Yaskawa CIMR-PU2A0138 [228/548] The drive stops the motor using the deceleration time 1 set in parameter c1 02
The PTC must exhibit the characteristics shown in Figure 5.68 in one motor phase. The motor
overload protection of the drive
expects 3 of these PTCs to be connected in a series.

Figure 5.68 Motor PTC Characteristics
Set up overheat detection using a PTC using parameters L1-03, L1-04, and L1-05 as explained in the following sections.
n
L1-03: Motor Overheat Alarm Operation Selection (PTC input)
Sets the drive operation when the PTC input signal reaches the motor overheat alarm level (oH3).
No. Name Setting Range Default
L1-03 Motor Overheat Alarm Operation Selection (PTC input) 0 to 3 3
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.
Setting 3: Alarm only
The operation is continued and an oH3 alarm is displayed on the digital operator.
n
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).
No. Name Setting Range Default
L1-04 Motor Overheat Fault Operation Selection (PTC input) 0 to 2 1
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
L1-13: Continuous Electrothermal Operation Selection
Determines whether to hold the current value of the electrothermal motor protection (L1-01) when the power supply is
interrupted.
