5. PARAMETERS
No./ Setting
symbol/name digit
Set a deceleration time constant for the forced stop deceleration function.
PC24
Set the time taken from the rated speed to 0 r/min or 0 mm/s in units of ms. Setting
RSBR
"0" will apply 100 ms.
Forced stop
deceleration
time constant
Servo motor speed
[Precautions]
This parameter corresponds to "Quick stop deceleration (Index: 6085h)". When this
parameter is mapped for the PDO communication, the value written with MR
Configurator2 is overwritten with the controller. Thus, do not write a value with MR
Configurator2.
Setting range: 0 to 20000
Set a deceleration time constant for the forced stop deceleration function.
Set the time taken from the rated speed to 0 r/min or 0 mm/s in units of ms. Setting
"0" will apply 100 ms.
Servo motor speed
[Precautions]
This parameter corresponds to "Quick stop deceleration (Class ID: 64h, Ins ID:
6085h, Attr ID: 0)". When this parameter is mapped for the I/O communication, the
value written with MR Configurator2 is overwritten with the controller. Thus, do not
write a value with MR Configurator2.
Setting range: 0 to 20000
Rated speed
0 r/min
(0 mm/s)
If the servo motor torque or linear servo motor 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. 50 Overload 1] or [AL. 51 Overload 2] may occur during forced stop
deceleration, depending on the set value.
After an alarm that leads to a forced stop deceleration, if an alarm that does not
lead to a forced stop deceleration occurs or if the control circuit power supply is
cut, dynamic braking will start regardless of the deceleration time constant setting.
