Digitax HD M753 Control User Guide
Issue Number: 3
* This feedback device provides very low resolution feedback and should not be used for applications requiring a high level of performance.
Due to the low resolution of UVW communication only encoders, it is recommended that the
P1 Feedback Filter
(03.042) is set to its maximum value.
A value of 1 ms to 2 ms may also be required in the
Current Reference Filter
(00.017) and it is also recommended that the speed loop gains are set
to a low value to obtain stable operation.
Absolute SSI communications only encoder, or Absolute Sincos encoder with SSI communications
Device Type
(03.038)
SSI
(10) for a SSI communications only encoder
SC SSI
(11) for a Sincos encoder with SSI serial communications
Supply Voltage
(03.036)
5 V
(0),
8 V
(1) or
15 V
(2)
Rotary Line Per Revolution
(03.034)
Set the number of sine waves per revolution of the encoder
SSI Binary Mode
(03.048)
Off = Gray Code
On = Binary Mode
Rotary Turns Bits
(03.033)
Set to the number of turns bits for the encoder (this is normally 12 bits for a SSI encoder)
Comms Bits
(03.035)
Total number of bits of position information (this is usually 25 bits for a SSI encoder)
Comms Baud Rate
(03.037)
100 k, 200 k, 300 k, 400 k, 500 k, 1 M, 1.5 M, 2 M, 4 M
Error Detection Level
(03.040)
So for example, to enable the wire break and phase error detection, set Pr
03.040
to 0011.
