Protection Functions
Motor protection Electronic thermal protection
Instantaneous overcurrent
protection When 250% of the rated output amperage is exceeded
Overload protection When 150% of the rated output amperage is exceeded for one minute
Overvoltage protection Stops the system when DC voltage of the main circuit exceeds
approximately 410 V (400-VAC class: 820 V)
Voltage drop protection 3G3EV-A2
j
: Stops the system when voltage drops below approximately
200 VDC
3G3EV-AB
j
: Stops the system when voltage drops below approximately
160 VDC
3G3EV-A4
j
: Stops the system when voltage drops below approximately
400 VDC
Protection from
instantaneous power
interruption Stops the system when a power interruption lasts for 15 ms or more.
Operation can be continued by setting constant No. 36 as follows:
•
Operation is continued if a power interruption only lasts for approximately 0.5
second or less.
•
Operation is continued unconditionally.
