1. AXIS CONTROL
B-64693EN-1/01
- 106 - NOTE 4 This function cannot be used together with the bit 0 (RVSx) of parameter No. 1815 = 1 that save rotary data by CNC, in the case of a rotary axis B type whose movable range is over one rotation. 5 In this function, the amount of one rotation of rotary axis assumes 360, and the machine position 0 assumes the reference position. It is not possible to apply to a rotary axis other than the above-mentioned setting. 6 Set the parameter No. 1240 to 0.

#1 CRFx When the servo alarm SV0445 (soft disconnection), SV0447 (hard disconnection (separate)), or SV0421 (dual position feedback excessive error) is issued: 0: The reference position established state is not affected. 1: The reference position unestablished state is assumed. (Bit 4 (APZ) of parameter No. 1815 is set to 0.)
1860
Value 1 for the zero point of the absolute position detector
1861
Value 2 for the zero point of the absolute position detector
1862
Value 3 for the zero point of the absolute position detector
NOTE When this parameter is set, the power must be turned off before operation is continued.
[Input type] Locked parameter
[Data type] 2-word axis Parameters Nos.1860 to 1862 are values for the zero point of the absolute position detector (association with reference position and the counter value of the absolute position detector). The CNC automatically sets parameters Nos.1860 to 1862 when correspondence between the reference position and the absolute position detector is performed. It is not available to set parameters Nos.1860 to 1862 by using inputting of MDI operation, FOCAS2, PMC window or programmable parameter input(G10).
The zero point data of the absolute position detection can be restored and parameters Nos.1860 to 1862 can be set, by the parameter input from connected I/O unit or by restoring the SRAM area of boot system. When the zero point data of the absolute position detection are restored, be careful about the following. - When the zero point data of absolute position detection are restored, back up them right before the restoring and use backup data. - When the motor or the detector is exchanged, the zero point data of absolute position detection cannot be restored. After exchange, set the zero point of the absolute position detector again. |
