PWM Duty Cycle Description:
| Duty Cycle(%) | Description |
| 0%≤Duty＜5% | Default Output(Max Speed) |
| 5%≤Duty＜15% | PWM Mode, halt command |
| 15%≤Duty＜85% | PWM Mode, Linear Speed Regulation range |
| 85%≤Duty＜100% | PWM Mode, Speed limited(Max speed) |
| Remarks: PWM duty cycle error range:±2% PWM voltage: DC12V PWM frequency: 1KHz Notes: A: Recommended 10% duty cycle as the stop command B: Recommended 0%,95% duty cycle as default output mode (Max speed, PWM disable) | |
