About Confomance to Internationl Standards
EC Directives
The AC servos meet the relevant EC Directives for Low Voltage Equipment so that the
machine or equipment comprising our AC servos can meet EC Directives.
EMC Directives
MINAS Servo System conforms to relevant standard under EMC Directives setting up
certain model (condition) with certain locating distance and wiring of the servo motor and
the driver. And actual working condition often differs from this model condition especially
in wiring and grounding. Therefore, in order for the machine to conform to the EMC Di-
rectives, especially for noise emission and noise terminal voltage, it is necessary to ex-
amine the machine incorporating our servos.
Conformity to UL Standards
(1) Installation environment
Use the driver in an environment of Pollution Degree 2 prescribed in IEC60664-1.
Make sure to install a circuit breaker(MCCB) or fuse which are UL recognized on the
power supply.
Use a copper cable with temperature rating of 75 ˚C or higher.
(2) Short-Circuit Current Rating(SCCR).
This driver conform to the power source witch is less than the maximum input voltage
less than 5000 A symmetrical current.
(3) The NEC (National Electric Code).
The branch circuit of the protection NEC (National Elrctrical Code) and regional stan-
dards according to the embodiment.
(4) Over-load protection and over-temperature protection
Drivers
Over-load protective function will be activated when the effective current exceeds 115
% or more than the rated current based on the time characteristics.
Motor over-temperature protection is not provided.
Motor over-load-temperature protection shall be provided at the final installation upon
required by the NEC (National Electric Code).
