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.
The MD380 provides five curves indicating the mapping relationship between the input
voltage of AI1, AI2 and AI3 and the target frequency, three of which are linear (point-
point) correspondence and two of which are four-point correspondence curves. You can
set the curves by using function codes F4-13 to F4-27 and function codes in group A6,
and select curves for AI1, AI2 and AI3 in F4-33.
When AI is used as frequency setting source, the corresponding value 100% of voltage/
current input corresponds to the value of A0-03.
• 5: Pulse setting (DI5)
The target torque is set by DI5 (high-speed pulse). The pulse setting signal specification
is 9–30 V (voltage range) and 0–100 kHz (frequency range). The pulse can only be
input via DI5. The relationship (which is a two-point line) between DI5 input pulse
frequency and the corresponding value is set in F4-28 to F4-31. The corresponding
value 100.0% of pulse input corresponds to the value of A0-03.
• 5: Communication setting
The target torque is set by means of communication.
If the AC drive is a slave in point-point communication and receives data as torque
source, data transmitted by the master is used as the setting value. For details, see the
description of group A8.
If PROFIBUS-DP communication is valid and PZD1 is used for torque setting, data
transmitted by PDZ1 is directly used as the torque source. The data format is -100.00%
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,
