A1-21 VDO state selection
Unit's digit (VDO1)
00000
0: Positive logic
1: Reverse logic
Ten's digit (VDO2)
0, 1 (same as unit's digit)
Hundred's digit (VDO3)
0, 1 (same as unit's digit)
Thousand's digit (VDO4)
0, 1 (same as unit's digit)
Ten thousand's digit (VDO5)
0, 1 (same as unit's digit)
VDO functions are similar to the DO functions on the control board. The VDO can be used
together with VDIx to implement some simple logic control.
• If VDO function is set to 0, the state of VDO1 to VDO5 is determined by the state of
DI1 to DI5 on the control board. In this case, VDOx and DIx are one-to-one mapping
relationship.
• If VDO function is set to non-0, the function setting and use of VDOx are the same as
DO in group F5.
The VDOx state can be set in A1-21. The application examples of VDIx involve the use of
VDOx, and see the examples for your reference.
Group A2 to A4: Motor 2 to Motor 4 Parameters
The MD380 can switch over the running among four motors. For the four motors, you can:
• Set motor nameplate parameters respectively
• Perform motor parameter auto-tuning respectively
• Select V/F control or vector control respectively
• Set encoder-related parameters respectively
• Set parameters related to V/F control or vector control independently
Groups A2, A3 and A4 respectively correspond to motor 2, motor 3 and motor 4. The
parameters of the three groups are the same. Here we just list the parameters of group A2
for reference.
All parameters in group A2 have the same denition and usage as parameters of motor 1.
For more details, refer to the descriptions of motor 1 parameters.
