3. Backup Base Sensor Position
Chapter 6 Backup Base Section
3.1 Backup U/D and Lower Limit Detection
Confirm with a photosensor checker and a dial gauge that the backup U/D and lower limit
detection sensor is changed to "E/R" (Light Emitted and Received) mode from "E/NR"
(Light Emitted and Not Received) mode at the position where the backup base has
ascended by 1.0±0.2 mm after the brake was released, the backup base was moved down,
and the base touched the stopper.
• When "E/NR" is not changed to
"E/R" at the position, make the
adjustment with Pin 10.
After the setting of the lower limit
detection, confirm that Phase C can be
detected in the range where the backup
base ascends 1.8 to 2.2 mm from the
position where the lower limit
detection sensor is turned "ON".
3.2 Setting of Protective Stopper for Backup Base Detection Sensor
(1) Attach Backup Base Detection
Sensor S26 to the backup base.
(Small Pan-Head Screw M3L10)
(2) Loosen the M3 nuts and adjust the
height of the stopper bolts (M3L16)
so that the dimension between the
bolt mounting face and the bolt
head can be "14.5±0.2 mm" as
shown in Fig. F11.

4. Backup Base Offsets
Chapter 6 Backup Base Section
4.1 Backup Base Offsets
• Clearance after Upward Movement (48.5 mm) of Base from Origin Position: 44 mm
(Design Value)
• Measuring Spots: Position of "Conveyor Width = 300 mm", 4 places for each base
Offset Values Entered (Example)
Minus
Upper Surface of PCB
Plus
Actually Measured Value 43.95 ----- Offset +0.05
Actually Measured Value 44.05 ----- Offset -0.05
Manual Alignment Operation
(1) Follow the operation sequence ([MAINT] Button → [DVC CHECK] Button →
[MOTOR] Button → [Block5] (Others) Button → [NA-LL1] or [NC-LR1] Button).
Movement by Relative Value: Travel 44 mm
Confirm that there is no support pin on the backup base.
(2) Select the [-] button and press the [start] button.
Entry Destination (Machine Side)
Enter parameters in the "B1 [mm]" text boxes of the labels "NA" and "NC" in the
"Device Ofst" subtab sheet. (Operation Sequence: [MACH SET] Button → [MACH.
SYS.] Button → "System" Window → "Device Offset" Tab Sheet → "Device Ofst"
