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:
3.2.7

Tested encoders

The following encoders can be used dependent on the interface and control:
Software
Interface
<=1.3
>= 1.4
However, this does not restrict the use of rotary encoder with same specifications of other
manufacturers.

Channel 2

The description of input X3B is depending on the used encoder interface. It is described in
a separate manual.

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.00 and control whether „SSI-SIN/COS" 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
• Depending on the encoder interface and control card (see 3.3.7) control/adjust the
number of increments per rev. (Ec.1), the SSI data code (Ec.43) and the SSI data
word length (Ec.44 and Ec.53).
• Select parameter Ec.37 and control encoder status.
