■ Functions
| Functions | content | |
|---|---|---|
| Operation Mode | Motor start/stop | |
| Switch running direction | ||
| Adjusting speed | ||
| Selection of three operating modes | ||
| Four-stage operating setting (speed, torque limit, acceleration/deceleration time) | ||
| Upper and lower limit settings of motor speed | ||
| Set and display the speed reduction ratio or increase ratio | ||
| Gentle start/soft stop | ||
| Simple stop and hold mode | ||
| Speed setting method | Use the knob to adjust the speed | |
| Use I/O to set the speed of four-stage running data | ||
| Acceleration time, deceleration time* |
Analog Setting: Set by acceleration and deceleration knob. Set within the range of 0.2~15 seconds. | |
| Digital Setting: Set the number of each segment of the operating data. Set within the range of 0.2~15 seconds. | ||
| *1 Actual acceleration time and deceleration time are affected by the customer's usage conditions, load inertia, load torque, etc. | ||
| Input signal | Optocoupler input method: power supply must be less than 10mA | |
| Operation using internal power supply: DC5V | ||
| Connectable external DC power supply: DC5~30V | ||
| SINK input/SOURCE input | ||
| Three groups of inputs (X0~X2) can be assigned to signals. Factory settings: [FWD], [REV], [M0] | ||
| Output signal | Optocoupler, transistor open collector circuit output | |
| External DC power supply: DC5~30V | ||
| SINK output/SOURCE output | ||
| Two sets of outputs (Y0~Y1) can be assigned to the signal. Factory setting: [SPEED OUT], [ALARM OUT] | ||
| Protection function | Abnormal alarm display, overload, overcurrent, overvoltage, undervoltage, overspeed, motor stall, detector abnormality, safe start, driver overtemperature, driver power module abnormality. | |
■ Multi-stage speed operation
While using multi-stage speed, switch between M0, M1 and input to perform multi-stage operation.
Example:
| Operation data | M0 | M1 | Speed |
|---|---|---|---|
| No.1 | OFF | OFF | 3000 |
| No.2 | ON | OFF | 2000 |
| No.3 | OFF | ON | 1000 |
| No.4 | ON | ON | 500 |
Note: Please refer to the BU series operation manual for relevant details.
