Outstanding Performance of 9600 Series
9600 Series Frequency Inverter
9600 series frequency inverters are the mainstream models. Based on the customer requirement, high quality and reliability, 9600 series frequency inverters with the excellent performance and the powerful function will bring you a new experience.
Support the vector control for many motors.
  1. Support the vector control of 3P AC asynchronous motor.
  2. Support the vector control of 3P AC synchronous motor.
  3. Support the vector control of the permanent-magnet synchronous motor with absolute position feeding.
Characteristics of high start torque
9600 series frequency inverter can provide 150% of start torque at 0.5Hz (vector control without sensor) and 180% of zero-speed torque at 0Hz (vector control with sensor).
Support many encoders
Differential encoder
Open collector encoder
UVW encoder
Rotary transformer encoder
Excellent response
The torque response is < 20ms without the vector control of a sensor.
The torque response is < 5ms with the vector control of a sensor.

Novel vector control without speed sensor

The vector control without speed sensor can block the motion, and output 150% of the rating torque at 0.5Hz; The vector control without speed sensor can lower the sensitivity of the motor parameters and enhance the site adaption; The winding control can be applied for the situations where many motors drag the same load.

Protection of mechanical torque limit
9600 series frequency inverters can limit the torque. When the torque command exceeds the maximum torque that the motor can tolerate, the frequency inverters can limit the torque in the maximum setting torque to make the maximum efficiency and provide the more protection of the equipment.


Powerful Functions for 9600 Series Frequency Inverter

Virtual IO
Five sets of virtual DIDO can be set. The status of the virtual DI terminal can be directly supplied by the function code or bonded by the corresponding virtual DO.

Instantaneous non-stop

This function means the frequency inverter will not stop when the power instantaneously fails. In the circumstances of instantaneous power failure or sudden voltage drop, the frequency inverter lowers the output speed. With the energy fed by the load and the reduction of compensation voltage, the frequency inverter can continuously run in short time.

Flexible and practical simulation input/output

Each of simulation input (AI1~ AI3) can set a curve with four points individually.
AI1~ AI3 can be used to calibrate the linear curve on factory or on site, where the calibrated accuracy is 20mV;
AO can be used to calibrate the zero drift and the gain for the linear curve on factory or on site, where the calibrated accuracy is 20mV;
AI1~ AI3 can be used for DI;
AI1 has the isolated input, which can be used for PT100, PT1000 or ±10V input.

Motor over-temperature protection

The I/O expansion card can be chosen. The simulation input AI3 can accept the input from the temperature sensor (PT100, PT1000). When the motor temperature exceeds the threshold, the impulse signals from the frequency inverter will hint over-temperature. When the motor temperature exceeds the over-temperature value, the frequency inverter will output the fault to give the protection to the motor.

Quick current limit
The quick current limit can prevent the frequency inverter from frequent over-current alarm. When the current exceeds the protection point, the quick current limit can quickly limit the current within the protection point to further protect the equipment and avoid the sudden load or over-current alarm.


Multiple Motor change

Four sets of motor parameter not only can implement four motor changes, but also achieve the change between the synchronous motor and the asynchronous motor.

Guide to brake assembly
The following table is the guidance data, where a user can select the resistance and the power according to the actual conditions (The resistance must not be less than the recommended value in the table, but the power can be increased.). The brake resistor is selected according to the power generated by the motor in the actual applications, related to the system inertia, the deceleration time, the energy of potential load, depending on the customer requirements. The larger system inertia is, the shorter deceleration time is needed; the more frequent brake is applied, the larger power of the brake resistor is selected and the resistance is smaller.

Selection of resistance
During the brake, the recycling energy from the motor is almost consumed on the brake resistor.
According to the formula: U*U/ P= Pb
■ U in the formula – – – brake voltage
(depending on the system, generally take 700V for 380VAC system)
■ pb— brake power

Power selection for brake resistor
In theory, the power for the brake resistor is consistent with the brake power. However, derating is considered as 70%.
According to the formula: 0.7*Pr=Pb*D
■ Pr– resistance power
■ D— brake frequency (The recycling process shares the ratio of the whole work.)
Elevator — -20%~30%
unwind and wind —20%~30%
centrifuge —50%~60%
Sudden brake load –5%
generally take 10%

  1. The brake assemblies are used to consume some potential or energy fed from the load with larger inertia to the frequency inverter, which can avoid inverter trip owing to high voltage. They can be applied for the load with larger inertia and frequent brake or quick parking.
  2. The brake assemblies belong to peripherals. The brake unit is built in the inverter (0.75-18.5). If the brake function over 22kW is required, please order the inverter with the brake.
  3. Don’t directly connect the discharge resistor to the P or N terminal. If the inverter terminal is P or N, the discharge block must be additionally installed. If the brake assembly over 93KW is connected to the P or N terminal, please remind us before ordering.
