5.7 H: Terminal Functions

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 90
No.

Multi-Function Analog Output Terminal AM Signal Level Selection
Setting 0: 0 to 10 V
Setting 1: -10 V to 10 V
Setting 2: 4 to 20 mA
 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 550
 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. 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.

H6-01: Pulse Train Input Terminal RP Function Selection
Selects the function of pulse train input terminal RP.
No.
H6-01
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 167 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.
Control on page 167 for details on PID control.
