Product Specification of Variable Torque Load Inverters
- Bias:Bias of set frequency and PID command can be set in the range between 0 and ±100%
- Control Method:V/f control
- Cooling Fans:(ON/OFF control) Detects inverter internal temperature and stops cooling fan when the temperature is low.
- Current Limit:Keeps the current under the preset value during operation.
- Energy saving operation:The output voltage is controlled to minimize the total sum of the motor loss and inverter loss at a constant speed.
- Frequency limiter:High and low limiters can be set (setting range: 0 to 120Hz)
- Frequency setting signal:Maximum frequency: 25 to 120Hz
Base frequency: 25 to 120Hz
Carrier frequency: 0.75 to 15kHz (200V/400V: 0.75 to 22kW)
0.75 to 10kHz (200V/400V: 30 to 75kW)
0.75 to 6kHz (200V/400V: 90 to 500kW)
- Gain Range:The analog input gain can be set in the range from 0 to 200%.(Frequency Setting)
- Jump frequency control:Three operation points and the jump width (0 to 30Hz) common to the three points can be set.
- Stability:Analog setting: Less than ±0.2% of maximum frequency (at 25±10°C)
Keypad setting: Less than ±0.01% of maximum frequency (at -10 to +50°C)
- Starting Torque:50% or over
