A2
ASDA-
: Full closed-loop excessive deviation
Potential Cause
The position control
deviation value of
full-closed loop
exceeds the
specified limit.
Maximum deviation
parameter setting is
too small.
: Linear scale wiring error
Potential Cause
The wiring
connections of
linear scale and
servo drive are in
error.
: Analog input voltage error
Potential Cause
The analog input
voltage is higher
than the value of P1-
83 over 50ms.
: DSP firmware upgrade
Potential Cause
EE-PROM is not reset
after the firmware
version is upgraded.
10-18
Checking Method
1. Check if the setting value of P1-73 is
too small.
2. Check if all connections are tight and
well-connected to the mechanical
equipment.
Checking Method
Check if communication circuit and
wiring connections of linear scale are not
correct.
Checking Method
Check if analog input voltage is too high.
Checking Method
Check if EE-PROM is reset after the
firmware version is upgraded.
Chapter 10 Troubleshooting
Corrective Actions
1. Increases the parameter
setting value of P1-73.
2. Ensure all connections are
tight and well-connected to
the mechanical equipment.
Corrective Actions
Check all wiring connections
of linear scale and reconnect
the wiring if necessary.
Corrective Actions
Check all analog input
voltages. Check if there is any
question about the sources of
analog speed commands.
Corrective Actions
Set P2-08 to 30 first, and then
28 next, and restart the servo
drive.
