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

(0 - 3)
0 : Frequency Reference
When b1-01 [Frequency Reference Selection 1] or b1-15 [Frequency Reference Selection 2] = 4 [Pulse Train
Input], the drive inputs the frequency reference received from terminal RP.
1 : PID Feedback Value
The drive inputs the PID control feedback value received from terminal RP.
2 : PID Setpoint Value
The drive inputs the PID control target value received from terminal RP.
3 : Speed Feedback (V/F Control)
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.
