SYSTEM DESCRIPTION
The L290, L291 and L292 are intended to be used as a 3-chip microprocessor controlled positioning sys-
tem. The device may be used separately - particularly the L292 motor driver - but since they will usually
be used together, a description of a typical L290/1/2 system follows.
At the time, the microprocessor orders a switch to the position mode, (strobe signal at pin 8 of L291) and
within 3 to 4 ms the L292 drives the motor to a null position, where it is held by electronic "de-tenting".
The mechanical/electrical interface consists of an
