1.7 H: Terminal Functions
182 YASKAWA ELECTRIC SIEP C710606 10A YASKAWA AC Drive - V1000 PRELIM. Programming Manual
The H5- parameters are used to set up the drive for MEMOBUS/Modbus
Communications. Refer to MEMOBUS/Modbus Serial Communication on page 262 for
detailed descriptions of the H5- parameters.
◆ H6: Pulse Train Input/Output
A one track pulse train signal with a maximum frequency of 32 kHz can be input to the drive
at terminal RP. This pulse train signal can be used as the frequency reference, for PID
functions, or as the speed feedback signal in V/f Control.
The pulse output monitor terminal MP, which can be used in sinking or sourcing mode, can
output drive monitors values as a pulse train signal with a maximum frequency of 32 kHz.
Use parameters H6- to scale and set up the function for the pulse input terminal RP and
pulse output terminal MP.
■ H6-01: Pulse Train Input Terminal RP Function Selection
Selects the function of pulse train input terminal RP.
Setting 0: Frequency Reference
If the pulse input is set for this function and the frequency reference source is set to pulse
input (b1-01/15 = 4), the drive reads the frequency value from terminal RP.
Setting 1: PID Feedback Value
Using this setting, the feedback value for PID control can be supplied as a pulse signal at
terminal RP. Refer to b5: PID Control on page 59 for details on PID control.
Setting 2: PID Setpoint Value
Using this setting, the setpoint value for PID control can be supplied as a pulse signal at
terminal RP. Refer to b5: PID Control on page 59 for details on PID control.
Setting 3: Speed Feedback for V/f Control (V/f Control only, Motor 1 only)
This setting enables simple speed feedback for V/f Control. A pulse signal can be used to
input the motor speed to the drive and thereby improve the speed control accuracy. Note that
this speed feedback can only be a one track signal that can not be used for direction
detection. The drive needs a separate motor rotation direction signal. Refer to C5:
Automatic Speed Regulator (ASR) on page 86 for details on using Simple V/f Control with
Speed Feedback.
