◆ H6: Pulse Train Input/Output
H6 parameters set the drive pulse train input and pulse train monitor. These parameters select input and monitor
parameters and adjust the pulse train frequency.
A pulse train signal with a maximum single pulse of 32 kHz can be input to the drive input terminal RP. You can use
the pulse train signal as the frequency reference, PID feedback value, PID setpoint value, and speed feedback for V/f
Control mode.
