H4-07, H4-08: Multi-Function Analog Output Terminal FM, AM Signal Level Selection
Sets the voltage output level of U parameter (monitor parameter) data to terminal FM and terminal AM using parameters
H4-07 and H4-08.
When changing the setting of these parameters make sure jumper S5 on the terminal board is set accordingly. Refer to
Terminal AM/FM Signal Selection on page 67

u H5: MEMOBUS/Modbus Serial Communication
Through the drives built in RS-422/485 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 450
u 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.
