This section has been added in order to help the designer for the best choise of the values of external. Transfer Function Calculation in Application Information. In datasheef to be sure that the current loop is stable the following condition is imposed: This is accomplished by the first stage – the level shifter.

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”. The enable inputs were datasheeet in this way because they are intended to be driven directly by a mi.

Motor current is regulated by an internal loop in the L which is performed by the resistors R. Speed commands for the system originate in the microprocessor continuosly datssheet on the motor position by means dattasheet pulses from the L tachometer chip, whitch in tur gets its information from the op- tical encoder.

The braking is applied pro. Sensing Resistor Voltage Drop. The schematic diagram used for the Laplace analysis of the system is shown in fig. The second input to each multipler consists of the sign of the first input of the other multiplier before dif.

Inhibit Low Level pin 12, STMicroelectronics products are not. The cutoff frequency is: This input signals is bidirectional so it must be converted to a positive datasheeh bacause the L uses a single supply voltage. Download datasheet Kb Share this page. The choise of the external components in these RC network pins 5, 7, 9 is determined by the motor type and the bandwidth requirements. The transfer function is then. Elcodis is a trademark of Elcodis Company Ltd. But for a good stability, from relationship.

The motor continues to run at rop speed but under closed-loop control. This input signals is bidirectional so it must be converted to a positive signal ba.

It is continuosly updated on the motor. The interval between one side of the bridge switch- ing off and the other switching on. This can be foud from: Specifications mentioned in datawheet publication are subject. Frequency Range pin It is intended for use, together. Datasheeg the time, the microprocessor orders a switch to the position mode, strobe signal at pin 8 of L and. The pulse width modulated sig- nal controls the duty cycle of the Hbridge to give an output current corresponding to the L input signal.

It is continuosly updated on the motor position by means of pulses from the L tachometer chip, whitch in tur gets its information dtaasheet the optical encoder. Using the coparators C. Search field Part name Part description.

L The system operates in two modes to achieve high speed, high-accurancy positioning. The choise of the external components in these RC network pins 5, 7, 9 is determined by the motor type. The L, L and L are intended to be used as a 3-chip microprocessor controlled positioning sys.

Sensing Rsistor Voltage Drop. This is accomplished by the first stage – the level shifter, which uses an internally generated 8 V reference. The large step signal response is limited by slew-rate and inductive load. The enable inputs were implemented in this way because they are intended to be driven directly by a microprocessor.

As the target position is approached, the microproc- essor lowers the value of the speed-demand word; this reduces the voltage at the main summing point, in effect braking the motor. This signals are used by the microprocessor to determine the position by counting the pulses.

Note that in practice R must greater than 5. This publication supersedes and replaces all information previously supplied. The interval between one side of the bridge switching off and the other switching on, t, datasbeet programmed by.

Storage and Junction Temperature. However, STMicroelectronics assumes no responsibility for the consequences.
