1. Upper speed clamp - Maximum standby
seng = 250 Hz
2. Lower speed clamp - Minimum standby
speed seng = 125 Hz
3. Acve speed range - 50.00 % t
o 100.00 %
(125Hz to 250 Hz)
4. Acve Voltage range - 5.00 V to 10.00 V
1. Upper speed clamp - Maximum standby
seng = 250 Hz
2. Lower speed clamp - Minimum standby
speed seng = 125 Hz
3. Acve speed range - 50.00 % to 100.00 %
(125Hz to 250 Hz)
4. Acve Voltage range - 5.00 V to 10.00 V
Note:
0.1 V = 1% of de
fault run speed.
Voltages below 5 V will result in a clamped speed of 50% of full speed.
