Parameter Automatic Setting - Mitsubishi Electric MR-J5-G User Manual

Parameter automatic setting

The parameters of the servo amplifier are held by the master station, and are compared with those of the replaced servo
amplifier. When there is a difference in those parameters, the parameters held by the CPU module are automatically written to
the replaced servo amplifier.
Storage method of parameters
There are following two ways to store parameters in the master station.
• If data in the non-volatile memory of the servo amplifier are rewritten by the engineering tool, the parameters in the CPU
module are also updated automatically.
• If differences from the previously stored parameters are found in a periodical check, the parameters in the CPU module are
also updated automatically (Set an interval in [Pr. PN20 Parameter automatic backup update interval] for that periodical
check).
Parameters that can be stored
The parameters that can be written on the servo amplifier and stored with this function are as follows.
• Servo parameters
• Network parameters
• When the parameter that requires power cycling after being set is changed by the parameter automatic
setting, [AL. 09E.7 Parameter unreflected warning] occurs. Cycle the power of the servo amplifier.
• Do not turn off the power supply of the controller during backup. Before turning off the power supply of the
controller, check the rewrite-status of the parameter file of the device station by using the event history
function of the controller.
• Parameters that are automatically updated by the servo amplifier, such as auto tuning data, may not match
the data stored in the device station parameter file on the controller. To match the data, first read the servo
amplifier parameters using MR Configurator2 or other engineering tools, then reflect the readings on the
device station parameter file on "Detail Setting" in "Parameter Automatic Setting" of GX Works3 before
writing the readings to the controller again. Or, set [Pr. PN20 Parameter automatic backup update interval]
so that the data can be backed up in the master station periodically.
• If performing automatic backup with the interval set in [Pr. PN20], use a master station which features power
interruption protection. Failing to do so triggers [AL. 19E.1 Parameter automatic backup setting warning]. At
this time, the automatic backup is disabled.
• If the network topology is changed after the power has been turned on, the backup may not be performed.
