Data exchange with encoder
In this area, you can configure how the encoder data are to be evaluated. The specifications
must match those in the device configuration.
●
Encoder message frame:
The encoder data can be transferred only with encoder message frame 83.
●
Encoder type:
Depending on the selected encoder type, configure the following parameters:
Encoder type
Rotary incremental
Steps per revolution: In this field, configure the number of steps that
the encoder resolves per revolution.
Bits for fine resolution in the incremental actual
value (Gn_XIST1)
In this field, configure the number of bits for fine
resolution within the incremental actual value
(Gn_XIST1).
Encoder type
Rotary absolute
Steps per revolution: In this field, configure the number of steps that
the encoder resolves per revolution.
Number of revolutions: In this field, configure the number of revolutions
that the absolute value encoder can detect.
Bits for fine resolution in the incremental actual
value (Gn_XIST1)
In this field, configure the number of reserved bits
for fine resolution within the incremental actual
value (Gn_XIST1).
Bits for the multiplication factor of the absolute
value of the fine resolution (Gn_XIST2)
In this field, configure the number of reserved bits
for the multiplication factor of the absolute value
of the fine resolution (Gn_XIST2).
Encoder type
Rotary cyclic absolute
Steps per revolution: In this field, configure the number of steps that
the encoder resolves per revolution.
Number of revolutions: In this field, configure the number of revolutions
that the absolute value encoder can detect.
Bits for fine resolution in the incremental actual
value (Gn_XIST1)
In this field, configure the number of bits for fine
resolution within the incremental actual value
(Gn_XIST1).
Bits for the multiplication factor of the absolute
value of the fine resolution (Gn_XIST2)
In this field, configure the number of reserved bits
for the multiplication factor of the absolute value
of the fine resolution (Gn_XIST2).
