BASIC PLS CARD:

User-friendly Interface
The front mount unit has 2 line x 20 character LCD display for menu driven programming and for providing maximum information on one screen. A 4 digit of LEDs display is provided for displaying machine position, RPM, and other commonly used parameters. The keypad provides hot keys to quickly access different modules. The keypad provides a full numeric keypad for direct entry of numerical information as well as 5 Simple Programming Keys common to several other Autotech products.

Individual Speed Compensation for the first 8 PLS Outputs 
The M1920 PLS features a rate offset to compensate for speed variations. This rate offset represents a positive number that varies linearly with RPM. The rate offset is added to the resolver position and is used to advance the PLS settings as a function of the machine speed. In M1920, the rate offset can be programmed in scale factor units per 100 rpm up to full scale factor value.

Multiple Program Storage Makes Job Changeover Easy The M1920 PLS can store up to 100 independent, user defined PLS programs for different machine setups to reduce down time. job names can be applied to the M1920 PLS programs, then these names can be used through the menus to select, search, rename, copy or even delete the program! This job name will reside on the display with position and RPM to ensure that's the job you're working on.

Intelligence of 6 Microprocessors in Unison
As shown in the block diagram above, M1920 PLS has up to 6 microprocessors performing 6 logically independent tasks, yet working in unison.

Because of the power of 6 microprocessors, M1920 PLS can process all 80 PLS outputs in a mere 280 microseconds at 600 RPM simultaneously.

Built-in Brake Wear Monitor for OSHA Compliance
The M1920 PLS offers a built-in brake wear monitor in the basic unit. The Brake Wear Monitor accepts an input from clutch/brake circuit and measures the stopping time of the press after the brake is applied. If the stopping time, measured in milliseconds, exceeds programmed danger limit, fail safe output is de-energized, which can be used to disable further press operation. If the stopping time exceeds programmed caution limit, the caution output energizes. The brake time can be displayed on the M1920 PLSs 4 digit LED display.

Fine-Tune in Motion
The PLS module is designed for your total convenience. The setpoints can be fine-tuned while the machine is in motion, making machine set up extremely simple. The convenient UP/DOWN arrow keys increment/decrement the setpoints. Supervisory control inputs are provided to prevent unauthorized, and unintentional change of setpoints.

Fully Isolated Inputs and Outputs
All M1920 inputs and outputs are fully isolated from user power sources to provide outstanding electrical noise immunity in harsh industrial environments.
