Writing to Multiple Inverter Memory Registers
The writing of inverter memory registers works similar to the reading process, i.e. the address of the first reg-
ister that is to be written and the quantity of to be written registers must be set in the command message.
The to be written data must be consecutive, starting from the specified address in the command message. The
data order must be higher 8 bits, then lower 8 bits. The data must be in memory register address order.
The following table shows an example of a message where a forward operation has been set with a frequency
reference of 60.0 Hz for the inverter with the slave address 01H.
