The sign bit represets the direction of motor rotation. Finally, two enable inputs are provited on the L pins 12 and active low and high respectively.

L Datasheet PDF –

The L internal reference voltage is also derived from V. Datashet 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. The interval between one side of the bridge switch- ing off and the other switching on.

RC network R20, C17 – pins 11 and 10 where: Total Drop Out Voltage. Speed commands for the system originate in the microprocessor continuosly updated on the motor position by means of pulses from the L tachometer chip, whitch in tur datashest its datasgeet from the op- tical encoder. Input Voltage pin 6. This can be foud from: Using the coparators C. Currently available microproces- sors may generates spikes as high as 1.

These datasyeet may be used for a variety of applications such as motor inhibit during reset of the logical. Voltage and current characteristics: The motor continues to run at rop speed but under closed-loop control. The current sense resistors R18 and R19 should be high precision types maximum tolerance?

From this basic input, the microprocessor computes a 5-bit control word that sets the system speed dependent on the distance to travel The interval between one side of the bridge switching off and the other switching on, t, is programmed by. The large step signal response is limited by slew-rate and inductive load. STMicroelectronics acknowledges the trademarks of all companies referred to in this document.

Sensing Resistor Voltage Drop. No license is granted. Total Power Dissipation T. This section has been added in order to help the designer for the best choise of the values of external. Speed commands for the system originate in the microprocessor.

The previous linear analysis is correct for this example. The system operates in two modes to achieve high speed, high-accurancy positioning.

This publication supersedes and replaces all information previously supplied. However, STMicroelectronics assumes no responsibility for the consequences. These inputs may be used for a variety of applications such as motor inhibit during reset of the dztasheet system and power-on reset see fig.

The output will also be. It is continuosly updated on dahasheet motor. This can be foud from: The error signal obtained by the addition of the input and the current feedback signals pin 7 is used to pulse width modulate the oscillator signal by means of the comparator.

The multiplier outputs, C. This input signals is bidirectional so it must be converted to a positive signal ba- cause the L uses a single supply voltage The second input to each multipler l922 of the sign of the first input of the other multiplier before differentiation, these are obtained using the compa- rators C.

The braking is applied pro. Inhibit Low Level pin 12, The L, L and L are intended to be used as a datadheet microprocessor controlled positioning system. But for a good stability, from relationship.

Currently available microprocessors may generates spikes as high as 1. The optical encoder also provides an output at one position on the disk which is used to datashwet the initial position.

The output will also be inhibited if the supply voltage falls below 18 V. In order to be sure that the current loop is stable the following condition is imposed: TACHO signal and the risulting error signal is amplified by the error amplifier, and subse- quently appears on pin 1. The module of the transfer function is: It is possible to synchronize two L ‘s, if desired, using the network shown in fig.

L datasheet and specification datasheet Download datasheet. Inhibit High Level pin 12, From this basic l229, the microprocessor computes a 5-bit control word that sets the system speed dependent on the distance to travel. The above function is performed by amplifying the input signals in A. This signals are used by the microprocessor to determine the position by counting the pulses.
