H Protection Functions
Motor protection
Electronic thermal protection
When 250% of the rated output amperage is exceeded
Instantaneous
overcurrent protection
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 approximately 820 V)
Voltage drop protection
3G3EV-A2jjj: Stops the system when voltage drops below
approximately 200 V
3G3EV-ABjjj: Stops the system when voltage drops below
approximately 160 V
3G3EV-A4jjj: Stops the system when voltage drops below
approximately 400 V
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.
Radiation fin overheat Detects a fin temperature of 110 ±10°C
