5.1 Before Powering On
WARNING: Follow Lockout/Tagout and other safety precautions when connecting or
disconnecting cabling, wiring, and equipment.
Each item below lists the manual Section(s) that will provide a reference for that specific item.
Also refer to Section 3.1 System Block Diagram and Section 4.5 Wiring Diagram.
CAUTION: Damage may occur if the 24 VDC and 0 VDC Commons are improperly connected.
1. Verify Axis Unit dip switch settings (4.10.1 and 4.10.2)
P Verify that the eight (8) dip switches visible on the left side of each unit are set to
indicate the appropriate spindle number and options.
P Verify the Ramp-Up Speed dip switches are set to the appropriate length of time for
each Axis unit. (Axis Units with a model number ending with "A" are preset at the
factory to 250 milliseconds. The Axis unit cover must be removed to access the dip
switches.)
2. Confirm PLC connection (4.7)
P Verify that the Axis unit PLC wiring is connected to the corresponding PLC terminals.
3. Check connections between the tool and the Axis unit (3.2.1)
P Verify that the three (3) homerun cables (encoder, motor, and transducer/sensor)
connecting the tool and Axis unit are secure. Ensure that each numbered set of three
(3) cables is connected to the identically-numbered tool and Axis unit.
P If the layout contains moveable parts, visually inspect all components to ensure that
there is proper clearance and that cables have sufficient length. If movement would
create any excessive stress on a cable, or create any potential for damage to the
System or other components in the layout, then make appropriate adjustments.
4. Check the input voltage (3.2.1, 4.6)
P Verify input power is connected in accordance with the instructions in Chapter 4.
P Ensure input power voltage to the Axis Units is 200~230 VAC.
P After turning on the power, verify the voltage again to ensure it has not dropped as a
result of loading.
NOTE: After an Axis unit is powered down, the power must not be applied again for at least five (5)
seconds. Repeated power up and power down may temporarily disable the Axis unit. If an
Axis unit does become disabled, keep the power off for five (5) minutes, then power on again.
