How to read analog signals in the range of 0 to 15 or 20 V, instead of the default +/-10 V [II/CM]

2023-02-14T13:59:55+00:00

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 [...]

Detection time for the capture and limit switches inputs transition [II]

2018-09-08T21:33:14+00:00

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 [...]

Recommendations when very long motor and feedback cables are used

2018-09-08T21:34:48+00:00

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 [...]

Can the encoder be connected to the gearbox instead of the motor shaft? [II/CM]

2018-09-08T21:34:43+00:00

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 [...]

Why is the supply current different from the motor current? [II/CM]

2018-09-08T21:35:36+00:00

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 [...]
