5.4 MP2000 Series Machine Controller Parameter Details
5.4.2 Motion Setting Parameter Details
5-36
( 22 ) Latch
( 23 ) Gain and Bias Settings
OL 2A
Latch Zone Lower Limit Setting
Setting Range Setting Unit Default Value
−2 31 to 2 31 −1 Reference unit −2 31
Description Set the range in which the latch signal is valid (position from the zero position) for external positioning.
OL 2C
Latch Zone Upper Limit Setting
Setting Range Setting Unit Default Value
−2 31 to 2 31 −1 Reference unit 2 31 −1
Description Same as for OL 2A.
OW 2E
Position Loop Gain
Setting Range Setting Unit Default Value
0 to 32767 0.1/s 300
Description
Determine the responsiveness for the SERVOPACK’s position loop.
If the position loop gain is set high, the responsiveness is high and the positioning time is short. Set the optimum value for
the machine rigidity, inertia, and type of Servomotor.
OW 30
Speed Feedforward Amends
Setting Range Setting Unit Default Value
0 to 32767 0.01% 0
Description
Reduces positioning time by applying feed forward compensation.
This setting is effective for positioning control commands. Always set this parameter to 0 for phase control.
OW 31
Speed Compensation
Setting Range Setting Unit Default Value
−32768 to 32767 0.01% 0
Description
Set the speed feed forward gain as a percentage of the rated speed for the phase reference (PHASE) com-
mands.
The setting unit for this parameter is 0.01% (fixed).
Secondly Speed Compensation (OL 16) can be used with the phase reference command (PHASE) , and
the unit can be selected for OL 16. When used at the same time as OL 16, speed compensation can
be applied twice.
OW 32
Position Integration Time Constant
Setting Range Setting Unit Default Value
0 to 32767 ms 0
Description
Set the position loop integration time constant.
Use this parameter to improve the following precision in applications such as electronic cams or shafts.
Setting this parameter to 0 clears the integral elements in the position control loop during position control and phase con-
trol.
OW 33
1st-order Lag Time Constant
Setting Range Setting Unit Default Value
0 to 32767 ms 0
Description
Set the primary lag time constant (1 = 1ms) for position loop.
When this parameter is set to 0, the primary lag calculation will not be performed.
This parameter is used in position control mode or zero point return mode.
Setting the primary lag time constant may cause vibration. Set this parameter to 0 unless it is abso-
lutely necessary.
