The ELS Basic is a control system that sends signals to motors and can thus set the axes of a
lathe in motion. In order for this movement, which is important for lathes, to take place syn-
chronously with the spindle rotation, a feedback signal from the spindle is required. It provides
the decisive signal.
The following components are required for a functional machine:
ENCODER
●
An incremental encoder must be mounted on the main spindle.
●
An incremental encoder generates pulses that indicate the rotation speed and direction.
The signal must be differential, the encoder must therefore have connections A, A/, B and
B/ and must be able to operate with 5V. An index signal is not necessary.
●
We recommend the type AMT 103-V as it can be mounted on many shaft diameters and the
pulse rate is adjustable.
●
Select the pulse rate of the encoder so that [pulse rate] * [spindle speed] is < 1,200,000
Example: Speed=3000 rpm, 400 pulses/rev: 3000x400 = 1.2000.000, which is fine.
●
If the pulse rate is too high this can overload the control! The maximum possible speed can
then be reduced.
●
The following pulse rates are recommended with a ratio [spindle : encoder] of 1:1 and 2:1:

●
For installation via toothed belt and a transmission ratio deviating from 1:1, the pulse rate
must be selected accordingly (see table above).
●
The pulse rate delivered to the ELS per spindle revolution must be entered in the control
settings before starting operation.
●
Encoders can be connected directly to terminals or via the Rocketronics „Incremental Line
Driver“ with an Ethernet patch cable (CAT5 or better, S-FTP e.g.) to the RJ45 connector. See
