3.2.11 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.
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.
(1) Preparation
The following condition must be met to adjust the offsets of the analog monitor out-
put.
• The write prohibited setting (Fn010) must not be set to write-protect parameters.
(2) Operating Procedure
Use the following procedure.
