Operation selection function parameters

2.10.4 Input filter time constant (Pr. 74 )

You can set the input section's built-in filter constant for an external voltage or current frequency setting signal.

Effective for eliminating noise in the frequency setting circuit.

	constant

<Setting>

Increase the filter time constant if steady operation cannot be performed due to noise. A larger setting results in slower response. (The time constant can be set between approximately 1ms to 1s with the setting of 0 to 8. A larger setting results in a larger filter time constant.)

2.10.5 Reset selection/PU stop selection (Pr. 75 )

You can make reset input acceptance selection and choose the stop function
from the operation panel (PU).
Reset selection :You can choose the reset function input (RES signal) timing.
PU stop selection :When an alarm etc. occurs in any operation mode, you can
		make a stop from the operation panel by pressing the					STOP .
