Sine-wave PWM method (automatic torque boost)
1.5 to 400 Hz
0.01% (--10 C to 50 C)
0.1 Hz (less than 100 Hz), 1 Hz (100 Hz or more)
0.1 Hz (operation resolution)
1 minute or less when 150% of rated output current is received
0.0 to 999 seconds (acceleration and deceleration times are
set separately)
Approximately 20%
Note 125% to 220% when braking resistor is externally
installed.
Simple V/f pattern setting
Electronic thermal protection
When 250% of the rated output amperage is exceeded
When 150% of the rated output amperage is exceeded for one
minute
approximately 410 V
R: Stops the system when voltage drops
below approximately 200 V
3G3EV-AB R: Stops the system when voltage drops
below approximately 160 V
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.
Detects a fin temperature of 110
Overcurrent level protection
