„ ASR Switching Time (d25) Data setting range: 0.000 to 1.000 (s)
Parameter switching is possible even during operation. For example, speed control P (Gain) and I (Integral time) listed in
Table 5.5 can be switched.
Switching these parameters during operation may cause an abrupt change of torque and result in a mechanical shock,
depending on the driving condition of the load.
To reduce such a mechanical shock, the inverter decreases the abrupt torque change using the ramp function of ASR
Switching Time (d25).
