THE M1920 PLS
A NEW LEVEL OF COMPACTNESS AND
MODULARITY...
YET ANOTHER MILESTONE IN "HIGHEST PROCESSING POWER AND FEATURES PER
CUBIC INCH" FROM AUTOTECH
Built-in Fault Detector
The Fault Output is normally energized when the M1920 PLS is operating normally and the resolver wiring is intact. If an internal M1920 fault is detected, or the power fails, or one or more of the resolver wires is broken or disconnected, the Fault output will de-energize. Under fault conditions all PLS outputs and the motion output will de-energize.
Built-in Tachometer and Motion Detector
The motion detector is programmed to energize a power relay output when the machine's RPM is between the motion low and high limits. The motion detector output status is indicated on the front panel.

ADVANCED PLS CARD
16 PLS output based upon selectable angle on / angle off or angle on /time off. All channels have their own individual leading edge and trailing edge speed compensation for those who like to tailor reaction time at different speeds for the on time and off time. There are also two Modification to Zero
(ModZ) inputs available. ModZ is used for dynamic zeroing the zero reference point of the resolver position upon input from your device. Upon external input signal, the resolver position is reset for the particular ModZ channel. Thereafter, the position is incremented as the resolver rotates forward and outputs are turned "on" and "off" at the programmed limit settings. This feature is ideal for gluing applications, where the glue-gun must be activated at a certain position after the detection of an upcoming product.
