(8) Performing EMC tests
When EMC tests are run on a machine/device into which the servo amplifier has been installed, it
must conform to the electromagnetic compatibility (immunity/emission) standards after it has
satisfied the operating environment/electrical equipment specifications.
For the other EMC directive guidelines on the servo amplifier, refer to the EMC Installation
Guidelines(IB(NA)67310).
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-J2S-10B-PY096 to MR-J2S-350B-PY096
MR-J2S-500B-S096 to MR-J2S-700B-S096
MR-J2S-10B1-PY096 to MR-J2S-40B1-PY096
Servo motor :HC-KFS
HC-MFS
HC-SFS
HC-RFS
HC-UFS
HA-LFS
HC-LFS
(2) Installation
Install a cooling fan of 100CFM (2.8m
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
This servo amplifier conforms to the circuit whose peak current is limited to 5000A 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.
Servo amplifier
Discharge time
[min]
MR-J2S-10B(1) 20B(1) 1
MR-J2S-40B(1) 60B 2
MR-J2S-70B to 350B 3
MR-J2S-500B 700B 5
MR-J2S-11KB 4
MR-J2S-15KB 6
MR-J2S-22KB 8
(5) Options and auxiliary equipment
Use UL/C-UL standard-compliant products.
