CAUTION
Never adjust or change the parameter values extremely as it will make operation
instable.
5.1 DRU parameter list
5.1.1 DRU parameter write inhibit
POINT
After setting the DRU parameter No. 19 value, switch power off, then on
to make that setting valid.
In the MELSERVO-J2M servo amplifier, its parameters are classified into the DRU basic parameters
(No. 0 to 19), DRU expansion parameters 1 (No. 20 to 49) and DRU expansion parameters 2 (No.50 to
84) according to their safety aspects and frequencies of use. In the factory setting condition, the
customer can change the basic parameter values but cannot change the DRU expansion parameter
values. When fine adjustment, e.g. gain adjustment, is required, change the DRU parameter No. 19
setting to make the expansion parameters write-enabled.
The following table indicates the parameters which are enabled for reference and write by the setting of
DRU parameter No. 19. Operation can be performed for the DRU parameters marked
.
