[Pr. Pe46_Lost Motion Filter Setting (Lmflt)]; [Pr. Pe47_Unbalanced Torque Offset (Tof)]; [Pr. Pe48_Lost Motion Compensation Function Selection (*Lmop)]; [Pr. Pe49_Lost Motion Compensation Timing (Lmcd)] - Mitsubishi Electric MELSERVO-J5 MR-J5-G Series User Manual

[Pr. PE46_Lost motion filter setting (LMFLT)]

Initial value
0 [0.1 ms]
When "0" is set, the value is compensated with the compensation amount of the value that was set in [Pr. PE44 Lost motion
compensation positive-side compensation - Value selection] and [Pr. PE45 Lost motion compensation negative-side
compensation - Value selection]. When a value other than "0" is set, the torque is compensated with the high-pass filter output
value of the set time constant, and the lost motion compensation will continue.

[Pr. PE47_Unbalanced torque offset (TOF)]

Initial value
0 [0.01 %]
Set this to cancel the unbalanced torque of vertical axis. Set this assuming the rated torque of the servo motor as 100 %. The
torque offset does not need to be set for a machine that does not generate unbalanced torque. This servo parameter can be
used in an application where an unbalanced torque is generated constantly. For example, a linear servo motor or direct drive
motor operates horizontally with tension applied in one direction.
The torque offset that has been set with this servo parameter is enabled in any control mode. In the torque mode, input
commands taking the torque offset into account.
This servo parameter is suitable when the torque offset does not need to be changed dynamically.

[Pr. PE48_Lost motion compensation function selection (*LMOP)]

Initial value
00000000h
[Pr. PE48.0_Lost motion compensation type selection]
Initial value
0h
0: Lost motion compensation is disabled.
1: Lost motion compensation is enabled.
[Pr. PE48.1_Lost motion compensation non-sensitive band - Unit setting]
Initial value
0h
0: 1 pulse unit
1: 1 kpulse unit

[Pr. PE49_Lost motion compensation timing (LMCD)]

Initial value
0 [0.1 ms]
Set the lost motion compensation timing in 0.1 ms unit.
The timing to perform the lost motion compensation function can be delayed by a set time.

[Pr. PE50_Lost motion compensation non-sensitive band (LMCT)]

Initial value
0 [pulse], [kpulse]
Set the lost motion compensation non-sensitive band. When the fluctuation of droop pulses is equal to or less than the setting
value, the speed is recognized as 0. The setting unit can be changed with [Pr. PE48 Lost motion compensation function
selection]. Set the servo parameter per encoder unit.
