CONFORMANCE WITH UL/C-UL STANDARD
(1) Servo amplifiers and servo motors used
Use the servo amplifiers and servo motors which comply with the standard model.
Servo amplifier :MR-E-10A-QW003 to MR-E-200A-QW003
MR-E-10AG-QW003 to MR-E-200AG-QW003
Servo motor :HF-KE
W1-S100
HF-SE
JW1-S100
(2) Installation
Install a cooling fan of 100CFM (2.8 m
3
/min) air flow 4 in (10.16 cm) above the servo amplifier or provide
cooling of at least equivalent capability.
(3) Short circuit rating: SCCR (Short Circuit Current Rating)
This servo amplifier conforms to the circuit whose peak current is limited to 100kA or less. Having been
subjected to the short-circuit tests of the UL in the alternating-current circuit, the servo amplifier conforms to
the above circuit.
(4) Capacitor discharge time
The capacitor discharge time is as listed below. To ensure safety, do not touch the charging section for 15
minutes after power-off.
