Inverters-FREQROL-A800 Plus Series　-FREQROL-A800 Plus for CRANES- Pursuit of leading drive performance

Pursuit of leading drive performance

High response

The improved speed response ensures a minimal speed fluctuation to maintain a constant speed when the load fluctuates.

• Speed response
  Real sensorless vector control 50 Hz^*3 (A700: 20 Hz)
  Vector control^*4 130 Hz^*5 (A700: 50 Hz)

High torque at low speed

Our new inverter realizes smooth cargo handling work at low speed and high torque for the slow and stable movements required for heavy objects.

• Starting torque (at 0.3 Hz)
  Real sensorless vector control 200% (ND rating)
  Vector control^*4 200% (ND rating)
  (150% of initial setting for 5.5K or higher)

• *3At 3.7 kW with no load Differs depending on the load conditions and motor capacity.
• *4The vector control is available when a vector control compatible option is installed.
• *5The option (FR-A8AP, FR-A8AL, or FR-A8TP) is required.
