9-4-5 Inverter Function Code Access

All of the inverter function codes are accessible through the RS-485 serial interface. Inverter function codes
are mapped to RTU holding registers. An inverter function code RTU address is 2 bytes in length. The high
byte corresponds to a code that represents the inverter parameter sort (F

–M). The low byte corresponds to

the inverter parameter number within the sort (0 -99).

For example, inverter function code M11, output current, is addressed as RTU parameter number 080B
hexadecimal or 2059 decimal.

9-4-6 Command and Monitor Data Registers

The command and monitor function codes are used to control the operation of the inverter and monitor the
status variables through the serial interface. The command and monitor function codes are not accessible
from the inverter keypad interface. Inverter parameter H30 and digital input signal LE must be enabled to
operate the inverter from the Modbus interface. If LE is not assigned to a digital input (X1-X9), the signal will
default to ON.

Note:
1) If both S01 and S05 are set, the inverter will ignore the setting of S05.
2) A data setting that exceeds the setting range is possible, but the actual action will be limited by the inverter
configuration.

Note:
1) Since X1

–X9 are configurable input commands, it is necessary to set the functions by E01–E09.

2) The alarm reset is executed, when RST signal changes from ON to OFF even if there are no alarms.
3) Universal Do is a function that utilizes the inverter

’s digital outputs via communication.
