(Caution) In case of HRV3
In case of HRV3, you should read 4.3 servo HRV3 control in “FANUC AC SERVO MOTOR α
i series
Parameter Manual”. You should be careful with the followings.
1) Hardware (Servo axis control card, Servo Amplifier, Outer detector I/F unit)
2) Software (CNC software, Servo software)
3) Parameters setting
Case of using HRV3, you must set the parameters of 2
nd
FSSB path (from No.1970 to No.1979).
If you don't use 2
nd
FSSB path, you must set 40 for No.1970 – No.1979.
4) FSSB connection
If the slave unit (Servo amplifier or Outer detector I/F unit) is not suitable for HRV3, you must connect
that slave unit with not the HRV3 path but the other path.
5.1.3
Setting servo parameters (In case semi-closed and 0.1µm :Serial pulse coder A, α1000 or α64)
For the detail, refer to “FANUC AC SERVO MOTOR α
i series Parameter Manual”.
Because all servo parameters (No.2000 - No.2269) are axis type, you should set it for each axis.
(1) Set the following parameters fitted each motor and machine.
• No.2000#1 - #0 set to 01.
• No.2001#7 - #0 set to 00000000.
• No.2020 set to the Motor number.
• No.2021 set to Load Inertia ratio.
• No.2022 set to the motor rotation direction. ( 111 or –111)
• No.2023 set to 819.
• No.2024 set to 1250.
• No.2084 set to SDMR1.
• No.2085 set to SDMR2.
