Parameter Setting

4 Parameter setting

4.1 Register Memory

4.1.1 Read Only or Input Registers

The following read only ModBus registers (drive variables) accessible only through the ModBus

function

• 03 (0x03) Read Holding Registers

4.1.2 Read/Write or Holding Registers

The following read/write ModBus registers (drive variables) accessible only through the ModBus

functions

• 04 (0x04) Read Input Registers

• 06 (0x06) Write Single Register

• 16 (0x10) Write Multiple Registers

For all ModBus registers that are denoted in description ﬁeld as ‘W: EPROM & memory’ exist another

of that variable, without affecting EEPROM value. Read command returns the same result for both

addresses.

Parameter changes in EEPROM and memory using ﬁrst set of addresses are permanent, however

parameter changes in memory only using second set of addresses are valid only for one session.

Session ends by powering the drive down.

Remember, when changing double word or ﬂoat parameters, the change is applied to the drive only

after second word is written.
