Abnormal Pulse Control Command; When The Motor Is Running; Serial Communication Error - Delta Electronics ASDA-B Series User Manual

Chapter 10 Troubleshooting|ASDA-B Series
ALE 8 / ALE

: Abnormal pulse control command

Potential Cause
Pulse command
frequency is higher
than rated input
frequency.
ALE 9 / ALE : Excessive deviation

When the motor is running:

Potential Cause
Maximum deviation
parameter setting is too
small.
Torque limit is too low.
There is an overload.
When pulse command is input but the motor does not run or the moving is very slow:
Potential Cause
Gain value is too small. Check for proper gain value.
Torque limit is too low.
There is an overload.
The excessive deviation fault occurs immediately when the pulse command is given:
Potential Cause
Maximum deviation
parameter setting is too
small.
Too much fluctuation of
pulse command.
ALE 10 / ALE

: Serial communication error

Please refer to section 8.3.4 in Chapter 8 for the related error codes.
Potential Cause
Communication
parameter setting is
defective.
Communication
address is incorrect.
Communication value is
incorrect.
10-6
Checking Method
Use pulse frequency detector to measure input
frequency.
Checking Method
Check the maximum deviation parameter
setting and observe the position error value
when the motor is running.
Check torque limit value.
Check for overload condition.
Checking Method
Check torque limit value.
Check for overload condition.
Checking Method
Check the maximum deviation parameter
setting and observe the position error value
when the motor is running.
Check the pulse frequency.
Checking Method
Check the communication parameter setting.
Check the communication address.
Check the communication value.
Corrective Actions
Correctly set the input pulse
frequency.
Corrective Actions
Increases the parameter setting
value of P2-35.
Correctly adjust torque limit value.
Reduce external applied load or re-
estimate the motor capacity.
Corrective Actions
Correctly adjust gain value.
Correctly adjust torque limit value.
Reduce external applied load or re-
estimate the motor capacity.
Corrective Actions
Increases the parameter setting
value of P2-35.
Adjust pulse frequency and
activate filter function (P1-06, P1-
07 and P1-08).
Corrective Actions
Correctly set parameter setting.
Correctly set communication
address.
Correctly set communication value.
