[Pr. Pc21_Alarm History Clear (*Bps)]; [Pr. Pc24_Deceleration Time Constant At Forced Stop (Rsbr)] - Mitsubishi Electric Melservo-Jet MR-JET-G User Manual

[Pr. PC21_Alarm history clear (*BPS)]

Initial value
00000000h
[Pr. PC21.0_Alarm clear history selection]
Initial value
0h
0: Disabled
1: Enabled
When "1" (enabled) is selected, the alarm history will be cleared at either the next power cycle, at software reset, or at
controller reset. After the alarm history is cleared, "0" (disabled) will be set to this servo parameter automatically.

[Pr. PC24_Deceleration time constant at forced stop (RSBR)]

Initial value
100 [ms]
Set the deceleration time constant for the forced stop deceleration function.
Set the time taken from the rated speed to 0 [r/min] (0 [mm/s]) in units of ms.
When "0" is set, the deceleration time constant is the same as when "100" is set.
Rated speed
Servo motor speed
This servo parameter corresponds to [Quick stop deceleration (Obj. 6085h)]. When the object is mapped to the cyclic
communication, do not write values with engineering tools because the controller overwrites the servo parameter values
written with engineering tools.
This servo parameter is enabled when [Pr. PT01.1 Speed/acceleration/deceleration unit selection] is set to "0". This servo
parameter and [Pr. PV09 Deceleration at forced stop] are mutually exclusive.
• If the servo motor torque or thrust is saturated at the maximum value during forced stop deceleration because the set time
is too short, the time to stop the servo motor will be longer than the set time constant.
• [AL. 050 Overload 1] or [AL. 051 Overload 2] may occur during forced stop deceleration, depending on the set value.
• After an occurrence of an alarm to execute forced stop deceleration, if another alarm that does not execute forced stop
deceleration occurs, or if the power supply is shut off, dynamic braking will start regardless of the deceleration time
constant setting.
• Set a longer time than deceleration time at quick stop of the controller. If the setting time is too short, [AL. 052 Excessive
error] may occur.
• During forced stop deceleration, changes in the setting value are not reflected. If the setting value is changed during forced
stop deceleration, the change will be reflected after the deceleration is completed.
