■ L1-04: Motor Overheat Fault Operation Selection (PTC input)
Sets the drive operation when the PTC input signal reaches the motor overheat fault level (oH4).
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

L1-05: Motor Temperature Input Filter Time (PTC input)
Used to set a filter on the PTC input signal in order to prevent a motor overheat fault from being mistakenly detected.
■
L1-13: Continuous Electrothermal Operation Selection
Determines whether or not to hold the current value of the electrothermal motor protection (L1-01) when the power

Setting 0: Disabled
Setting 1: Enabled
■ Motor Protection Using an NTC Thermistor Input
Motor protection is possible for models CIMR-E4A0930 and 4A1200 by connecting the NTC thermistor input in the
motor windings to one of the drive analog input terminals.
This enables the drive to provide torque compensation in response to changes in motor temperature and protect the motor
from overheating.
