EnDat at Channel 1
3.3.6

Encoder line length

The maximum line length is 50 m. It results from the voltage drop of the supply line. The
value is calculated as follows:
3.3.7

Tested encoders

The following EnDat encoder have been tested by KEB on it application:
Linear measurement system LC 481
However, this does not restrict the use of rotary encoder with same specifications of other
manufacturers.
4.

Start-up

After the installation or exchange of an encoder interface some adjustments of the inverter/
servo software have to be done before operation:
• Switch on inverter
• Select application mode
• When using synchronous motors set ud.2 to F5-S
• Select parameter Ec.0 and control whether „EnDat" is entered. The displayed value
has to be confirmed by „ENTER" in any case.
• Select parameter Ec.10 and carry out the same for the 2. encoder interface
• Select parameter Ec.1 and control/adjust the increments per revolution
• Select parameter Ec.38; if automatic read in is not adjusted in Bit 2, read out encoder
data with Bit 0.
• Select parameter Ec.37 and control encoder status.
4.1 EnDat® parameter
The following parameters are stored in the EnDat® encoder and automatically read in
e.g.manually read/write by Ec.38:
Synchronous motors:
Asynchronous motors: dr.0...dr.7
Encoder parameter:
Controller parameter:
