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: 

Encoder cable length =

U - U

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:  dr.23…dr.28, dr.30…32

Asynchronous motors:  dr.0…dr.7

Encoder parameter: 

Ec.1…3, In.31…32

Controller parameter:  cS.19
