(3) Setting parameters (<2> Used as a separate detector)
After performing the initialization procedure (full-closed loop) described in
FANUC AC SERVO MOTOR α
i/ βi series PARAMETER MANUAL
(B65270EN/05) Subsection 2.1.3, change the settings described below
according to the signal pitch of the detector.
[Setting flexible feed gear]
1977 (FS15i)
Flexible feed gear (numerator) (N)
2084 (FS30i,16i)
1978 (FS15i)
Flexible feed gear (denominator) (M)
2085 (FS30i,16i)
Set a value listed in the following table according to the detector used.
Detector Flexible feed gear (N/M)
Amount of movement per detector revolution [deg]/
detection unit [deg]
αiCZ 512S
500,000
αiCZ 768S
Amount of movement per detector revolution [deg]/
detection unit [deg]
750,000
Amount of movement per detector revolution [deg]/
detection unit [deg]
αiCZ 1024S
1,000,000
[Setting number of velocity pulses]
1876 (FS15i)
Number of velocity pulses (PULCO)
2023 (FS30i,16i)
Set the number of velocity pulses to 8192.
[Setting number of position pulses]
1891 (FS15i)
Number of position pulses (PPLS)
2024 (FS30i,16i)
Set a value listed in the following table according to the detector used.
Detector Number of position pulses
αiCZ 512S
6250 × (gear reduction ratio from the motor to table)
αiCZ 768S
9375 × (gear reduction ratio from the motor to table)
αiCZ 1024S
12500 × (gear reduction ratio from the motor to table)
If the calculation result is greater than 32767, use the following position pulse
conversion coefficient (PSMPYL) to obtain the parameter value (PPLS).
