SRV-63 series AC servo drives Detailed parameter description
-121-
For example, after analog input 1 command terminal of the drive is connected with analog
reference signal, then even if the analog reference signal is 0, the voltage value of analog input 1
(R1.05) displayed by the panel will be 0.02V, P3.20 should be set to 0.02 at this time. The drive
will automatically subtract 0.02V from the analog input value received. If the analog input 2
voltage displayed by the panel is -0.02V, then parameter P3.20 should be set to -0.02. The drive
will automatically add 0.02V to the analog input value received and the value displayed by the
panel will change at the same time.

This parameter is used to set the time constant of the first order low-pass filter corresponds to
analog input 1. Setting this parameter can smooth the command changing when the analog input
changes violently. Please refer to the figure below:

S
This parameter is used to set the overvoltage protection of analog input 1.
If the absolute value of R1.05 exceeds the setting value, the system will report fault.
Note:
1. The default value 0 means no overvoltage protection;
2. The input voltage should be no more than 10V, otherwise damage may occur to the drive.

This parameter can be used to adjust the analog input 2 to improve the effective accuracy of
analog input.
The setting method is the same with P3.20.
