4.2.2 Setting of Machine Side Encoder
(1) Setting of the machine side encoder specification
【#2225(PR)】 SV025 MTYP Motor/Encoder type
Set the position encoder type, according to the machine side encoder specifications.
bit F-C: pen Position encoder
Relative position scale : pen=4
OSA105ET2A,OSA166ET2NA : pen=6
Serial signal output rotary scale : pen=6
Rectangular wave signal output linear scale : pen=8
Serial signal output linear scale : pen=A
【#2219(PR)】 SV019 RNG1 Sub side encoder resolution
For a ball screw side encoder
OSA105ET2A : RNG1=1000
OSA166ET2NA : RNG1=16000
For a linear scale
Set the number of pulses per ball screw lead in one "kp" increments.
For a rotary scale
Set the number of pulses per revolution in one "kp" increments.
Note that the value must be input in increments of 10K pulses (the 1st digit of the setting value is
"0").
If any restriction is imposed due to the above condition, also set SV117 in one pulse increments.
【#2317(PR)】 SV117 RNG1ex Expansion sub side encoder resolution
To set the resolution of the machine side encoder in one pulse increments, set the number of pulses
of the encoder by 4-byte data in total to SV117 (high-order 16bit) and SV019 (low-order 16bit).
SV117= Quotient of the number of pulses divided by 65536 (If the quotient is 0, set SV117 to -1).
SV019= Remainder of the number of pulses divided by 65536
(SV019 can be set in one pulse increments).
If the NC is C70 and SV019 is greater than 32767, enter the (negative) value obtained by subtracting
65536 from the above remainder in SV019.
