5-4 DVP-MC operating manual
Input Point LED
There are 8 input-point LED indicators (I0~I7) for showing if DVP10MC11T digital input point is on- state or
off-state.
Input point LED state Indication
Green light on(I0~I7) Input point is on-state.
Light off(I0~I7) Input point is off-state.
Output Point LED
There are 4 output-point LED indicators (Q0~Q3) for showing if DVP10MC11T digital output point is on-state
or off-state.
Output point LED state Indication
Green light on(Q0~Q3) Output point is on-state.
Light off(Q0~Q3) Output point is off-state.
5.2. Status Word Instruction
When an error emerges in MC module of DVP10MC11T, user could judge the error cause according to the
values of D6511 and D6512. The indication of each bit of D6511 and D6512 is shown below.
Bit
device
Indication when the value of each
bit of D6511 is 1.
How to deal with
Bit0
MC module is in error mode;
The running motion control
program is terminated
Press “Reset" key to restart DVP10MC11T.
Bit1
The configuration data is being
downloaded to MC module by the
PC.
No correction is needed and DVP10MC11T will
resume to run after download is finished.
Bit2
Node list is empty and no slave is
configured.
Via CANopen Builder, add the slave into the node
list of MC module and re-download.
Bit3
The current configuration data is
invalid.
Check if there is any error in configuration data;
redownload it after configuration data is modified.
Bit4
Buffer area sending the data is
full.
1. Check if CANopen bus connection is normal.
2. Check if the baud rates of master and slave of
CANopen bus are same.
3. Check if the terminal resistors are connected to
the two ends of CANopen bus.
Bit5
Buffer area receiving the data is
full.
1. Check if CANopen bus connection is normal.
2. Check if the baud rates of master and slave of
CANopen bus are same.
3. Check if the terminal resistors are connected to
the two ends of CANopen bus.
Bit6 Power supply is insufficient. Check if 24V power supply is normal.
Bit7
The internal memory operation
error
After power on once again, return it to factory for
repair if the error still exists.
