The current sense resistors R18 and R19 should be high precision types maximum tolerance? Speed commands for the system originate in the microprocessor.
L STMicroelectronics, L Datasheet
The interval l92 one side of the bridge switching off and the other switching on, t, is programmed by. The multiplier outputs, C. This section has been added in order to help the designer for the best choise of the values of external. The module of the transfer function is: The above function is performed by amplifying the input signals in A. This is accomplished by the first stage – the level shifter.
STMicroelectronics products are not. The device may be used separately – particularly the L motor driver – but since they will usually. The braking is applied pro. It dztasheet intended for use, together. These inputs may be used for a variety of applications such as motor inhibit during reset of the logical system and power-on reset see fig.

The cutoff frequency is: The pulse width modulated sig- nal controls the duty cycle of the Hbridge to give an output current corresponding to the L input signal. This input signals is bidirectional so it must be converted to datawheet positive signal ba.
All other trademarks are the property of their respective owners. It is possible to synchronize two L ‘s, if desired, using the network shown in fig. The enable inputs were implemented in this way because they are intended to be driven directly by a mi.
These inputs may be used for a variety of applications such as motor inhibit during reset of the logical. The output will also adtasheet. Speed commands for the system originate in the microprocessor. The system operates in two modes to achieve high speed, high-accurancy positioning. Motor current is regulated by an internal loop in the L which is performed by the resistors R. From this basic input, the microprocessor computes a 5-bit control word that sets the system.
L The system operates in two modes to achieve high speed, high-accurancy positioning. It is possible to synchronize two L ‘s, if desired, using the network shown in fig.
The main function on the L is to implement the following expression: The L, L and L are intended to be used as a 3-chip microprocessor controlled positioning sys. The schematic diagram used for the Laplace analysis of the system is shown in fig.
L datasheet and specification datasheet. In order to achieve good stability, the phase margin must be greater than 45?
At the time, the microprocessor orders a switch to the position mode, strobe signal at pin 8 of L and within 3 to 4 ms the L drives the motor to a null position, where it is held by electronic “de- tenting”. Transfer Function Calculation in Application Information. It is continuosly updated on the motor position by means of pulses from the L tachometer chip, whitch in tur gets its information from the optical encoder.
Storage and Junction Temperature. The values shown in the diagram are for a 5.
The L internal reference voltage is also derived from V. This publication supersedes and replaces all information previously supplied.
