H5: MEMOBUS/Modbus Serial Communication

Serial communication is possible in the drive using the built-in RS-422/485 port (terminals R+, R-, S+, S-) and programmable
logic controllers (PLCs) or similar devices running the MEMOBUS/Modbus protocol.
The H5-oo parameters set the drive for MEMOBUS/Modbus Communications.

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 can output drive monitor values as a pulse train signal with a maximum frequency of
32 kHz in sinking or sourcing mode.
Use parameters H6-oo to set the scale and other aspects of the pulse input terminal RP and pulse output terminal MP.
n H6-01: Pulse Train Input Terminal RP Function Selection
Selects the function of pulse train input terminal RP.
No.
H6-01 Pulse Train Input Terminal RP Function Selection
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, b1-15 = 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.
Control on page 141 for details on PID control.
