3.2.12 Gain Adjustment of Analog Monitor Output (Fn00D)
This function is used to manually adjust the gains for the analog monitor outputs
(torque reference monitor output and motor speed monitor output). The gain values
are factory-set before shipping. Therefore, the user need not usually use this function.
The setting range of the gain adjustment width for analog monitor output is
-128 to +127 (
× 0.4%).
The setting of gain adjustment width is made on the base of 100 %. For example, the
setting “-125” makes 100 % - (125 × 0.4%) = 50%, which means that the monitor
output voltage is 1/2. The setting “125” makes 100 % + (125 × 0.4%) = 150%, which
means that the monitor output voltage is 1.5 times.
Note: The adjustment value will not be initialized when parameter settings are initialized using
Fn005.
(1) Preparation
The following condition must be met to adjust the gain of the analog monitor output.
• The write prohibited setting (Fn010) must not be set to write-protect parameters.
(2) Operating Procedure
Use the following procedure.
