2. Control parameters
Control parameters include control commands, communication references, DO
control, AO1 control, AO2 control, and parameter initialization
● Control command
When F0‑02 (command source) is set to 2 (communication control), the host
controller can control the AC drive such as starting/stopping it by using the
communication address. The control commands are defined in the following
table.
Communication
Address of the AC

Status Definition
2000H
1: Forward run
2: Reverse run
3: Forward jog
4: Reverse jog
5. Coast to stop
6: Decelerate to stop
7: Fault reset
● Communication reference
The communication references apply to the data setting through
communication, such as the frequency, torque upper limit, V/f separation
voltage, PID reference, and PID feedback. If the communication address is
1000H, its range is ‑10000 to +10000 and the corresponding value range is
‑100.00% to +100.00%.
● DO control
When a DO is assigned with function 20 (communication), the host controller
can control the DO of the AC drive through the communication address. Control
on the DO of the AC drive is defined as follows.

Bit0: DO1 output control
Bit1: DO2 output control
Bit2: RELAY1 output control
Bit3: RELAY2 output control
Bit4: FMR output control
● AO1, AO2, high‑speed pulse (FMP) output control
When AO1, AO2, and FMP are assigned with function 12 (communication), the
host controller can control the AO and high‑speed pulse output terminal
through the communication addresses. The definition is described in the
following table.
