User manual BENSHAW RSI (H-SERIES) MODBUS CARD

[. . . ] The card supports four Modbus commands; Read Holding Registers (0x03), Read Input Registers (0x04), Preset Single Register (0x06) and Preset Multiple Registers (0x10). 2. Installation 2. 1 Card Layout Standoff holes ERR TXD RXD CPU Indication LEDs Connector to inverter main PCB S GND T2 T1 N P Terminal block for Modbus connection 4 INSTALLATION 2. 2 1. 5. Card Installation Turn off the main power of Inverter. Wait until the DC bus capacitors are discharged. [. . . ] Registers can be read with either the Read Holding Registers command (0x03) or the Read Input Registers command (0x04). Those registers that may be changed can be done so using the Preset Single Register (0x06) or the Preset Multiple Registers command (0x10). A maximum of 8 registers can be read or written at a time. 3. 1 Mutual Group The registers in the Mutual Group contain meter and status information that is not available in the other groups. Also, all of the registers from the Drive Group are duplicated in the Mutual Group. The values will only be used until power to the drive is lost. Once power is lost, these registers will return to the last values set through the Drive Group. To permanently change the command frequency, acceleration time or deceleration time, use registers 16384 (Cmd. time) instead.
