5.1 Before Powering On
WARNING:
Follow Lockout/Tagout and other safety precautions when connecting and 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. Confirm PLC connection (4.7 and 4.8)
P Verify that the ISA Main Unit and Axis Unit PLC wiring is connected to the
corresponding PLC terminals.
2. Check connections between the tool and the Axis Unit (3.2.4, 3.2.5, 3.2.6, and 4.9.4)
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.
3. Confirm connection of communication cables (4.9.3)
P Verify that the communication bus ribbon cable is connected from the ISA Main Unit
to the nearest Axis Unit.
P Verify that all Axis Units are connected (daisy-chained) with the ribbon cable(s).
4. Verify Axis Unit dip switch settings (4.9.1 and 4.9.2)
P Verify the five (5) dip switches visible on the left side of each Unit are set to indicate
the appropriate spindle number.
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.)
5. Confirm connection of Keyboard/Keypad cable (3.2.1 and 3.2.3)
P Confirm that the keyboard/keypad cable has been connected to the front of the ISA
Main Unit.
6. Confirm connection of Monitor/VGA CRT cable (3.2.2, 3.2.3 and 4.6.1)
P Confirm that the monitor (CRT) cable is correctly connected to the ISA Main Unit.
P Ensure that the CRT power switch is in the "on" position.
7. Check the input voltage (3.2.3, 3.2.4, 4.6, and 4.8)
P Verify input power is connected in accordance with the instructions in Chapter 4.
P Ensure input power voltage to the ISA Main Unit and the Axis Units is 200~230 VAC.
P Ensure proper input power voltage to the Monitor/VGA CRT.
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, turn the power off for five (5) minutes before making another
attempt to power up.
