■ L1-19: Operation at Thermistor Disconnect (THo) (NTC)
Determines drive operation when a thermistor disconnect fault occurs (THo).
Note: This parameter is available in models CIMR-E4A0930 and 4A1200.
Setting 0: Ramp to stop
The drive stops the motor using the deceleration time1 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.
Setting 3: Alarm only
The operation is continued and a THo alarm is displayed on the digital operator.
■
L1-20: Operation at Motor Overheat (oH5)
Determines drive operation when a motor overheat fault occurs (oH5).
Note: This parameter is available in models CIMR-E4A0930 and 4A1200.
Setting 0: Ramp to stop
The drive stops the motor using the deceleration time1 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.
Setting 3: Alarm only
The operation is continued and an oH5 alarm is displayed on the digital operator.
◆ L2: Momentary Power Loss Ride-Thru
■ 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 be set to
automatically return to the operation it was performing when the power went out based on certain conditions.
Setting 0: Disabled (default)
If power is not restored within 15 ms, a Uv1 fault will result and the drive will stop the motor. The motor coasts to stop.
Setting 1: Recover within L2-02
When a momentary power loss occurs, the drive output will be shut off. Should the power return within the time set to
parameter L2-02, th
e drive will perform Speed Search and attempt to resume operation. If power is not restored within
this time (i.e., DC bus voltage level remains below Uv1 detection level L2-05), then a Uv1 fault is triggered.
