Err-16_ Excessive Deviation; Err-18_ Torque Overload Alarm - BONMET SDL10A User Manual

Communication error caused
by interference

8.2.16 Err-16_ Excessive deviation

Probable causes
Maximum deviation
parameter setting is too small
Gain value is too small
Torque limit is too low
Machine failure
Input pulse command over
frequency
Incorrect electric gear ratio
setting

8.2.17 Err-18_ Torque overload alarm

Probable causes
Maximum overload testing
parameter setting is too small
Machine failure
The drive has exceeded its
rated load during continuous
operation.
The wiring of drive and
encoder is in error
Check the digital input status through monitor
function
Conforming method
Check the maximum deviation parameter
setting and observe the position error value
when the motor is running
Check for proper gain value
Check torque limit value
Check the mechanical connection
Check the input pulse frequency whether it is
over 500kHz
Check the input pulse frequency whether it is
over 500kHz after set the electric gear ratio
Conforming method
Check the maximum overload testing parameter
setting
Check the mechanical connection
Check if the drive is overloaded by monitoring
the motor torque, 100% or less continuous
motor output torque is OK
Check the wiring of U, V, W and encoder

① Separate the encoder cable and the power
cable if they are bound together
② Use shielded twisted wire
Measures
Increases the parameter setting value of Pn-55
Correctly adjust gain value
Correctly adjust torque limit value
Improve the mechanical transmission parts
Reduce the pulse frequency.
Reduce the ratio.
Measures
Increases the parameter setting value of Pn-22,
usually we suggest customer to set it under 150.
Improve the mechanical transmission parts
Increase motor capacity or reduce load
Ensure all wiring is correct
