13-5
External device error Replace with a new device.
Hardware error
If the AnL error still occurs after checking all the wiring, send the drive back to
the factory for repair.
ID No. Display on LCM Keypad Warning Name Description
13
Under current (uC) Low current
Action and Reset
Action level Pr.06-71
Action time Pr.06-72
Warning treatment parameter
Pr.06-73
0: No function
1: Warn and coast to stop
2: Warn and ramp to stop by 2
nd
deceleration time
3: Warn and continue operation
Reset method
Auto
“Warning” occurs when Pr.06-73=3. The “Warning” automatically
clears when the output current is > (Pr.06-71+0.1 A).
Manual “Error” occurs when Pr.06-73=1 and 2. You must reset manually.
Reset condition Immediately reset
Record Does not record when Pr.06-73=3 and uC displays “Warning”.
Cause Corrective Actions
Broken motor cable Exclude the connection issue of the motor and its load.
Improper setting for the low current
protection
Set the proper settings for Pr.06-71, Pr.06-72 and Pr.06-73.
Low load
Check the loading status.
Make sure the loading matches the motor capacity.
ID No. Display on LCM Keypad Warning Name Description
20 Over-torque 1 (ot1) Over-torque 1 warning
Action and Reset
Action level Pr.06-07
Action time Pr.06-08
Warning treatment parameter
Pr.06-06=1 or 3
0: No function
1: Continue operation after over-torque detection during constant speed
operation
2: Stop after over-torque detection during constant speed operation
3: Continue operation after over-torque detection during RUN
4: Stop after over-torque detection during RUN
Reset method When input current < (Pr.06-07 – 5%), the Ot1 warning automatically clears.
Reset condition When input current < (Pr.06-07 – 5%), the Ot1 warning automatically clears.
Record N/A
Cause Corrective Actions
Incorrect parameter setting Configure the settings for Pr.06-07 and 06-08 again.
Mechanical error (e.g. mechanical
lock due to over-torque)
Remove the causes of malfunction.
The load is too large.
Decrease the loading.
Replace with a motor with larger capacity.
Accel./ Decel. time and working
cycle is too short.
Increase the setting values for Pr.01-12–01-19 (accel./ decel. time).
V/F voltage is too high.
Adjust the settings for Pr.01-01–01-08 (V/F curve), especially the setting value
for the mid-point voltage (if the mid-point voltage is set too small, the load
capacity decreases at low-speed).
The motor capacity is too small. Replace with a motor with larger capacity.
Over-load during low-speed
operation.
Decrease the loading during low-speed operation.
Increase the motor capacity.
The torque compensation is too
large.
Readjust the torque compensation value (Pr.07-26 torque compensation gain)
till the output current decreases and the motor does not stall.
