Setting 0: Ramp to Stop
The drive stops the motor using the deceleration time 1 set in parameter C1-02.
Setting 1: Coast to Stop
The drive output is switched off and the motor coasts to stop.
Setting 2: Fast Stop
The drive stops the motor using the Fast Stop time set in parameter C1-09.
n
L1-05: Motor Temperature Input Filter Time (PTC input)
Sets a filter on the PTC input signal to prevent erroneous detection of a motor overheat fault.
No. Name Setting Range Default
L1-05 Motor Temperature Input Filter Time (PTC input) 0.00 to 10.00 s 0.20 s
n
L1-08: oL1 Current Level
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. Name Setting Range Default
L1-08 oL1 Current Level
10 to 150% of drive rated
current
<1>
Determined by
o2-04
<1> 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.
Note: Display is in the following units: 5A0007 to 5A0017: 0.01 A units; 5A0022 to 5A0242: 0.1 A units
n
L1-13: Continuous Electrothermal Operation Selection
Determines whether to hold the current value of the electrothermal motor protection (L1-01) when the power supply is
interrupted.
No. Name Setting Range Default
L1-13 Continuous Electrothermal Operation Selection 0 to 2 1
Setting 0: Disabled
Setting 1: Enabled
Setting 2: Enable Using Real Time Clock (HOA Keypad)
Stores value and integrates (resets) down the oL value based on real time.
u
L2: Momentary Power Loss Ride-Thru
n
L2-01: Momentary Power 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. Name Setting Range Default
L2-01 Momentary Power Loss Operation Selection 0 to 2 2
Setting 0: Disabled
If power is not restored within 15 ms, a Uv1 fault will result and the motor coasts to stop.
Setting 1: Recover within L2-02
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.
Setting 2: Recover as long as CPU Has Power
When a momentary power loss occurs, the drive output will be shut off. If the power returns and the drive control circuit has
power, the drive will attempt to perform Speed Search and resume the operation. This will not trigger a Uv1 fault.
