Example: In the case that M09 (output frequency) = +60.00 Hz
60.00 ¥ 100 = 6000 (dec.) = 1770 (hex.), hence:
➾
Positive data is handled in a 4-byte ASCII code similarly to data format 0.
• In the case that M09 (output frequency) = -60.00 Hz
60.00 x 100 = 6000 (dec.) = 1770 (hex.). An ASCII code of the minus sign is added at the top.: -1770

Note 1: Tuning is started upon a terminal block
operation command. After tuning is completed,
an ACK response is given. (The ACK response
is given before the terminal block is turned off.) Note 2: After data is written via RS485, tuning
is started. After tuning is completed, an ACK
response is given. (The operation command is
automatically turned off.)
