PARAMETERS
[Drive unit status monitor]
∗ The signal is the initial setting. The description changes depending on the Pr. 190, Pr. 192 (output terminal function selection).
[Multi command (HF0)]
Sending data format from computer to drive unit
Reply data format from drive unit to computer (No data error detected)
∗1 Specify the data type of sending data (from computer to drive unit).
∗2 Specify the data type of reply data (from drive unit to computer).
∗3 Combination of data 1 and data 2 for sending
∗4 Combination of data 1 and data 2 for reply
∗5 Error code for sending data 1 is set in error code 1, and error code for sending data 2 is set in error code 2.
