Safety precaution in wiring
(continued)
Danger
(29)
When inserting the electric wire into a metal duct etc., the allowable electric current of the
electric wire is lowered due to the temperature rise, so the electric wire is selected after
studying the current reduction coefficient.
(30)
Wiring has to be carried out by the qualified and authorised specialist.
(31)
Connect cables reliably. Insulate the conductive part with an insulator. And fix the cable so
that any stress is not applied to the connection part such as the connector or terminal block.
(32)
Conductive material such as electric wire scraps should not get inside the product.
(33)
Turn off the power when wiring or disconnecting wiring.
Caution
(34)
Commercial power supply should be used for power supply of brushless amplifier.
(35)
When connecting the grounding terminal of the extension cable, use a terminal block or an
insulation sleeve for insulation.
Safety precautions during operation
Danger
(36)
Do not touch the brushless amplifier or brushless motor as it will be hot.
(37)
Do not set very high velocity loop gain, and do not change the velocity loop gain signifi-
cantly.
(38)
Do not touch the rotating part of the brushless motor during operation.
(39)
Do not operate with wet hands.
(40)
While energizing, pay attention to unintentional restart during stop.
(41)
Turn on and turn off the power after the worker themselves confirms the safety of the sur-
roundings.
(42)
Turn off the power when touching the motor connector.
Caution
(43)
Do not constrain the output shaft of the motor.
(44)
Do not start / stop the brushless motor frequently using the electromagnetic contactor in-
stalled on the main power supply side.
