(5) Servo parameter initialization
For axes connected to an analog servo circuit, initialize the servo
parameters as listed below.
Parameter number
Series 15i Power Mate i
Name Set value
1804 2000 Initialization bit 00000000
1874 2020 Motor number 50
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 rpm.
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.
(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
Series 15i 1953 ANALOG SERD
Power Mate i 2009
SERD (#0) Specifies whether to enable the dummy serial feedback function as
follows:
0: To disable
1: To enable ← To be set
ANALOG (#4) Specifies whether to enable the analog servo interface function as
follows:
0: To disable
1: To enable ← To be set
Series 15i 1788 Maximum amplifier current
Power Mate i 2165
Specify 0 for the axis to be connected to an analog servo circuit.
