||||
| Setting resolution | 0.005% of max. speed | ||||
| Control | Operation method | KEYPAD operation: FWD or REV key, STOP key Digital input signal operation: FWD or REV command, Coast-to-stop command, reset input, multistep speed selection command, etc. |
|||
| Speed setting | KEYPAD operation:  or  keyExternal potentiometer: three terminals, 1 to 5k Analog input: 0 to 10V UP/DOWN control: Speed increases when UP signal (DI) is ON, and decreases when DOWN signal (DI) is ON. Multistep speed: Up to 15 different speeds can be selected by combining four external input signals (DI). Digital signal: Setting with an option card's 16-bit parallel signal Serial link operation: RS-485 (standard). Setting through different communication options is possible. Jogging operation:  or  key, FWD or REV terminals in jogging mode |
||||
| Running status signal | Transistor output: Inverter running, Speed equivalence, Speed detection, inverter overload early warning, torque limiting, etc. Analog output: Motor speed, Output voltage, Torque, Load factor, etc. |
||||
| Acceleration/Deceleration time | 0.01 to 3600s (4 independent settings for acceleration and deceleration selectable with external signals) (S-curve acceleration/deceleration in addition to linear acceleration/deceleration) |
||||
| Gain for speed setting | Sets the proportional relationship between analog speed setting and motor speed in the range of 0 to 200%. | ||||
| Jump speed | Jump speed (3 points) and jump hysteresis width (1 point) can be set. | ||||
| Rotating motor pick up (Flying start) | A rotating motor can be smoothly picked up by the inverter without stopping. (Vector control and sensorless vector control) | ||||
| Auto-restart after momentary power failure | Automatic restart is available without stopping the motor after a momentary power failure. | ||||
| Slip compensation | Compensates for the decrease of speed due to load and realizes stable operation (V/f control). | ||||
| Droop control | The motor speed droops in proportion to output torque. | ||||
| Torque limiting | Limits the torque to predetermined values (selectable from "common to 4 quadrants", "independent driving and braking", etc.) Analog and external signal (2 steps) settings are available (vector control and sensorless vector control). |
||||
| PID control | PID control with analog input | ||||
| Fan stop operation | Stops the cooling fan at low temperatures to reduce noise. | ||||
| Torque bias | Can be set using a fixed value (1 step, with polarity change in accord with motor rotating direction), internal setting (3 steps) by combination of external signals (DI signals), and analog setting (with holding function). |
||||
| Speed limiting |
Same limit to FWD/REV rotation, upper and lower limits, and individual limits to FWD/REV rotation. Speed limit usable even in torque control mode. |
||||
| Motor selection | Select from three types. | ||||
| Multiple winding motor drive | Optional | ||||
| UP/DOWN control | Speed can be set with external signals (DI signals); combination of UP command, DOWN command, and zero clear command. | ||||
| Stopping function | Three types of stopping functions, STOP 1, 2 and 3 | ||||
| PG pulse output | Divides PG signal for output. | ||||
| Observer | Suppresses load disturbances and vibrations. | ||||
| Position control | Optional | ||||
| Synchronized operation | Optional | ||||
