Connection to Pulse Train Command Signal
Control Mode
P V T
Use this for pulse train input in Position Control mode.
You can set the form of pulse signal input with Pulse train command: Input mode (No.32.0)
In case of positional aberration due to noise, take noise countermeasures, for example,
1) Make the signal line short between the host controller and the amplifier.
2) Be sure to use shielded twist-pair cables for the signal lines.
3) Segregate the signal lines from the primary circuit power cable and the motor power cable.
4) Adjust Pulse train command: Input filter (No.33.0).
