(5) Servo parameter initialization
For axes connected to an analog servo circuit, initialize the servo
parameters as listed below.
Parameter number
FS15i FS30i,16i, others
Name Set value
1804 2000 Initialization bit 00000000
1874 2020 Motor ID number
50 (for HRV1)
252 (for HRV2)
1806 2001 AMR 00000000
1820 1820 CMR
1977 2084 FFG (numerator)
1978 2085 FFG (denominator)
Perform the same initialization as for digital servo according to
your machine tool.
1879 2022 Direction of movement 111 (counterclockwise) or −111 (clockwise)
1896 1821 Reference counter
Specify the number of pulses per motor revolution (after FFG) in
the same manner as for the digital servo circuit.
1876 2023
Number of velocity
pulses
Set value = 1536.797 × E
where E is the voltage (V) that corresponds to a velocity
command of 1000 min
-1
.
1891 2024
Number of position
pulses
Specify the number of pulses per motor revolution (before FFG)
in the same manner as for the digital servo circuit.
NOTE
Although difference in HRV setting is not directly
related to analog servo axes, they must be
initialized with the same HRV setting by reason of
the relationship with the settings of other digital
servo axes.
The Series 30i does not support HRV1 control, so
it is necessary to perform initialization with the
motor ID number (252) for HRV2.
(6) Setting the analog servo function
To enable the analog servo function, set the following parameters for
the axes to be connected to an analog servo circuit. (It is also
necessary to enable the dummy serial feedback function.)
#7 #6 #5 #4 #3 #2 #1 #0
1953 (FS15i)
ANALOG SERD
2009 (FS30i,16i)
SERD (#0) The serial feedback dummy function is:
0: Not used
1: Used ← To be set
ANALOG (#4) The analog servo interface function is:
0: Not used
1: Used ← To be set
