■ Selection of tuning method (basic para. 31)
Basic parameter 31
Para. Name Setting range Initial value Change
31 Tuning method 0: Manual 1: Auto (low stiffness) 2: Auto (high stiffness) 1 Always
Basic parameter 31
Set value Target machine
1: Auto (low stiffness) Ball-screw (with speed reducer)
Spindle drive (with speed reducer)
Rack and pinion
Timing belt
Conveyor
Chain drive
Feed roll
Table indexing (dividing)
2: Auto (high stiffness) Ball-screw (direct coupling of motor and screw)
Spindle drive (direct coupling)
0: Manual All of the para. must be set individually.
Set this para. according to mechanical equipment system. In general, the auto (low stiffness) is selected for most of mechanical equipment
system.
When the manual is set, automatic regulation regarding the response is not made, and the setting value of each parameter is used.
When the auto (low stiffness) or auto (high stiffness) is selected, the load inertia is assumed and automatic regulation regarding the
response is made according to the basic para. 33 setting.
■ Operating speed response (basic para. 33)
Basic parameter 33
Para. Name Setting range Initial value Change
33 Operating speed response 10 to 1000 [Hz] (in 1 step) 100 Always
Use the motor with the initial value of 100 [Hz] in ordinary mechanical equipment system. The higher is the set value, the quicker is the
motor’s response rate. Mechanical equipment system having direct-coupled ball-screw can have a higher set value (higher response rate as
well).
The following 3 basic para. can be automatically adjusted according to the setting value of the operating speed response (basic para. 33).
Basic parameter 37 to 39
Para. Name Setting range Initial value Change
37 Torque filter time constant 0.00 to 20.00 [ms] (in 0.01 step) 0.30 Always
38 Speed regulator integration time 1 to 1000 [ms] (in 1 step) 20 Always
39 Position regulator gain 1 to 1000 (in 1 step) 50 Always
Basic para. 37 to 39 can be adjusted when the auto has been selected in the tuning method (basic para. 31) and when the basic para. 33
setting changed.
Remark : Basic para. 37 to 39 can also be set manually after these have been changed by the amplifier. Usually the amplifier set value is
used.
