(6) Usage
CAUTION
Use this product within the range of environmental condition described in this manual.
Using this product in an environment outside the range could result in electric shock, fire, operation failure,
or damage to or deterioration of the product.
Install an external emergency stop circuit so that the operation can be stopped and the power turns OFF
immediately when unforeseen situation occurs. A contactor, etc., is required in addition to the shutoff
function mounted in the controller.
Turn OFF the power immediately if any smoke, abnormal noise or odor is generated from the controller,
drive unit or motor.
Only a qualified technician may disassemble or repair this product.
Do not alter.
Use a noise filter, etc. to reduce the effect of electromagnetic disturbances in the case where
electromagnetic disturbances could adversely affect the electronic devices used near the drive unit.
Use the drive unit, motor and each regenerative resistor with the designated combination. Failure to
observe this could result in fires or faults.
The combination of the motor and drive unit that can be used is determined. Be sure to check the models
of motor and drive unit before test operation.
The brakes (electromagnetic brakes) mounted in the servomotor are used for the purpose of holding, and
must not be used for normal braking. Also, do not run the motor with the motor brake applied. Motor brake
is used for the purpose of holding.
For the system running via a timing belt, install a brake on the machine side so that safety can be ensured.
Be sure to confirm SERVO OFF (or READY OFF) when applying the electromagnetic brake. Also, be sure
to confirm SERVO ON prior to releasing the brake.
When using the DC OFF type electromagnetic brake, be sure to install a surge absorber on the brake
terminal.
Do not connect or disconnect the cannon plug while the electromagnetic brake’s power is ON. The cannon
plug pins could be damaged by sparks.
After changing programs/parameters, or after maintenance/inspection, always carry out a test operation
before starting actual operation.
Use the power that are complied with the power specification conditions (input voltage, input frequency,
tolerable instantaneous power failure time) indicated in each specifications manual.
When making detector cables, do not mistake connection. Failure to observe this could result in
malfunction, runaway or fire.
Surge absorber to be selected varies depending on input power voltage.
