be configured on the host computer .
Output voltage corresponding
to the speed (rpm)
n 1 ( Configured on the host
computer )
n 2 ( Configuration on the host
computer )
Calculation formula:
If the driver ANOUT outputs a voltage of X, the output speed n of the motor under this voltage is :
n output
/speed can be controlled by inputting 0.5V-4V voltage to the ANIN port .
the driver output duty cycle range when ANIN is input at 0.5-4V on the host computer
software . The output range is adjustable but must meet the 0-98% range.
Selecting the closed loop mode allows the host computer software to configure the output
speed of the drive when ANIN is 0.5-4V .
Open loop mode output duty
cycle
D1 (host computer
configuration, minimum 0 )
D2 (host computer
configuration, maximum 98 )
Closed loop mode output
speed rpm
n1 (Upper computer
configuration )
n2 (Upper computer
configuration )
Calculation formula in open loop mode:
1. Input a voltage of value X to the ANIN port , and calculate the driver duty cycle D output as :
D output
2. If the driver outputs a duty cycle of D%, the voltage X that should be input to ANIN should be :
X
the external input voltage is less than 0.5V or is left floating , the driver output duty cycle is D1%
When the external input voltage is >4.0V, the driver output duty cycle is D2%
Calculation formula in closed loop mode:
1. Input a voltage of value X to the A NIN port, and the output of the driver speed n can be
