14.28 Applying the Rotary Axis Configuration Parameter
(8) When the rotation center error compensation function is used, note the following conditions as well.
(a) Precautions when the parameter "#1450 5axis Spec/bit5" (Rotation center error compensation: restraint of machine
movement) is set to "1".
- When the rotary axis configuration parameter is switched due to a reset or an emergency stop, the machine may
move because the rotation center error compensation function is immediately enabled in the configuration after the
parameter is switched.
- The rotary axis configuration parameter may not be applied during the rotation center error compensation. In this
case, the "Rotation center error compensation in progress" signal (RCEI: XD15) is turned OFF because the rotation
center error compensation becomes invalid (compensation amount is "0").
(b) When the "Rotation center error compensation enabled" signal (RCEE: YD15) is turned ON without applying the rota-
ry axis configuration parameter, the operation error (M01 0186) occurs. However, if the parameter "#1450 5axis Spec/
bit5" is set to "1", this alarm is not output.
(c) When the "Rotary axis configuration parameter switch request" signal (R2615/bit8) is turned ON during the rotation
center error compensation, the operation error (M01 0187) occurs. However, if the parameter "#1450 5axis Spec/bit5"
is set to "1", this alarm is not output.
When the parameter "#1450 5axis Spec/bit5" is set to "1", if the rotary axis configuration parameter is switched, the
machine may move because the rotation center error compensation function is immediately enabled in the configura-
tion after the parameter is switched. For the sake of safety, issue this command at the position where the rotary axis
angle is 0°.
