Dual outputs

Two separate encoders can be combined into one and the same cover.

This solution provides added safety in the form of redundancy, the outputs are

based on two separate scanning LED:s and electronic circuits. The outputs are

galvanically insulated from each other and may be connected to two separate

systems for dierent functions or for redundancy.

MODULARITY

Sine wave signals

Sine waves are an alternative form of output signal. The analogue signal produces a

unique amplitude for each position on the wave, allowing interpolation and very high

resolutions. The interface 1 Vpp is often used in safety-critical applications where

detection is required of extremely small movements.

 Available in model 801, 803, 850, 861 and 862

Digital speed over PROFIBUS

With this option the encoder has two dierent connections, one with a standard

incremental output and another for communication over PROFIBUS.

The standard incremental pulse output is used for connection to the inverter for

direct speed control, while the additional PROFIBUS output can be connected to

another system where a reference value of the speed is required. The speed is calcu-

lated internally in the encoder and is sent over the eldbus.

 Available in model 850, 861 and 862

Optolink transmission integrated

System for transmission of incremental encoder signals in an optical bre can be

integrated into the encoder. This is suitable for use in environments with high elec-

tromagnetic disturbances, transmission of signals over long distances (up to 1,5 km)

and where galvanic insulation is required.

 Available in model 801, 803 and as a separate Optolink module

(CRG Optolink)

ADS Uptime – more data, more control

ADS Uptime is Leine Linde’s most recent advanced diagnostic system, which ena-

bles more control over both the encoder and its immediate environment, such as

the motor installation. Forestall problems before they occur. Get detailed data for

scanning quality, frequency, time in motion, and vibration in both radial and axial

directions. ADS Uptime continuously records and stores data, and gives a warning

or an alarm anytime something outside the set specications occurs.

ADS Uptime can be used with an app on a mobile device for wireless service check-

up (via Bluetooth) and/or connected via OPC-UA to the systems of your choice.

 Available in model 850, 861 and 862

ADS Online – enables predictive maintenance

ADS Online is an advanced diagnostic system that not only monitors the encoder

key functions, but also the ambient environmental parameters, such as supply

voltage, vibration, and temperature. ADS Online also records and stores data,

and gives a warning or an alarm anytime something outside the set specications

occurs. The encoders can be connected to an Ethernet network to provide access

to diagnostics and analysis.

 Available in model 801, 803, 850, 861 and 862

ADS Classic – built-in condition monitoring functionality

ADS Classic is the advanced diagnostic system that continuously monitors

the encoder functions. If serious deviations are detected, a warning is transmitted,

enabling action to be taken. This system is integrated into the encoder and is used

in applications with high demands for reliability, for example, in motors for continu-

ous operation at a paper mill.

 Available in model 801, 803, 841, 850, 861 and 862
