14.3 Motion Control
14-95
• MD21310 COUPLING_MODE_1
Meaning: Spindle synchronicity mode
Setting value: 0---actual value coupling: Slave axis synchronizes with the master axis
position feedback value
1---setpoint coupling: The salve axis synchronizes with the master axis
position reference value.
2---speed coupling: Speed synchronization control
(normally not used since the position control is not executed in this
mode)
• MD21320 COUPLING_BLOCK_CHANGE_CTRL_1
Meaning: Block changing mode during synchronicity
Setting value: 0---immediately change
1---change when ’Fine synchronism’ tolerance MD37210 is initiated
2---change when ’coarse synchronism’ tolerance MD37200 is initiated
• MD21330 COUPLING_RESET_MODE_1
Meaning: Synchronicity setting when rest
• MD21340 COUPLING_IS_WRITE_PROT_1
Meaning: Synchronicity conditions modifying setting
Setting value: 0---adjustable with CNC program
1---not adjustable with CNC program
• MD37200 COUPLE_POS_TOL_COARSE
Meaning: ’Coarse synchronism’ tolerance range
Setting value: [mm] or [deg]
• MD37210 COUPLE_POS_TOL_FINE
Meaning: ’Fine synchronism’ tolerance range
Setting value: [mm] or [deg]
• SD42300 COUPLE_RATIO [0]
Meaning: Numerator for synchronicity speed ratio
• MD42300 COUPLE_RATIO [1]
Meaning: Denominator for synchronicity speed ratio
Setting value: Sets synchronicity speed ratio for spindle/following axis synchronizing
with spindle
Speed ratio = SD42300[0]/SD42300[1]
Settable with CNC program.
