consists of the following steps: 1) Set or measure the motor supply voltage. To measure the supply voltage, press the Detect button and open the VDC Detection Test. 2) Tuning is done in the order: first the current controller, then the speed controller (if present), and finally the position controller. 3) For each controller press the Tune & Test button to open the tuning [...]
Details about the Incremental Encoder and Digital Halls configuration - Motor Setup [GB/CM] The incremental encoder and the Hall sensors are configured from the Motor Setup dialog in the EasySetUp/EasyMotion Studio software. Below is a short description of the Encoder Resolution and Direction Test and Hall configuration Detection Test. The Encoder Resolution and Direction Test is opened with the Detect Number of Lines button, while the Hall Configuration Detection Test opens when [...]
The software filter for the encoder inputs is available only for the iPOS family and the iMOTIONCUBE drive. It can be activated and programmed from the "Motor Setup" dialog. The filter is a digital input qualifier algorithm that works as in the graph below. The "GPIO Signal" is either of the encoder signals. The "Output [...]
How to check if the Hall sensors are linear (analog) or digital [II] Many of the brushless motors available on the market today are equipped with Hall effect sensors. Usually, these Hall effect sensors are digital. However, there are certain types of motors equipped with linear (analog) Hall sensors. While Technosoft drives currently use the [...]
Below are presented the most frequent causes for communication errors reported by EasyMotion Studio: 1. Communication port is not working properly. > Solution: Check the communication port settings. 2. Drive gets reset by the power supply voltage drop. This situation can appear if the same power supply is used to for the logic and the motor stage of the drive. If the current demanded [...]
EasyMotion Studio and EasySetUp are able to automatically determine the axis ID of the drive connected to the PC via RS232. This feature is enabled when the Axis ID of drive/motor connected to PC option from Communication Setupdialog is set to autodetect. Communication Setup dialog for EasyMotion Studio Communication Setup dialog for EasySetUp Once it is configured for autodetect, EasyMotion Studio/EasySetUp will determine [...]
