Setting a non standard SSI encoder

Proceeding: manually configuring the encoder
1. Set p0010 = 4.
This allows the encoder parameters to be accessed.
2. Configure the encoder using the table below.
3. Set p0010 = 0.
Parameter Description
p0400[1] Encoder type selection (Factory setting: 0)
Selects the encoder from the list of encoder types supported by the firmware of the Control Unit.
0 No encoder
3081 SSI, Singleturn, 24 V
3082 SSI, Multiturn 4096, 24 V
p0404[1] Encoder configuration effective (Factory setting: 0000 0000 0010 0000 0000 0000 0000 0000 bin)
Bit Signal name
00 Linear encoder
01 Absolute encoder
02 Multiturn encoder
03 Track A/B sq-wave
09 SSI encoder
12 Equidistant zero mark
13 Irregular zero mark
14 Distance-coded zero mark
21 Voltage level 24 V
p0407[1] Linear encoder grid division (Factory setting: 16000 [nm])
Sets the grid division for a linear encoder.
p0408[1] Rotary encoder pulse No. (Factory setting: 2048)
Sets the number of encoder pulses.
p0410[1] Encoder inversion actual value (Factory setting: 0000 bin)
Bit 00 1 signal: Invert speed actual value
Bit 01 1 signal: Invert position actual value
p0418[1] Fine resolution Gx_XIST1 (in bits) (factory setting: 2)
The parameter applies for the following process data:
Gx_XIST1
•
Gx_XIST2 for reference mark or flying measurement
•
The fine resolution specifies the fraction between two encoder pulses. Depending on the physical measure-
ment principle, an encoder pulse can be broken down into a different number of fractions (e.g. squarewave
encoder: 2 bit = resolution 4).
p0419[1] Fine resolution absolute value Gx_XIST2 (in bits) (factory setting: 2)
p0421[1] Absolute encoder rotary multiturn resolution (factory setting: 4096)
Sets the number of rotations that can be resolved for a rotary absolute encoder.
