n L1-04: Motor Overheat Fault (oH4) Operation Selection
Sets the drive operation when the PTC input signal reaches the motor overheat fault level. (PTC input level: Tr + 5 °C)
No.
L1-04
Setting 0: Ramp to Stop
The drive stops the motor using the active deceleration time.
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
Used to set a filter on the PTC signal in order to prevent a motor overheat fault from being mistakenly detected.
No.
L1-05
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.
L1-13 Continuous Electrothermal Operation Selection
Setting 0: Disabled
Setting 1: Enabled
n L1-22: Leakage Current Filter Time Constant 1
Note: 1. Available in drive software versions PRG: 1021 and later.
2. Available only when C6-02 is set to B. To display this parameter, first set C6-02 to B.
Sets the time constant for the filter applied to motor overload detection current or monitor current for constant speed operation.
Leakage current can incorrectly trigger motor overload fault oL1 or result in incorrect monitor reading. Increase this setting
if erroneous detection occurs or if the monitor display is incorrect.
NOTICE: Setting parameter L1-22 too high may cause the drive to detect motor overload too slowly and burn out the motor. Be sure to set
L1-22 to an appropriate value for the application.
No.
L1-22
n L1-23: Leakage Current Filter Time Constant 2
Note: 1. Available in drive software versions PRG: 1021 and later.
2. Available only when C6-02 is set to B. To display this parameter, first set C6-02 to B.
Sets the time constant for the filter applied to monitor current during acceleration and deceleration. Leakage current can result
in incorrect monitor reading. Increase this setting if the monitor display is incorrect.
Note: Setting parameter L1-23 too high may cause the current monitor to take too long to read the initial current level. Check the operation sequence
being used if this is a problem.
No.
