The transfer function 3 can be written as follows: At the time, the microprocessor orders a switch to the position mode, strobe signal at pin 8 of L and. This signals are used by the microprocessor to determine the position by counting the pulses. The current sense resistors R. This same reference voltage supplies the triangle wave oscillator whose frequency is fixed by the external.

Total Power Dissipation T. The second input to each multipler consists of the sign of the first input of the other multiplier before dif. Storage and Junction Temperature. Inhibit Low Level pin 12, 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 second input to each multipler consists of the sign of the first input of the other multiplier before differentiation, these are obtained using the compa- rators C.

The “one pulse per rotation” opto encoder output is connected to pin 12 of the L FTF where it is squared to give the STF logic output for the micro- processor. The interval between one side of the bridge switch- ing off and the other switching on. Currently available microprocessors may generates spikes as high as 1. The enable inputs were implemented in this way because they are intended to be driven directly by a mi.

TACHO signal and the risulting error signal is amplified by datashfet error amplifier, and subse- quently appears on pin 1. Small Signal Step Response normalized amplitude vs. The output will also be.

It is continuosly updated on the motor. C 17 in the diagram.

Inhibit High Level pin 12, The main function on the L is to implement the following expression: Frequency Range pin The cutoff frequency is: The system operates in two modes to achieve high speed, high-accurancy positioning.

The optical encoder also provides an out. Using the coparators C. The enable inputs were implemented in this way because they are intended to be driven directly by a microprocessor. Currently available microproces- sors may generates spikes as high as 1. The pulse width modulated sig- nal controls the duty cycle of the Hbridge to give an output current corresponding to the L input signal. 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 gets its information from the op- tical encoder.

Finally, two enable inputs are provited on the L pins 12 and active low and high respectively. Speed commands for the system originate in the microprocessor. This input signals is bidirectional so it must be converted to a positive signal bacause the L uses a single supply voltage. The above function is performed by amplifying the input signals in A. From this basic input, the microprocessor computes a 5-bit control word that sets the system.

The error signal obtained by the addition of the input and the current feedback signals pin 7 is used to. This input signals is bidirectional so it must be converted to a positive signal ba- cause the L uses a single supply voltage The optical encoder also provides an output at one position on the disk which is used to set the initial position.

Thus the output stage may be inhibited by taking pin 12 high or by taking pin 13 low.

Input Voltage pin 6. Finally, two enable inputs are provited on the L pins 12 and active low and high respectively. Sensing Resistor Voltage Drop. L datasheet and specification datasheet Download datasheet. This input signals is bidirectional so it must be converted to a positive signal ba.

The system operates in two modes to achieve high speed, high-accurancy positioning. Inhibit Low Level pin 12, dstasheet C17 in conjuction with an internal resistor Rt.
