n H2-07 to H2-10: MEMOBUS Registers
These parameters specify the MEMOBUS/Modbus registers and bits from which data will be sent to the multi-function contact
outputs.
No. Name Setting Range Default
H2-07 MEMOBUS Register 1 Address Select 1 to 1FFFH 1
H2-08 MEMOBUS Register 1 Bit Select 0 to FFFFH 0
H2-09 MEMOBUS Register 2 Address Select 1 to 1FFFH 1
H2-10 MEMOBUS Register 2 Bit Select 0 to FFFFH 0
The MEMOBUS/Modbus register addresses for sending data to multi-function contact outputs 62 and 63 are specified in
H2-07 and H2-09, and the bits for the MEMOBUS/Modbus registers are specified in H2-08 and H2-10.

H3: Multi-Function Analog Inputs
The drive is equipped with three multi-function analog input terminals: A1, A2, and A3. Refer to Multi-Function Analog
Input Terminal Settings on page 301 for a listing of the functions that can be set to these terminals.
n H3-01: Terminal A1 Signal Level Selection
Selects the input signal level for analog input A1.
No. Name Setting Range Default
H3-01 Terminal A1 Signal Level Selection 0 to 1 0
Setting 0: 0 to 10 Vdc
The input level is 0 to 10 Vdc. The minimum input level is limited to 0%, so that a negative input signal due to gain and bias
settings will be read as 0%.
Setting 1: -10 to 10 Vdc
The input level is -10 to 10 Vdc. If the resulting voltage is negative after being adjusted by gain and bias settings, then the
motor will rotate in reverse.
n H3-02: Terminal A1 Function Selection
Selects the input signal level for analog input A1. Refer to Multi-Function Analog Input Terminal Settings on page 301
for instructions on adjusting the signal level.
No. Name Setting Range Default
H3-02 Terminal A1 Function Selection 0 to 32 0
n H3-03, H3-04: Terminal A1 Gain and Bias Settings
Parameter H3-03 sets the level of the selected input value that is equal to 10 Vdc input at terminal A1 (gain).
Parameter H3-04 sets the level of the selected input value that is equal to 0 V input at terminal A1 (bias).
Use both parameters to adjust the characteristics of the analog input signal to terminal A1.
