6.8 Offset Adjustment of Analog Monitor Output (Fn00C)
This function is used to manually adjust the offsets for the analog monitor outputs (torque reference monitor
output and motor speed monitor output). The offset values are factory-set before shipping. Therefore, the user
need not usually use this function.
(1) Adjustment Example
An example of offset adjustment to the motor speed monitor is shown below.
Note:
• The adjustment value will not be initialized when parameter settings are initialized using Fn005.
• Make offset adjustment with a measuring instrument connected, so that the analog monitor output is zero. An
example of settings for a zero analog monitor output is shown below.
• While the servomotor is not turned ON, set the monitor signal to the torque reference.
• In speed control, set the monitor signal to the position error.
(2) Preparation
The following condition must be met to adjust the offsets of the analog monitor output.
• The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
