◆ H6: PULSE 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 PI. 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.
A pulse train signal with a maximum frequency of 32 kHz can be output from the drive output terminal PO as the
monitor value. Sinking mode and sourcing mode are supported.

PI Pulse Train Function
Sets the function for pulse train input terminal RP.
0
(0 - 3)
0 : Freq Ref
When b1-01 [Freq. Ref. Sel. 1] or b1-15 [Freq. Ref. Sel. 2] = 4 [Pulse Train Input], the drive inputs the frequency
reference received from terminal RP.
1 : PIDFbk Value
The drive inputs the PID control feedback value received from terminal PI.
2 : PID SP Value
The drive inputs the PID control target value received from terminal PI.
3 : PG Feedback
Select V/f Control method to enable simple encoder feedback.
Use motor speed feedback for better speed control precision. The drive compares the frequency reference to the
motor speed feedback received from the encoder, and uses the ASR function to compensates for motor slip. You
cannot use input terminal RP used for the simple encoder to detect the direction of motor rotation. Use a different
method to detect motor rotation.
Use these methods to detect the direction of motor rotation.
• Use DI
Set DI H1-xx = 15 [FWD/REV Det]. When the configured terminal is activated, the motor operates in Reverse
run. When the terminal is deactivated, the motor operates in Forward run.
Use an encoder that outputs 2-tracks (phase A, B) to detect the direction of motor rotation.
