INCREMENTAL ENCODER
KEY FEATURES
Most of the incremental encoders produce square waves signals but also sinusoidal signals and can provide travel, position, displacement and velocity information: positional information is relative, this means that it is possible to know both if the axis is rotating and if it is rotating clockwise or counterclockwise; but it is not possible to gather information about the absolute position of the axis.
For this reason the homing operation is always required at the beginning of the process to determine the absolute position of the system (detection of the reference point or zero point). Information is expressed in pulses per revolution (PPR)
ABSOLUTE ENCODER
KEY FEATURES
An absolute encoder is designed to output the absolute position information; it has a unique code pattern, thus it can provide a unique digital code for each angular position of the axis.
The main feature is that it is always possible to know exactly the position of the axis.
For instance, if you turn off the power supply and move the encoder shaft or the device, then at power on the absolute encoder will output the current position of the axis precisely. This means that no homing operation is required to determine the absolute position
LIMIT SWITCH – DIRECT CONTROL
KEY FEATURES
The new accessory provides a higher level of safety and protection for our medium and large frame chain hoists, combining features from LVC chain hoists and high-specification motor-controllers.
KEY FEATURES:
• Missing phase detection monitoring
• Automatic power supply sequence recognition
• DC chain hoist with limit switch
• Only one cable required to each DC hoist
• Directly compatible with EXE Drive DC Controller
HOUR COUNTER
KEY FEATURES
The Hour Counter is an innovative device: it records the real time and lifetime hours, minutes, seconds of operation. Start cycles, real time temperature and relative humidity values as well as the peak temperature and humidity values.
No batteries required. The Hour Counter uses the same power source as the hoist circuit and is activated when the hoist is running, and the information is stored within the onboard RAM. The Hour Counter can be retrofitted to your existing EXE Technology inventory
