[Pr. Pt49_Speed Acceleration Time Constant (Sta)]; [Pr. Pt50_Speed Deceleration Time Constant (Stb)] - Mitsubishi Electric MELSERVO-J5 MR-J5-G User Manual

[Pr. PT49_Speed acceleration time constant (STA)]

Initial value
0 [ms]
Set the acceleration time taken by the motor to reach the rated speed from a full stop for the command.
Servo motor speed
Rated
speed
0 r/min
(0 mm/s)
Setting value of
[Pr. PT49]
For example, for a servo motor with a rated speed of 3000 [r/min], set 3000 [ms] to accelerate from 0 [r/min] to 1000 [r/min] in
1000 [ms].
This function is enabled in the profile position mode and profile velocity mode.
If a value larger than 20000 [ms] is set in the position mode, [AL. 0F4 Positioning warning] occurs.
This function corresponds to [Profile acceleration (Obj. 6083h)].
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 function is enabled when [Pr. PT01.1 Speed/acceleration/deceleration unit selection] is set to "0". This function and [Pr.
PV05 Profile acceleration] are mutually exclusive.

[Pr. PT50_Speed deceleration time constant (STB)]

Initial value
0 [pulse]
Set the deceleration time from the rated speed to a motor stop for the command.
This function is enabled in the profile position mode and profile velocity mode.
If a value larger than 20000 [ms] is set in the position mode, [AL. 0F4 Positioning warning] occurs.
This function corresponds to [Profile deceleration (Obj. 6084h)].
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 function is enabled when [Pr. PT01.1 Speed/acceleration/deceleration unit selection] is set to "0". This function and [Pr.
PV07 Profile deceleration] are mutually exclusive.
Setting range
0 to 50000
If the preset speed command is lower than
the rated speed, acceleration/deceleration
time will be shorter.
