Enter Command
When writing parameters to the iQpump drive from the PLC using Modbus communication, the parameters are temporarily stored in the
constant data area in the Drive. To enable these parameters in the parameter data area, use the Enter command.
There are two types of Enter commands:
1. Enter commands that enable parameter data in RAM
2. Enter commands that write data to EEPROM (non-volatile memory) in the iQpump drive at the same time as enabling data in RAM.
The following table shows the Enter command data. Enter command data can only be written.
The Enter command is enabled by writing 0 to register number 0900H or 0901H.
Table 25 Enter Command
Important: The maximum number of times you can write to EEPROM using the iQpump drive is 100,000. Do not frequently execute
Enter commands (0900H) written to EEPROM.
The Enter command registers are write-only. Consequently, if reading these registers, the register address will become invalid (Error
code: 02H).
