<3> The number of decimal places in the parameter value depends on the drive model. This value has two decimal places (0.01 A) in drive models
2A0011 to 2A0046 and 4A0005 to 4A0021; this value has one decimal place (0.1 A) in drive models 2A0059 to 2A0396 and 4A0027 to 4A0590.
<4> Set the number of motor poles to parameter E2-04, E4-04, or E5-05 depending on the motor being used.
Broadcast Messa es
Data can be written from the master to all slave devices at the same time.
The slave address in a broadcast command message must be set to 00H. All slaves will receive the message, but will not
respond.
