Note that in practice R must greater than 5. The current sense resistors R18 and R19 should be high precision types maximum tolerance? The previous linear analysis is correct for this example. Input Voltage pin 6. Datashest multiplier outputs, C. The pulse width modulated sig- nal controls the duty cycle of the Hbridge to give an output current corresponding to the L input signal.

These inputs may be used for a variety of applications such as motor inhibit during reset of the logical. The error signal obtained by the addition of the input and the current ,292 signals pin 7 is used to pulse width modulate the oscillator signal by means of the comparator. Input Current pin 6. This signals are used by the microprocessor to determine the position by vatasheet the pulses.

This input signals is bidirectional so it must be converted to a positive signal ba. When the motor is stopped and the microprocessor orders it to a new positio, the system operates initially. The schematic diagram used for the Laplace analysis of the system is shown in fig.

Sensing Resistor Voltage Drop. The transfer function is then. From this basic input, the microprocessor computes a 5-bit control word that sets the system speed dependent on the distance to travel. Currently available microprocessors may generates spikes as high as 1.

Input Current pin 6. Storage and Junction Temperature. But for a good stability, from relationship. This can be foud from: The cutoff frequency is: Speed commands for the system originate in the microprocessor. Total Datzsheet Out Voltage.

This publication supersedes and replaces all information previously supplied. Copy your embed code and put on your site: Currently available microproces- sors may generates spikes as high as 1. The motor continues to run at rop speed but under closed-loop control.

V MB which are fed to the multipliers.

The transfer function 3 can be written as follows: The “one pulse per rotation” opto encoder output is connected to pin 12 of the L FTF where it is. Download datasheet Kb Share this page. It is intended for use, together.

Inhibit Low Level pin 12, Total Power Dissipation T. The interval between one side of the bridge switch- ing off and the other switching on. In order to achieve good stability, the phase margin must be greater than 45? Motor current is regulated by an internal loop in the L which is performed by the resistors R. This is accomplished by the first stage – the level shifter, which uses an internally generated 8 V reference.

The L, L and L are intended to be used as a 3-chip microprocessor controlled positioning system.

The schematic diagram used for the Laplace analysis of the system is shown in fig. Total Drop Out Voltage. 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. Voltage and current characteristics: This signals are used by the microprocessor to determine the position by counting the pulses.

This same reference voltage supplies the triangle wave oscillator whose frequency datashewt fixed by the. This is accomplished by the first stage – the level shifter.
