Drive 20
ER-10 : TLV (DC-Link Low Voltage Trip)
Cause
ㆍ
Occurs when the power supply voltage is low.
ㆍ
Occurs when the connected load is larger than the power capacity.
Action
ㆍ
Check the drive input voltage.
ㆍ
Check the power capacity.
※
Check the DC Link voltage (Drive 45) on the main LCD Screen.
ER-11 : TOV (DC-Link High Voltage Trip)
Cause
ㆍ
Occurs when the deceleration time (Drive 19) is short compared to the load inertia
ㆍ
Occurs when the drive input voltage is too high.
Action
ㆍ
increase the deceleration time (Drive 20).
ㆍ
Check the driver power supply voltage
※
Check the DC Link voltage (Drive 45) on Parameter Settings.
ER-13 : TDOL (Drive Over-load Trip)
Cause
ㆍ
Occurs when the load is larger than the rated capacity of the Drive.
Action
ㆍ
Use a larger capacity Drive for the load.
ER-12 : TOL(Motor Over-Load Trip))
Cause
ㆍ
It alerts and stops operation to protect the motor when the load is above the overload trip level (Drive 22)
of the rated current of the motor and the motor operates for more than overload trip time (Drive 23).
EX) If the rated current of the motor is 10[A], the overload trip level is 120%, and the overload trip time
is 5 seconds, It makes a trip when the pump operates above 12[A] of output current for more than
5 seconds.
Action
ㆍ
Check the rated current of the motor (on the nameplate) and the rated current setting (Drive 12).
※
It is possible to check the output current on the main LCD screen.
