5.3 Setting Learning HRV3, HRV4 control
Servo HRV3, HRV4 control is available with Learning series 90D3. The setting bases on standard series,
refer to "FANUC AC SERVO MOTOR α
is / αi / βis series Parameter Manual" (B-65270E). The following
describes about the special points in Learning series.
5.3.1 Setting Learning HRV3 control
Set Learning HRV2 control according to “5.2 Setting High gain parameter”.
No.2013#0 set to 1. (Servo HRV3 control)
No.2334 set to 150. (Current loop gain magnification)
No.2335 set from 100 to 400. (Velocity loop gain magnification)
No.2283#0 set to 1. (High-speed HRV current control with cutting mode)
5.3.2 Setting Learning HRV4 control
Set Learning HRV2 control according to “5.2 Setting High gain parameter”.
No.2004 set to xx0x0011. (Don’t change “x” bit)
No.2014#0 set to 1. (Servo HRV4 control)
No.2040 set to 1.5 times of HRV2 standard.
No.2041 set to 1.5 times of HRV2 standard.
No.2334 set to 200. (Current loop gain magnification)
No.2335 set from 100 to 400. (Velocity loop gain magnification)
No.2283#0 set to 1. (High-speed HRV current control with cutting mode)
Note
This setting is different from standard HRV3, HRV4 setting, and doesn’t require the NC program
"G05.4 Q1" which changes the mode into High-speed HRV current control only during cutting
mode (G01).
Fixed HRV control bit No.2271# 0 set to 1 in order to be High-speed HRV current control mode
at all time regardless of cutting mode (G01) etc.
5.3.3 Setting Learning HRV3 control for Piston lathe, Lead cutting
Piston axis or Turner axis is set parameters referring to Appendix 3. Parameter table for Learning
control. Take care of the parameters No.2003#0 = 1 and No.2004 = 11111010.
Note
This setting is different from standard HRV3 setting, which does not require the NC program
"G05.4 Q1".
This setting is fixed in the high-speed HRV current control mode with not only cutting mode
(G01) but also other mode.
