SV018 PIT Set the pole pitch.
1 to 32767
(mm)
SV019 RNG1 Set the resolution per pole pitch of the detector used for position control. 1 to 9999
(kp/PIT)
SV020 RNG2 Set the resolution per pole pitch of the detector used for speed control. 1 to 9999
(kp/PIT)
SV021 OLT Set the detection time constant for overload 1 (OL1)
Normally, set 60.
1 to 300
(s)
SV022 OLL Set the current detection level of overload 1 (OL1) as a percentage (%) in respect to the stall
rated current.
Normally, set 150.
1 to 500
(Stall rated
current %)
SV023 OD1 Set the excessive error detection width for servo ON.
Setting method
SV023:OD1 = SV026:OD2 = SV053:OD3 =
F / ( 60 × PGN1 ) × 0.5
F : Max. rapid traverse speed (mm/min)
PGN1 : Position loop gain 1 (rad/s)
When 0 is set, the excessive error will not be
detected at servo ON.
0 to 32767
(mm)
SV024 INP Set the in-position detection width.
Normally, set 50.
0 to 32767
