[Pr. Pc31_Vertical Axis Freefall Prevention Compensation Amount (Rsup1)]; [Pr. Pc38_Excessive Error Warning Level (Erw)]; [Pr. Pc67_Following Error Output Level (Few)] - Mitsubishi Electric MELSERVO-J5 MR-J5-G Series User Manual

[Pr. PC31_Vertical axis freefall prevention compensation amount
(RSUP1)]
Initial value
0 [0.0001 rev], [0.01 mm]
Set the compensation amount of the vertical axis freefall prevention function.
Set the compensation amount in either the servo motor rotation amount unit or linear servo motor travel distance unit.
When a positive value is set, the compensation is performed to the command address increasing direction. When a negative
value is set, compensation is performed to the command address decreasing direction.
The vertical axis freefall prevention function is performed when all of the following conditions are met.
• The control mode is set for the position mode.
• The setting value of this servo parameter is other than "0"
• The forced stop deceleration function is enabled
• Alarm has occurred or EM2 has turned off when the servo motor rotates at the zero speed or less. Or, the Quick stop
command was issued.
• MBR (Electromagnetic brake interlock) was enabled in [Pr. PD07 Output device selection 1] to [Pr. PD09 Output device
selection 3], and the base circuit shut-off delay time was set in [Pr. PC02 Electromagnetic brake sequence output]

[Pr. PC38_Excessive error warning level (ERW)]

Initial value
0 [rev], [mm]
Set the excessive error warning level.
The unit can be changed with [Pr. PC06.3 Excessive error alarm/excessive error warning level unit selection].
For rotary servo motor and direct drive motor, set in rev unit. If 200 rev or higher is set, the value will be clamped to 200 rev.
For linear servo motors, set in mm unit.
When "0" is set, [AL. 09B Excessive error warning] does not occur.
When an error reaches the set value, [AL. 09B] occurs. Afterwards, when the error becomes less than the setting value, the
warning is automatically canceled. The minimum pulse width of the warning signal output is 100 [ms].
Set this servo parameter to meet the condition of [Pr. PC38 Excessive error warning level] < [Pr. PC01 Excessive error alarm
level]. When set as [Pr. PC38] ≥ [Pr. PC01], [AL. 052 Excessive error] occurs before the warning.

[Pr. PC67_Following error output level (FEW)]

Initial value
00C00000h [pulse]
Set the output level of the following error output.
When the state of "droop pulses ≥ the parameter setting value" continues for the time set in [Pr. PC69 Following error output
filtering time], bit 13 (Following error) of [Statusword (Obj. 6041h)] turns on.
If "FFFFFFFFh" is set, the following error output will be disabled.
Set the value in hexadecimal.
This servo parameter corresponds to [Following error window (Obj. 6065h)]. When this object is mapped to the cyclic
communication, the controller overwrites the servo parameter value written with an engineering tool or others. Thus, do not
write a value with the engineering tool or others.
