1 8 L Protection Functions
Settin amp to Stop
The drive stops the motor using the deceleration time 1 set in parameter C1-02.
Settin 1 Coast to Stop
The drive output is switched off and the motor coasts to stop.
Settin 2 Fast Stop
The drive stops the motor using the Fast Stop time set in parameter C1-09.
L1 Motor emperature Input Filter ime (P C input)
Sets a filter on the PTC input signal to prevent erroneous detection of a motor overheat fault.
No
L1-05 Motor Temperature Input Filter Time (PTC input)
L1 8 oL1 Current Le el
Sets the reference current for motor thermal overload detection for the motor in amperes. When L1-08 is set to 0.0 A (default),
parameter E2-01 (E5-03 in PM control) is used as the reference for motor overload protection. When L1-08 ≠0.0 A, the set
value is used as the reference for motor overload protection.
No
L1-08
<1> The number of decimal places in the parameter value depends on the drive model. This value has two decimal places (0.01 A) if the drive is set for
a maximum applicable motor capacity up to and including 11 kW, 2A0031, 4A0021 (input voltage of 460 V or higher) or 4A0027 (input voltage
of lower than 460 V) and one decimal place (0.1 A) if the maximum applicable motor capacity is higher than 11 kW, 2A0046, 4A0027 (input voltage
460 V or higher) or 4A0034 (input voltage lower than 460 V).
<2> Cannot be set to a value smaller than 10% of drive rated current when the current level is set to a value greater than 0.0 A.
L1 1 Continuous Electrot ermal Operation Selection
Determines whether to hold the current value of the electrothermal motor protection (L1-01) when the power supply is
interrupted.
No
L1-13
Settin Disabled
Settin 1 Enabled
Settin 2 Enable Usin
Stores value and integrates (resets) down the oL value based on real time.
L2 Momentary Po er Loss ide
L2 1 Momentary Po er Loss Operation Selection
When a momentary power loss occurs (DC bus voltage falls below the level set in L2-05), the drive can automatically return
to the operation it was performing prior to the power loss based on certain conditions.
No
L2-01
Settin Disabled
If power is not restored within 15 ms, a Uv1 fault will result and the motor coasts to stop.
Settin 1 eco er it in L2 2
When a momentary power loss occurs, the drive output will be shut off. If the power returns within the time set to parameter
L2-02, the drive will perform Speed Search and attempt to resume operation. If the power does not return within this time, it
will trigger a Uv1 fault.
