90.02 ENCODER 2 SEL
Activates the communication to the optional encoder/resolver interface 2.
For selections, see parameter
Note: The counting of full shaft revolutions is not supported for encoder 2.
90.03 EMUL MODE SEL
Enables the encoder emulation and selects the position value and the TTL output used in the
emulation process.
In encoder emulation, a calculated position difference is transformed to a corresponding number of
TTL pulses to be transmitted via the TTL output. The position difference is the difference between the
latest and the previous position values.
The position value used in emulation can be either a position determined by the drive software or
a position measured by an encoder. If drive software position is used, the source for the used position
is selected by parameter
recommended that actual position is always taken from an encoder. Drive software is recommended
to be used only with position reference emulation.
Encoder emulation can be used to increase or decrease the pulse number when TTL encoder data is
transmitted via the TTL output, eg, to another drive. If the pulse number requires no alternation, use
encoder echo for data transformation. See parameter
emulation and echo are enabled for the same FEN-xx TTL output, the emulation overrides the echo.
If an encoder input is selected as emulation source, the corresponding selection must be activated
either with parameter
The TTL encoder pulse number used in emulation must be defined by parameter
NR. See parameter group 93.
