MHT258a (Engl.)6-5
6.1.5 Non-linear (S-curve) filter coefficient
The motor can be accelerated by drawing an S-curve.
Basic parameter 25
Para. Name Setting range Initial value Change
25 Non-linear (S-curve) filter coefficient 0.001 to 1.000s (in 0.001s steps) 0 Always
- Speed control
In speed control, S-shaped curve is drawn at the beginning and at the end of acceleration with the setting of the filter coefficient.
- Position control
Accel./decel. can be adjusted by using the time constant of the filter coefficient when the pulse train input is given by constant frequency.
The motor rotates as much as the pulse train input.
Even if the host controller cannot perform linear acceleration, smooth acceleration can be realized.
6.1.6 Auto-tuning
This function adjusts the motor’s response rate according to the mechanical equipment system.
Basic parameter 31 to 33
Para. Name Setting range Initial value Change
31 Tuning method 0: Manual
1: Auto (low stiffness)
2: Auto (high stiffness)
1Always
32 Load inertia ratio 0.0 to 100.0 (in 0.1 step) 0.0 Always
33 Operating speed response 10 to 1000Hz (in increments of 1) 100 Always
