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.
WARNING:
Damage may occur if the 24 VDC and 0 VDC Commons are improperly con-
nected.
1. Verify San Unit DIP switch settings (4.10)
P
Verify that the eight (8) DIP switches visible on the front of each unit are set to indicate the appro-
priate spindle number and options.
2. Confirm Interface (PLC) connection (4.7)
P
Verify that the San unit I/O Interface wiring is connected to the corresponding PLC terminals.
3. Check connections between the tool and the San unit (3.2)
P
Verify that the two (2) homerun cables (resolver/ motor and transducer) connecting the tool and
San unit are secure. Ensure that each numbered set of two (2) cables is connected to the identically-
numbered tool and San 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.
WARNING:
Do not make motor connections with the power on. Turn off all controller power
before attempting to connect or disconnect any motor cables or tool damage may occur.
4. Check the input voltage (3.2, 4.6)
P
Verify input power is properly connected (4.11.2).
P
Ensure input power voltage to the San Units is 200~242 VAC.
P
After turning on the power, verify the voltage again to ensure it has not dropped as a result of load-
ing.
NOTE: After a SAN 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 SAN unit. If a
SAN unit does become disabled, keep the power off for five (5) minutes, then power on again
to reset the fault.
