Touch.PLS's Resolver Features

Highest Processing Speed

Touch.PLSuses AVG Automation's patented DMA technique, which con-verts the resolver's analog output    signal to a digital form, then compares all the setpoints, and activates all the outputs in less than a  millisecond. The high-speed ratiometric resolver-to-digital converter and the microscan time guar-antees perfect machine operation at speeds up to 1,800 RPM.

Leading- and Trailing-Edge Speed Compensation

Touch.PLSfeatures a Speed Compensation (Rate Offset) to compen-sate for speed variations. The Rate Offset, individually programmable for each channel, is used to advance the PLS settings as a function of the machine speed. In addition, it has 4 channels that have Multislope Speed Compensation, programmable in  16 zones.

Pulse Programming

Touch.PLScan be fine-tuned while your machine is running. Either or both of the ON and OFF Setpoints  can be incremented or decremented, or a fixed dwell can be incremented or decremented, as needed.

Angle ON-Time OFF

Touch.PLScan be programmed to have its outputs turned ON at an angle and turned OFF after a  programmed time by touching the screen. For example, Channel 12 can be turned ON at an angle of 100°  and stay ON for a period of 2.45 seconds.

Programmable Functionality:

Touch.PLSfeatures a dynamic zeroing or Mod-Z (Modification Zero) to modify the zero reference point,  independent of the actual resolver position. After the PLS receives the Mod-Z input, the resolver position is  reset to zero. Touch.PLScan also perform Brake Wear Monitoring to satisfy the OSHA require-ment. This  PLS can be field pro-grammed to have Brake Wear Monitoring Functionality (initiated by entering a Caution  and Danger limit). If you do not select Brake Wear Monitoring, the user must select Mod-Z or the unit  defaults to normal PLS functionality. (If Brake Wear is selected, the unit cannot function as Mod-Z.)

Flexible Group Assignment

TouchPLS's Flexible Group Assignment can be a powerful and useful feature. When it is desirable to  control several different machines linked to the same drive shaft, output channels may be grouped together  into one of five inde-pendent sections. The base group is always PLS, while the other four groups (1-4) may  be defined as PLS or Mod-Z type. Each PLS group has its own group offset, while each Mod-Z group has its own Mod-Z inhibit zone.

Built-in Motion Detector and Tachometer

Touch.PLShas a built-in tachometer and motion detector. The motion detec-tor energizes a relay when the  RPM is between the programmed low and high alarm values.

8-Levels of Password Protection

Touch.PLShas a password protection feature eight levels deep. Up to eight different passwords that are  user-pro-grammable from the touchscreen, allow access to different screens in the Touch.PLS, providing  ultimate protec-tion and security of machine settings.
