OMRON Sysdrive 3G3HV - Detector Cooling Section

• Two acceleration times and two deceleration times can be set with the
Inverter, any of which can be selected with remote output.
V/f Settings
• Select a V/f pattern out of the 15 V/f patterns preset with the Inverter
according to the application.
• An optional V/f pattern can be set with the Inverter.
Monitor Function
• The following items can be monitored with the Digital Operator.
Frequency reference, output frequency, output current, output voltage, DC voltage, output
power, status of input terminals, inverter status, power interruption error, PROM number,
total operating time, and PID feedback value
Low Noise (3.7- to 160-kW Models)
• The output transistor of the Inverter is an IGBT (insulated gate bipolar
transistor). Using a sine-wave PWM method with a high-frequency
carrier, the motor does not generate metallic noise.
High Torque at Low Output Frequency Range
• A torque rate of 150% can be achieved even in a low speed range
where output frequency is only 3 Hz.
Automatic Torque Boost
• The Inverter automatically adjusts the output according to the required
torque of the motor that is rotating at constant or accelerative speed,
thus ensuring the powerful rotation of the motor.
Harmonic Countermeasures (3.7- to 160-kW Models)
• DC reactors (optional) can be connected to 3.7- to 15-kW models.
• Models of 18.5- to 160-kW have a built-in DC reactor and also employ
12-pulse rectification, which suppresses harmonics better than a
reactor.
