Appendix 1 Explanation of Parameters
【#2218(PR)】 SV018 PIT Ball screw pitch/Magnetic pole pitch
For servo motor:
Set the ball screw pitch. For the rotary axis, set to "360".
For direct-drive motor
Set to "360".
For linear motor
Set the ball screw pitch. (For LM-F series, set to "48")
---Setting range---
For general motor: 1 to 32767 (mm/rev)
- For linear motor 1 to 32767 (mm)
【#2219(PR)】 SV019 RNG1 Sub side encoder resolution
For semi-closed loop control
Set the same value as SV020.
For full-closed loop control
Set the number of pulses per ball screw pitch.
For direct-drive motor
Set the same value as SV020.
For 1000 pulse unit resolution encoder, set the number of pulses in SV019 in increments of 1000
pulse (kp).
In this case, make sure to set "0" to SV117.
For high-accuracy binary resolution encoder, set the number of pulses to four bite data of SV117
(high-order) and SV019 (low-order) in pulse (p) unit.
SV117 = number of pulses / 65536 (when =0, set "-1" to SV117)
SV019 = the remainder of number of "pulses / 65536"
When the NC is C70 and "SV019 > 32767", set "the reminder of above - 65536 (negative number)"
to "SV019".
---Setting range---
When SV117 = 0, the setting range is from 0 to 32767 (kp)
When SV117 ≠ 0
【#2220(PR)】 SV020 RNG2 Main side encoder resolution
Set the number of pulses per revolution of the motor side encoder.
OSA18 (-A48) (260,000 p/rev) ----------- SV020 = 260
OSA105 (-A51) (1,000,000 p/rev) ------- SV020 = 1000
OSA166 (-A74N) (16,000,000 p/rev) ----- SV020 = 16000
For linear motor
Set the number of pulses of the encoder per magnetic pole pitch with SV118.
For direct-drive motor
Set the number of pulses per revolution of the motor side encoder.
For 1000 pulse unit resolution encoder, set the number of pulses to SV020 in increments of 1000
pulse(kp).
In this case, make sure to set SV118 to "0". For high-accuracy binary resolution encoder, set the
number of pulses to four bite data of SV118 (high-order) and SV020 (low-order) in pulse(p) unit.
SV118 = number of pulses / 65536 (when =0, set "-1" to SV118)
SV019 = the remainder of "number of pulses / 65536"
When the NC is C70 and "SV020 > 32767", set "the reminder of above - 65536 (negative number)"
to "SV020".
---Setting range---
When SV118 = 0, the setting range is from 0 to 32767 (kp)
When SV118 ≠ 0
