Data exchange with encoder
In this area, you can configure the encoder frame and the criteria for how the encoder data
are to be evaluated. The specifications must match those in the device configuration.
●
Encoder message frame:
In the drop-down list, select the frame of the encoder. The specification must match the
setting in the device configuration.
●
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 fine resolution in the absolute actual value
(GN_XIST2)
In this field, configure the number of reserved bits
for fine resolution within the absolute actual value
(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 fine resolution in the absolute actual value
(GN_XIST2)
In this field, configure the number of reserved bits
for fine resolution within the absolute actual value
(Gn_XIST2).
