9.2 Retraction function at power failure
9.2.2 Setup of Retraction Function at Power Failure System
(1) Setting the rotary switch (SW1)
Set the rotary switch (SW1) of MDS-D/DH-PFU depending on the spindle motor stop operation to be made after the
retraction is completed.
< Spindle stop operation after the retraction is completed : Deceleration and stop >
• MDS-D-PFU
Rotary switch (SW1) setting : 2 R-UNIT-7 is connected
• MDS-DH-PFU
Rotary switch (SW1) setting : 1 R-UNIT-6 is connected
< Spindle stop operation after the retraction is completed : Coast to a stop >
• MDS-D-PFU / MDS-DH-PFU
Rotary switch (SW1) setting : 0 Regenerative resistor unit is not connected
(2) Setting the dip switches (SW2, SW3)
Set the switch #1 (left-most) of the dip switch (SW2) to ON.
Sensitivity for detecting power failure can be changed using the dip switch (SW3).
CAUTION
Refer to "9.3.1 How to Set Rotary Switch and Dip Switches" for detail specifications on the rotary switch (SW1) and dip
switches (SW2, SW3) of MDS-D/DH-PFU.
