Set the basic parameters.
The following parameters must be set if the drive needs to be driven by analog speed command input.
Table 8.3.2 Parameter of control mode change(Analog speed command input)
Parameter No. Parameter Description
2.0 Select control mode. Set to “1”.
3.0 Select command mode. Set to “2”.
The parameters from [48. 0] to [78. 0] in the following table can be selected according to the actual usage.
Table 8.3.3 Parameter of analog speed command input
Parameter No. Parameter Description
48.0
Analog speed command input -Filter constant
（
Numerator
）
Filter out the input command voltage
interference. Use it with parameter 62.1.
49.0 Analog speed command input -Filter constant
（
Denominator
）
50.0 Analog speed command input -Gain (Numerator) Set the speed at the maximum command
input voltage (
±
10V). (Note 1)
51.0 Analog speed command input -Gain (Denominator)
52.0 Analog speed command CCW speed limit override value
(Numerator)
Set speed limit value at CCW
rotation.(Note 2)
53.0 Analog speed command CCW speed limit override value
(Denominator)
54.0 Analog speed command CW speed limit override value
(Numerator)
Set speed limit value at CW
rotation.(Note 2)
55.0 Analog speed command CW speed limit override value
(Denominator)
60.0 Analog speed command - Fixed offset value The motor speed is 0[ r/mi n] by
adjusting the command input to 0V. Use
it with parameter 62.2.
62.0 Analog speed command - Rotational direction For details, refer to table 5.3.4.
62.1 Analog speed command - Selection of input filter Please use it with parameter 48.0 , 49.0.
62.2 Analog speed command - Selection of offset tuning method Please use it with parameter 60.0.
77.0 Speed command smoothing filter selection Please use it with parameter 78.0.
78.0 Moving average time for Speed command smoothing filter Use it when the speed of motor is not
stable. And use it with parameter 77.0.
Note 1: Set the maximum speed for the motor in parameter 51.0(Denominator). Set the expected maximum speed in
parameter 50.0(Numerator).
Example) Make the following settings if the motor with the maximum speed of 5000 [r /mi n] needs to set to 3000 [r /mi n] at the
maximum command input voltage (
±
10V).
Table 8.3.4 Analog speed command input Gain settings
Parameter No. Parameter Setting value
50.0 Analog speed command input -Gain (Numerator) “3000”
51.0 Analog speed command input -Gain (Denominator) “5000”
Note 2: Set the maximum speed for the motor in parameter 53.0, 55.0(Denominator). Set the expected speed limit value in
parameter 52.0, 54.0(Numerator).
Example) Make the following settings if the motor with the maximum speed of 5000 [r /mi n] needs to set to the maximum
speed limit value of 3000 [r /mi n].
