タイトルまたは説明

PI***0 series frequency inverter is the high-end inverter of POWTRAN. It concludes below improvement & invovation based on the ordinary V/ F inverter. With the high-end design and high quality and reliability, PI***0 series inverter will bring the users all new experience.
The perfect performances are as below:
1. Support for multi-motor vector control ( three-phase AC synchronous motor, three-phase AC induction motor, permanent magnet servo motor)
2 Supports a variety of encoder
Differential encoder - synchronous motor, induction motor are supported
Open collector encoder - synchronous motor, induction motor support
UVW encoder
Resolver encoder - synchronous motors, induction motors are supported by
Cosine encoder
3. To protect the mechanical torque limitation
This inverter can provide the torque limit, when torque command exceeds the maximum mechanical torque, the inverter will limit the torque to the maximum torque set , To protect the equipment safety in case of play the maximum mechanical efficiency.
4. High starting torque feature.
**0% of starting torque at 0.5HZ, **0% of the zero speed torque at 0HZ( sensorless vector control)
5. Superior responsiveness
Sensorless vector control, the torque corresponding < *0ms, sensor vector control, the torque response < 5ms
6. Motor overheating protection
Selection of and output expansion card, analog AI3 can accpet motor temperature sensor ( PT**0, PT***0, ) when the motor temperature exceeds the alarm value, the inverter output pulse signal, suggesting overheating, when the motor temperature exceeds the overtemperature protection, inverter failure output gives motor properly protected
7. Prompt current limit function
Prompt current limit feature allows the inverter to avoid frequent overcurrent alarm, when the current exceeds the current protection, current is promptly limited under the protection point, to protect the safety of the equipment to avoid interference due to suddenly applied load or caused by the over-current alarm.
8. Multi-motor switch
Have the set of motor parameters, to achieve the four-motor switch, the switching of the synchronous motor and induction motor.
9.Inverter non-stop while Instantaneous electricity failure
Inverter will not stop while Instantaneous power failure or voltage is suddenly reduced, the inverter reduces the output speed by load feedback energy, lower offset voltage, in order to maintain the inverter continues to run within a short time.
*0. Virtual IO functionality
Can set 5 groups of virtual DIDO, virtual DI terminal state can be directly given by the function code, or bind to the corresponding virtual DO function.
*1. Flexibility use of analog and output
Each analog s ( AI1 to AI3) , users can set the four points of the curve, use more flexiblely
*2.Rich scalability
User programmable control card, PG card, RS**5 communication card
Powerful back-end software functionality
Ease of use
Restore the user parameters
*3 Support a variety of communication.
RS**5
PROFIBUS-DP
CANLINK
CANOPEN
*4. 7.5KW more than standard DC reactor is built-in for inverters over 7.5KW
Resistance to environmental design
( 1) moisture and dust and anti-fungal anti-paint treatment process
( 2) Wide voltage range design
( 3) full range of independent duct design
( 4) comply with ROHS standards
*5. Fans are easy to install
Integrated multi-industry, non-standard, more powerful
Multi-level menu functions
