●
Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
●
After the first use of the product (module, display unit, and terminal block), the number of
connections/disconnections is limited to 50 times (in accordance with IEC 61131-2). Exceeding the
limit may cause malfunction.
●
Before testing the operation, set a low speed value for the speed limit parameter so that the operation
can be stopped immediately upon occurrence of a hazardous condition.
●
Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.
CAUTION
●
When changing data and operating status, and modifying program of the running programmable
controller from an external device such as a personal computer connected to an intelligent function
module, read relevant manuals carefully and ensure the safety before operation. Incorrect change or
modification may cause system malfunction, damage to the machines, or accidents.
●
Note that when the reference axis speed is specified for interpolation operation, the speed of the
partner axis (2nd, 3rd, or 4th axis) may be faster than the set speed (may exceed the speed limit).
