The braking is applied pro. Currently available microproces- sors may generates spikes as high as 1. The main function on the L is to implement the following expression: The optical encoder also provides an out.
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. Open Loop Frequency Response. This is accomplished by the first stage – the level shifter, which uses an internally generated 8 V reference. Speed commands for the system originate in the microprocessor.
L Datasheet PDF –
The oscillator determines the switching frequency of the output stage and should datasehet in the range 1 to 30 KHz. Input Voltage pin 6. The system operates in two modes to achieve high speed, high-accurancy positioning.
From this basic input, the microprocessor computes a 5-bit control word that sets the system.
Transfer Function Calculation in Application Information. Information furnished is believed to be accurate and reliable.
This signals are used by the microprocessor to determine the position by counting the pulses. The enable inputs were implemented in this way because they are intended to be driven directly by a mi.
Small Signal Step Response normalized amplitude vs. At the time, the microprocessor orders a switch to the position mode, strobe signal at pin 8 of L and within the L drives the motor to a null position, datasgeet it is held by electronic “de-tenting”.
The L internal reference voltage is also derived from V. In DC condition, this is reduced to.
L datasheet and specification datasheet Download datasheet. Thus the mean value of TACHO is proportional to the rotation speed and its polarity indicates the direction of rotation.
The output will also ll292 inhibited if the supply voltage falls below 18 V.
The cutoff frequency is: RC network R20, C17 – datqsheet 11 and 10 where: Total Drop Out Voltage. The large step signal response is limited by slew-rate and inductive load. The device may be used separately – particularly the L motor datashret – but since they will usually. The L, L and L are intended to be used as a 3-chip microprocessor controlled positioning sys. The braking is applied progressively until the motor is running at minimum speed.

This is accomplished by the first stage – the level shifter. No license is granted. 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”.
Inhibit High Level pin 12, This input datasneet is bidirectional so it must be converted to a positive signal ba- cause the L uses a single supply voltage Input Voltage pin 6. Finally, two enable inputs are provited on the L pins 12 and active low and high dafasheet.
Speed commands for the system originate in the dqtasheet. The main function on the L is to implement the. Total Drop Out Voltage. L The system operates in two modes to achieve high speed, high-accurancy positioning. The system operates in two modes to achieve high speed, high-accurancy positioning.
Using the coparators C.
