HTL single-ended encoders Circuit characteristics: - threshold low = 3.6 V ... 5.6 V- threshold high = 7.4 V ... 8.2 V- hysteresis = 2.6 V ... 3.6 V- current sink from encoder output high = 2.1mA- current sourced to encoder output low = 0.6mA- maximum input voltage (operation guaranteed, no destruction) = 40V- maximum [...]
Single ended 24V PNP P&D signals adaptation for Fdbk. #1 of iPOS48xy & iPOS80xy In case of a P&D masters that have 24 V PNP outputs, the following adaptation circuit should be used, to connect the pulse and direction signals to the "Feedback #1" connector (set for single ended inputs) of the iPOS4803, iPOS4808, iPOS4806, [...]
The drive's analog inputs can be set to work either in the 0-5 V or in the +/-10 V range. In order to apply a voltage in the 0-20 V range to the drive, you need to set the drive in the 0-5 V voltage range, and use an external circuit to limit the input [...]
Technosoft drives are able to detect a pre-programmed transition on several inputs. When the transition occurs, both the motor position and the master position (where available) are captured and stored in dedicated variables (CAPPOS and CAPPOS2 respectively). Usually, depending on the drive model, there are 2 capture inputs: CAPI and CAP2I. These inputs are very [...]
In case of very long motor and feedback sensor cables please check the following recommendations: Motor connection 1) Mount some inductance in series with the motor wires (immediately after the drive motor output terminals). Remarks: - the additional inductance value should be selected function to the minimum required inductance and to the minimum required electrical [...]
Connecting an encoder to the gearbox instead of the motor shaft is only possible in the following situations: A stepper motor is controlled in open loop A brushed (DC) motor is used A brushless motor equipped with digital hall sensors is used (trapezoidal commutation of the motor) Here are the configurations that need the encoder to be [...]
Sometimes, the current drawn from the power supply (when the motor is controlled by an intelligent drive) is mistakenly viewed as the current through the motor. In order to control the motor current, usually only a fraction of the available DC bus voltage is applied to the motor. This depends on the motor phase resistance [...]
In case of the Technosoft drives with NPN outputs, an NPN to PNP adapter has to be used in order to connect a PNP equipment to their outputs (24 V, 0.5 A minimum). For this adapter, we suggest the schematics below. 1. Using SMD components IN = the NPN output of the Technosoft drive OUT = the PNP output [...]
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 EasyMotion Studio II [...]
