2) PLC Word Device X and Y are in octal format. Other PLC Word Device M, S, T, C, D and HC are in
decimal format.
3) Servo Digital Input and Servo Digital Output are only for Servo.
Pay close attention to the following important notes:
4) For Delta AC drive:
Communication address for HMI read/write address uses hexadecimal format. For detailed information
about communication address of Delta AC drive, please refer to Delta AC drive "User Manual".
Example 1: Parameter 9-01 of Delta VFD-S drive Transmission Speed needs to be set to INVERTER901
in HMI. (Decimal 9 is converted to 09 in hexadecimal and 01 is converted to 01 in hexadecimal.
Therefore, setting INVERTER901 to HMI will discard the first 0)
The communication address of parameter 9-01 is 0901H.
Example 2: if setting of parameter 8-17 (Lower Bound of DC Braking Start-up Frequency) of Delta VFD-
S drive is desired, user needs to set INVERTER811 in HMI. (8 is converted to 08 in hexadecimal and 17
is converted to 11 in hexadecimal. Therefore, setting the INVERTER811 to HMI will discard the first 0)
The communication address of parameter 8-17 is 0811H.
5) For Delta Servo drive:
HMI Read/Write address setting needs to input the communication address listed in SERVO "User
Manual".
Servo Digital Input and Servo Digital Output are only for Servo.
6) For Delta Temperature Controller (DTA series):
HMI can be set up to connect to several Delta A series temperature controllers on standard Modbus
networks by using RTU transmission mode. However, the communication delay time may need to
increase. Therefore, 5ms or longer is highly recommended.
