INTELLIGENT COMMUNICATION

Parallel or serial link
Parallel BCD output modules with built-in PC-handshake for easy interface to programmable controllers or remote displays is available and can be inserted in slots 4 or 5. The TTL-, PNP-, or NPN-types of BCD outputs allow more flexibility for interface to external devices.

The MINI-PLS Model M1450-300 has been designed to accommodate special modules such as, serial link RS-422A or RS-232C, etc.

Consult factory for availability of special modules.

M1450 MIN1-PLS
ADVANCED FEATURES

Programmable Rate Offset, ROF, for Automatic Speed Compensation 
The M1450 MINI-PLS features a rate offset to compensate for speed variations. This rate offset represents a positive number that varies linearly with RPM. This number is added to the resolver position and is used to advance the PLS settings as a function of the machine speed. Depending upon the selected model, you can program a single rate offset value for a group of 8 channels on a cam module or different rate offset values for up to 16 individual channels.

Dynamic Zeroing, ModZ
The M1450 MINI-PLS features dynamic zeroing or ModZ (Modification Zero) to modify the zero reference point for selected group of channels independent of the actual resolver position. Upon receiving an external signal, the resolver position for the selected ModZ channels is reset to zero. 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. Depending upon the selected model, you can operate up to 4 ModZ cam modules or 32 outputs.

VARIETY OF MODELS TO MEET YOUR APPLICATION NEEDS

Single-Turn Rotary PLS Models 

• SAC-M1250-010

• SAC-M1450-300

• SAC-M1450-MROF

• SAC-M1450-400

The model M1250 is the basic MINI-PLS, whereas all the above M1450 models are the advanced versions of the single­turn rotary PLS. The single turn MINI-PLS is an absolute position programmable limit switch that uses a resolver as input and has built-in tachometer and motion detector.

The model M1250 offers an ultra fast response time of 57 µs. The M1450 Models offer rate offset (ROF) and dynamic zeroing (ModZ) as standard features. Serial communication RS­232C or RS-422A is provided on the model M1450-300. The model M1450-MROF features programmable multiple rate offsets (up to 19), while the model M1450-400 is a high resolution PLS (up to 4096 counts-per-revolution).

Linear PLS with Single-Turn Resolver
Model SAC-M1450-M10

This is a semiabsolute position programmable limit switch that uses a single-resolver as input and has a maximum resolution of 4096 counts-per-revolution. This model is a multi-turn unit that keeps track of number of revolutions and accumulates its position as the resolver shaft rotates. The maximum read out is 999,999. The position is retained on loss of power provided the resolver shaft is not rotated more than 180 degrees while power is off. A preset input is provided to enter a preset number into the memory as a reference position. The ModZ trigger and ModZ enable inputs allow ModZ functions for up to three cam modules. Speed compensation is also provided for all cam modules installed.

Single-Turn Rotary PLC with Brake Wear Monitor Model SAC-M1451-010

Model M1451-010 PLS is an absolute position resolver which accepts input from a single-turn Resolver. It combines a PLS, tach, and motion detector and features a built-in broken-wire detector. It also has MODZ, speed compensation and brake­wear monitoring capability.  At 1800 RPM the micro-scan time is rated 450-905 µs.
