turned OFF, terminal [2] function C002 and terminal [1] function C001 will remain
as NO (no function assigned) and [RS] (code 18), respectively.
Note 4: Function [EMR] (code 64) cannot be assigned to input terminal 3 by an operation
from the digital operator. The function is automatically assigned to the terminal when
slide switch SW1 is set to ON.
Note 5: After slide switch SW1 has been set to ON once, function assignments to intelligent
input terminals [1] and [3] are not returned to their original assignments. If necessary,
reassign original functions to the intelligent input terminals.
Note that data from an inverter configured for the emergency stop function can affect copy
operations when using an optional operator (SRW or SRW-EX).
If operator data is copied to a SJ700 series inverter that has slide switch SW1 in the ON
position from another SJ700 series inverter whose slide switch SW1 is OFF or an SJ300 series
inverter, the digital operator on your SJ700 series inverter may display [R-ERROR COPY
ROM] for a moment. This event may occur because the data on intelligent input terminals [1]
and [3] cannot be copied since, on your inverter, exclusive functions have already been
assigned to intelligent input terminals [1] and [3] due to the slide switch SW1 setting to ON.
Note that other data is copied. If this event occurs, check the settings on both copy-source and
copy-destination inverters.
NOTE: To use the copied data in inverter operation, power OFF and ON again after the copy
operation is complete.
The following Safety Categories are defined by EN954-1 (JIS B 9705).
Safety requirement
Components, safety-related parts of control
system, and protective equipment must be
designed, manufactured, selected, assembled,
and combined in accordance with related
standards to ensure resistance to the anticipated
adverse effects of faults.
The requirements of Category B must be
applied. Proven components and safety
principles must be applied.
The requirements of Category B and proven
safety principle specifications must be applied.
The safety function must be checked by the
machine control system at appropriate inter-
vals. The requirements of category B and
proven safety principle specifications must be
applied. Safety-related parts must be designed
to meet the following requirements:
• Any single defect (fault) in a part must not
cause any loss of the safety functions.
• If a single defect (fault) occurs, it must
always be detected when the safety function
can be reasonably implemented.
System behavior
A defect (fault) may cause a loss
of the safety function.
A defect (fault) may cause a loss
of the safety function. However,
the probability of loss is less than
that specified for Category B.
• A defect (fault) occurring
during checking may cause a
loss of the safety function.
• A loss of the safety function is
detected by checking.
