32-31 Incremental Resolution
Range:
Function:
1024
*
[1 to
1073741823]
Set the resolution of the incremental
encoder connected to
Encoder 1 interface
(X56). The encoder resolution can be
found on the encoder nameplate or
datasheet.
•
Digital incremental encoder
(parameter
32-30
= [1]): The
resolution must be set in pulses
per revolution.
•
CAN encoder (parameter
32-30
=
[3]):
-
Incremental encoder:
Pulses per revolution
-
Absolute encoder:
Pulses per revolution/4
NOTICE
The parameters for the incremental resolution (
32-01
or
32-31
) are always used, even if the CAN encoder is an
absolute encoder. However, a quarter of the encoder
resolution must be set for a CAN absolute encoder.
The maximum frequency of the encoder signal must not
exceed 410 kHz.
This parameter is only visible when parameter
32-30
is
not set to
[0] None
.
32-32 Absolute Protocol
Specifies the type of absolute encoder connected to
Encoder 1
interface
(X56/X62).
Option:
Function:
[0]
*
None
No absolute encoder is connected.
[4]
SSI
An absolute encoder with SSI interface is
connected.
[5]
SSI with filter An absolute encoder with SSI interface is
connected and the communication/signal is
unstable.

32-35 Absolute Encoder Data Length
Range:
Function:

*
[8-37 Bit] Specifies the number of data bits for the
connected absolute encoder, see encoder
datasheet. This is required for the MCO to
generate the correct number of clock bits.
NOTICE
The parameter is only visible when parameter
32-32
Absolute Protocol
is not set to
[0] None
.
32-36 Absolute Encoder Clock Frequency
Range:
Function:
262.000
*
[78.125–
2000.000 kHz]
Specifies the frequency of the
absolute encoder clock signal
generated by the MCO. Set a
frequency appropriate for the
connected encoder.
NOTICE
The parameter is only visible when parameter
32-32
Absolute Protocol
is not set to
[0] None
.
32-37 Absolute Encoder Clock Generation
Select whether the MCO should generate an absolute encoder
clock signal or not.
Option: Function:
[0]
Off Select this option if more MCOs are connected to the
same absolute encoder and another MCO generates
the clock signal. Only 1 device is allowed to generate
the clock signal and only 1 device (encoder or MCO) is
allowed to generate the data signal when multiple
MCOs are interconnected.
[1]
*
On Select this option if the MCO is the only clock
generator for the connected absolute encoder.
NOTICE
This parameter is only visible when parameter
32-32
Absolute Protocol
is not set to
[0] None
