In certain cases, when a drive is used in an area susceptible to strong electromagnetic noise, the content of its EEPROM memory can be altered. In order to avoid this issue, the EEPROM memory can be write-protected after downloading the setup table and / or the TML application. This is done in EasySetUp or EasyMotion Studio by selecting Communication | EEPROM [...]
A Technosoft drive can be restored to the factory settings by deactivating the Setup Table and the TML Program stored inside its memory. This operations can be performed through the Command Interpreter window in EasyMotion Studio or Easy SetUp. The Command Interpreter window can be open from the View menu or from the EasyMotion Studio / Easy SetUp graphical menu bar. The Setup Table can be deactivate by writing 0x0001 in the [...]
The "motor current" is the amplitude of the motor phase currents while the "phase current" represents the current measured on each of the motor phases. The picture below shows the motor current and the phase currents in case of a brushless motor, driven in sinusoidal mode. With red line is the current on the A [...]
The Logger is an evaluation tool, included in the EasyMotion Studio / Easy SetUp software, that starts automatically, when the "Run" button is pressed or when the "Start Logger" button is manually pressed. Sometimes these two starting modes are not enough because the Logger needs to be started at a specific point in the program [...]
Technosoft drives are able to exchange data among them. This feature, used in a TML program executed locally on one of the drives, allows the user to build a state machine — and thus eliminate the need for an external host. The variables used for data transfer must be declared on all the axes, in the same [...]
Most Technosoft drives have 3 special inputs: Limit Switch Positive (LSP), Limit Switch Negative (LSN) and ENABLE *. LSP / LSN inputs prevent movements outside of the working area that is defined by the limit switches. The motor will be stopped if it's moving positive and the LSP input becomes active or when it's moving negative and the LSN [...]
The default functionality associated to ENABLE input is to disable the power stage of the drive when it goes in the disabled state. The default functionality is disabled, i.e. the ENABLE input becomes a general purpose input if the following TML instruction is executed by the drive: ENABLE_OFF = 1; The default functionality of the [...]
The values of the user variables are not saved in the EEPROM when the drive is reset or powered OFF. If this necessity occurs then the user can implement this functionality in a TML application. The applicaiton will contain the declaration of the variables and 2 functions - one for saving the variables and the other for restore the variables. After [...]
TML functions are code sequences stored in the TML program of a drive. They are associated to a name (which is the name of the label corresponding to the function) and an address (the start address of the function, i.e. the address of the label where the function starts). When a function is called from within the TML program [...]
Technosoft drives can handle different types of external reference signals: analog, pulse & direction or quadrature encoder. The following steps describe how to configure a Technosoft drive to read the Pulse & Direction inputs as the external source for the position reference: Create a new project/setup based on your drive, motor and feedback type. If you [...]
