What is the data backup battery for the SPH Series used to back up? Are there any precautions in performing a battery-less operation?
(1) With the SPH300/2000 Series, it is used to back up the data memory of the retained attributes, calendar IC memory, and RAS information.
(2) With the SPH2...

I used the high-speed counter module (Type_NP1F-HC2) but it doesn't count. I didn't make any settings in particular.
The counter is initially set to gate mode. Counting is disabled unless you provide a 'gate signal' externally by hardware or set 'gate disabled' by software....

Which is the signal that indicates pulse output completion on the positioning control module (Type_ NP1F-MP2)?
Pulse output completion is indicated by the 'Command pulse zero' signal.
Normally, it is '1' to indicate the status of completion. When the number of pulses...

I heard that the high-speed counter module (Type_ NP1F-HC2) requires a current value less than 40 mA for frequencies up to 50 kHz.
The specified current value is constant regardless of the frequency because the input impedance for the pulse input I/F is fixed.

How can I provide Z-phase pulses when the equipment connected with the positioning control module (Type_ NP1F-MP2/MA2) uses a stepping motor?
Use the 'Excitation timing output' signal for the Z-phase pulse when a stepping motor is used.
