0–400Hz
Space voltage vector control, sensorless vector
control (SVC), and vector control with sensor
feedback (FVC)
Asynchronous motor (AM) and permanent magnetic
synchronous motor (SM)
For AM1: 1:200 (SVC); for SM1, 1:20 (SVC); 1:1000 (FVC)
± 0.2% (SVC); ± 0.02% (FVC)
± 0.3% (SVC)
< 20ms (SVC); < 10ms (FVC)
10% (SVC); 5% (FVC)
For AMs: 0.25Hz/150% (SVC)
For SMs: 2.5Hz/150% (SVC)
0Hz/200% (FVC)
120% for 1 minute
Settings can be implemented through digital, analog,
pulse frequency, multi-step speed running, simple
PLC, PID communication, communication and so on.
Settings can be combined and the setting channels
can be switched.
The output voltage can be kept constant although the
grid voltage changes.
More than 30 protection functions, such as protection
against overcurrent, overvoltage, undervoltage,
overtemperature, phase loss, and overload
Used to implement impact-free smooth startup for
rotating motors
Note: The function is available only for 5R5P and
higher models.
