0
[ - ]
Function
Use
Set the offset value when Analog velocity: offset tuning method (No.62.2) = 1 (manual).
Connect power for the analog command, having the input voltage of 0 V, and adjust this parameter
such that the rotational speed becomes 0 r/min.
1. For CCW rotations, set this parameter to a negative number, and for CW rotations, set to
a positive number.
2. If the actual rotational speed is beyond the ± 10 r/min range, set this parameter to ± 50 and
check the motor motions.
Prerequisite Analog velocity: Offset tuning method (No.62.2) = 1 (manual)

Function
Use
Enable/Disable Input filter for Analog Velocity Command.
This filter is a first-order IIR filter. Use it if there is too much noise in analog command.

Function
Use
Select either auto or manual method for offset tuning of Analog Velocity Command.
For manual adjustment, use the parameter Analog velocity: offset value (No.60.0) for tuning.
Settings Offset tuning method
0
Auto:
Select this to automatically adjust the offset value, such that the speed command
becomes 0 r/min with the input voltage at the time of servo on.
1
Manual:
Select this to manually adjust the offset value, such that the speed command
becomes 0 r/min with 0 V input voltage.
