7.3.4.8 Register 25 – SD_CH1_STEPTARGET
Bit Description ECAT PDI Range [Unit]
31:0 Steps pulses (= distance) to be made for
SD_CH1.
Can be overwritten at any time.
When zero, no more step pulses are generated
at output S1 or S1n,
Reading the register returns the remaining
number of step pulses to be generated.

7.3.4.9 Register 26 – SD_CH2_STEPTARGET
Bit Description ECAT PDI Range [Unit]
31:0 Steps pulses (= distance) to be made for
SD_CH2.
Can be overwritten at any time.
When zero, no more step pulses are generated
at output S2 or S2n,
Reading the register returns the remaining
number of step pulses to be generated.

7.3.4.10 Register 27 – SD_CH0_COMPARE
Bit Description ECAT PDI Range [Unit]
31:0 Comparison value to compare with actual value
of SD_CH0_STEPCOUNT.
When both are equal and bit 6 in SD_CFG
is set, the next step rate as configured in
SD_CH0_NEXTSR will be assigned and used for
SD_CH0_SR.
