Grounding
All equipment and components of a machine or process system shall have
their chassis connected to a common earth ground point. This ground
system provides a low impedance path that helps minimize shock hazards
to personnel and damage to equipment caused by short circuits, transient
overvoltages and accidental connection of energized conductors to the
equipment chassis.
Grounding requirements, conventions and definitions are contained in the
National Electrical Code or appropriate national codes. Local codes will
usually dictate what particular rules and regulations are to be followed
concerning system safety grounds.
Wiring Clearance and Routing
Although the minimum clearance should be maintained for proper cooling,
this space may not always provide proper wiring clearance. The minimum
allowable wire bending radius may necessitate that extra space be provided
to accommodate power wiring. Consult the National Electrical Code or the
appropriate national or local code for the proper wiring method.
Signal Wiring
The 8510 inputs and outputs are all rated for +24V DC. The +24V DC
voltage source must be supplied by the user. Each input that is used
requires about 10mA of input current and all outputs are physical contact
closures.
All signal connections are made through MR series Honda connectors. The
mating connectors required for signal interfaces are as follows:
Function Number Honda Type
Standard I/O (Always Required) CN9 MR-50LF
Motor Resolver Feedback (Always Required) CN3 MR-20LF
Digital Position/Speed Input (Optional) CN10 MR-20LF
Spindle Orient Feedback (Optional) CN2 MR-20LF
Dual Winding Motor Control (Optional) CN1 MR-20LF
Three termination options are available for each of the connectors.
l) A mating connector kit that requires the user to supply the cable and
terminate directly to the Honda connector. This is a solder type
connector. A crimp connector, the MRP series, is available from the
manufacturer.
2) A termination panel that provides a prefabricated 1.5 m (5 ft.) cable
from the drive connector to a DIN rail mounted terminal block
interface module. User wiring is to the terminal block.
3) A cable assembly in varying lengths with the Honda connector wired to
one end. The other end is loose cable leads for user termination as
required.
