A0-01 is used to set the torque setting source. There are a total of eight torque setting
sources.
The torque setting is a relative value. 100.0% corresponds to the AC drive's rated torque.
The setting range is -200.0% to 200.0%, indicating the AC drive's maximum torque is twice
of the AC drive's rated torque.
If the torque setting is positive, the AC drive rotates in forward direction. If the torque setting
is negative, the AC drive rotates in reverse direction.
 1: Digital setting (A0-03)
The target torque directly uses the value set in A0-03.
 2: AI1
 3: AI2
 4: AI3
The target torque is decided by analog input. The MD380 control board provides two AI
terminals (AI1, AI2). Another AI terminal (AI3) is provided by the I/O extension card. AI1
is 0–10 V voltage input, AI2 is 0–10 V voltage input or 4–20 mA current input decided
by jumper J8 on the control board, and AI3 is -10 V to +10 V voltage input.

When AI is used as frequency setting source, the corresponding value 100% of voltage/
current input corresponds to the value of A0-03.

to 100.00%. 100% corresponds to the value of A0-03.
In other conditions, data is given by host computer through the communication address
0x1000. The data format is -100.00% to 100.00%. 100% corresponds to the value of
A0-03.
The MD380 supports four host computer communication protocols: Modbus,
