UP
UP
Under Power
When showing
UP
presents the dc bus voltage is lower the protect level
Check the input power system。
Check the input power voltage fits in the rating of driver。
Check the setting of Pr.084(DCinput voltage is set)is correct or not。
Setting Pr.154 (AMP-Status4 choice(showing Pr.424) = 16(Drive data-DCBus
voltage)
Check the setting of Pr.424(Drive data -DCBus voltage)is correct or not。
OC
OC
Over Current
When showing
OC
presents the output current exceeds the rating of driver
Check if the type of motor fits in the driver’s specification.
Check if the rating of motor’s fits in the rating of driver.
Check if the connection of U, V, and W is properly or not.
Check if the power lines to motor is broken or short with other lines or any defect.
Check if the motor’s wires are short or not.
Check the settings of parameter group BLAC Motor Group are correct or not。
If the
OC
happened in the accelerating period, try to increase the setting (Acc Time).
If the
OC
happened in the decelerating period, try to increase the setting (Dec Time).
If the PID gain is too strong,try to the PID setting。
