Figure 10 Analogue speed control
1. Upper speed clamp: Maximum standby
speed setting = 30 Hz
2. Lower speed clamp: Minimum standby
speed setting = 20 Hz
3. Active speed range: 66.66% to 100% (20
Hz to 30 Hz)
4. Active voltage range: 6.66 V to 10 V
Note:
Voltages below 6.7 V will result in a
clamped speed of 67% of full speed.
