Straight-line Type V/F Curve VFD Three Phase 380V-480V Built-in C3 Filter LED Keyboard OLVC Control Mode

   Performance characteristic   

   Specialization characteristic   

• Anti-roll control, inhibit spreader swing, efficient operation
• Speed with load, the operating speed can be adjusted in real time according to the equipment load changes
• Hook protection, brake detection hook, control motor output hover
• Easy positioning through the combination of deceleration and stop limits
• Anti-loose rope protection, up at a fixed speed, to detect lifting heavy objects, slowly accelerate, rise steadily
• The lifting mechanism can be selected according to the lifting parameter macro setting value
• Multi-motor switching, internal support 4 sets of motor parameters

   High reliability   

• The whole machine independent air duct design, effectively prevent dust impurities into
• Efficient and accurate thermal simulation platform software
• Advanced thermal testing and verification technology and equipment to effectively verify the theoretical results of thermal            design
• Rigorous full load and overload verification test procedures
• The products are aging after high temperature belt load, effectively guarantee the factory quality
• Circuit board protection enhanced design, anti-corrosion, moisture-proof, dust and so on

   High adaptability   

• Wide voltage range design, three-phase 380V~480V (-15%~+10%)
• Built-in C3 filter to effectively suppress high-frequency harmonics generated by the inverter
• Simple and friendly EMC ground break design can effectively reduce the current to the floor drain
• Book type design, the volume is reduced by about 40% compared to traditional models
• Can realize the whole machine side by side installation, saving installation space

   Performance control optimization   

• Support the drive control of three-phase asynchronous motor and permanent magnet synchronous motor
• Support V/F control, open loop vector control, closed loop vector control
• Large starting torque, OLVC: 0.5Hz/150%, CLVC: 0Hz/200%
• High overload capacity, 150% rated current 60s, 180% rated current 10s

   Easy to use   

• 132kW and above standard machine factory configuration LED keyboard can support external import
• Keyboards 110kW and below can be equipped with a separate LED keyboard
• When the inverter starts and stops, the motor can be controlled by holding the brake
• Multi-segment speed control function, through the control terminal to achieve 16 segment speed operation
• Zero servo function, CLVC mode can achieve zero speed motor position locking
• Random PWM depth can improve the harsh noise of the motor
• Encoder redundancy operation mode, encoder failure can automatically switch to OLVC operation

   Expansion and diversification   

• Supports multiple code disk interface cards
• Supports I/O terminal expansion cards
• Support Profibus-DP, Profinet IO, CANopen, Modbus-TCP/IP, EtherNet IP, Ethercat and other communication

   Autonomous fast debugging   

• Support to connect background software, making debugging and maintenance more convenient
• Support event recording and fault recording
