CAUTION
Never adjust or change the parameter values extremely as it will make operation
instable.
POINT
When MELSERVO-J2M is connected with the servo system controller, the
parameters are set to the values of the servo system controller. Switching
power off, then on makes the values set on the MR Configurator (servo
configuration software) invalid and the servo system controller values valid.
In the maker setting parameters, do not set any values other than the
initial values.
Setting may not be made to some parameters and ranges depending on the
model or version of the servo system controller. For details, refer to the
servo system controller user's manual.
The IFU and DRU parameters can be set in the following methods.

POINT
When setting the parameter values from the servo system controller, the
DRU parameter No. 40 setting need not be changed.
In this drive unit, the parameters are classified into the basic DRU parameters (No. 1 to 11), adjustment
DRU parameters (No. 12 to 26) and expansion DRU parameters (No. 27 to 40) according to their safety
aspects and frequencies of use. The values of the basic DRU parameters may be set/changed by the
customer, but those of the adjustment and expansion DRU parameters cannot. When in-depth
adjustment such as gain adjustment is required, change the DRU parameter No. 40 value to make all
parameters accessible. DRU parameter No. 40 is made valid by switching power off, then on after setting
its value.
The following table indicates the parameters which are enabled for reference and write by DRU
parameter No. 40 setting.
