◆ H5: MEMOBUS/Modbus Serial Communication

Through the drives built in RS-422/RS-485 port (terminals R+, R-, S+, S-), serial communication is possible using
programmable logic controllers (PLCs) or similar devices running the MEMOBUS/Modbus protocol.
The H5- parameters are used to set up the drive for MEMOBUS/Modbus Communications.
Modbus Serial Communication on page 416

◆ 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 PI 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. It can be used in sinking or sourcing mode.
Use parameters H6- to set the scale and other aspects of the pulse input terminal RP and pulse output terminal MP.
