Inverter signal input speed
I use the FR-A520 inverter.
When switching from high speed to low speed, the signal to the programmable controller switches and the timing when the inverter starts decelerating delays for 100 ms, resulting in overrun (because the inverter cannot stop in time).
Does the inverter take 100 ms for scanning before starting control after receiving the input signal?

Answer
There is a 10 ms delay after the inverter recognizes the start command (STF OR STR) before it starts decelerating. The delay is 10 ms.
A delay of 100 ms is irregular.
Check if the delay is caused by the sensor recognition, start command signal switching by the programmable controller, and/or relay operation.
