• NC MD 18444 bit2 = 1 Switchover of link factor permissible
• NC MD 18444 bit3 = 1 Overwriting of synchronous positions permissible
• NC MD 18445 bit0 = 1 Axis U may be following axis
• NC MD 18445 bit1 = 1 Reconfiguration permissible
• NC MD 18435 bit2 = 1 Switchover of link factor permissible
• NC MD 18445 bit3 = 1 Overwriting of synchronous positions permissible
