variable frequency inverter Description
The SVD-P series AC drive is a general-purpose high-performance current vector control AC drive. It is an upgrade product based on SVD-E and can implement the control of asynchronous motor and permanent magnet synchronous motor (PMSM). It increases the user programmable function, background monitoring software and communication bus function, and supports multi-kind PG cards. It is used to drive various automation production equipment involving textile, paper-making, wiredrawing, machine tool, packing, food, fan and pump.

The newly added functions of the SVD-P series AC drive are
described as below:
| Function | Description |
| Virtual I/O | It can implement various simple logic functions. |
Motor overheat protection | The optional SP-IO1 extension card enables AI3 to receive the signal from the motor temperature sensor input (PT100, PT1000) thereby providing motor overheat protection. |
Rapid current limit | It helps to avoid frequent occurrence of overcurrent faults of the AC drive. |
Multi-motor switchover | Four motors can be switched over via four groups of motor parameters. |
Restoring user parameters | It allows you to save or restore the parameters set by yourself. |
Higher-accuracy AI/AO | The AI/AO accuracy can reach almost 20 mv via factory correction or on-site correction. |
| Customized parameter display | You can customize the parameters that need to be displayed. |
| Modified parameter display | You can view the modified parameters. |
Operation selection at fault occurrence | You can select the reaction of the AC drive to a fault occurring, based on the actual need. The reactions are as below: • Coast to stop • Decelerate to stop • Continue to run You can also select the frequency at which the AC drive continues to run. |
PID parameters switchover | Two groups of PID parameters can be switched over via terminals or can be automatically switched over according to deviation. |
PID feedback loss detection | The PID feedback loss value can be set to realize PID protection. |
| DI/DO positive or negative logic |
You can set the DI/DO positive or negative logic. |
| DI/DO response delay | You can set DI/DO response delay time. |
Power dip ride through | It ensures that the AC drive continues to run for a short time when an instantaneous power failure or sudden voltage reduction occurs. |
Timing operation | The AC drive supports timing operation for 6500 minutes at maximum. |
User programmable function | The externally connected programmable card helps you to realize secondary development. |
Load allocation | Load allocation can be implemented between two SVD-P series AC drives through point-to-point communication. |
