The G1 collision detection level is SV060 × clG1.
When clG1 is set to 0, the collision detection method 1 will not function

during cutting feed.
15 clt During normal use
Set "0" in bits with no particular description.
Set the regenerative resistor type.
Always set 1000.
Set the load inertia that includes the motor in respect to the motor
inertia. (When the motor is a single unit, set 100%)
%
JL =
Set the resonance frequency to be suppressed. (Valid at 100 or
Hz more).
Set 0 when the filter is not to be used.
Set this when the lost motion compensation timing does not
msec
match. Adjust while increasing the value by 10 at a time.
The lost motion compensation non-sensitive band can be set only
during feed forward control. Set in the low-order 8 bits. The
setting range is 0 to 100. When 0 is set, 2µm will be set. Adjust
the value in increments of 1µm.
Set the fine torque compensation Cy in the high-order 8 bits.
µm
Normally, set 0. Set 255 to use this function.
The following will result when 5 is set as the lost motion
compensation non-sensitive band, and 255 is set as the fine
torque compensation Cy.
255 × 265 + 5 = 65285 65285 – 65536 = –251

Stall %
Set 0 as a standard. Set this when the overshooting

Set the observer filter band (observer pole).
rad/sec Set 600 as a standard, and lower the setting by 50 at a time if
vibration occurs.
Set the observer gain
% Set 100 to 300 as a standard, and lower the setting if vibration
occurs.

Explanation
Meaning when "1" is set
Extended function invalid
The latest two-second estimated
disturbance torque peak value
(3.5ms average value) is displayed at
MPOF on the Servo Monitor screen.
Collision detection method 2 invalid
The value to be set in TCNV is
calculated and displayed at MPOF on
the Servo Monitor screen.
