Yaskawa CIMR-PU2A0360 [248/548] Enables or disables the software current limit cla protection function to prevent main circuit transistor failures caused by high current
Setting 1: Run always
The fan runs when power is supplied to the drive.
n
L8-11: Heatsink Cooling Fan Off-Delay Time
Sets the cooling fan switch off-delay time if parameter L8-10 is set to 0.
No. Name Setting Range Default
L8-11 Heatsink Cooling Fan Off-Delay Time 0 to 300 s 60 s
n
L8-12: Ambient Temperature Setting
Automatically
adapts the drive rated current to safe
values when used with parameter L8-35. This eliminates the need to reduce
the drive rated current when the temperature where the drive is mounted is above the specified values. Refer to Temperature
Derating on page 389 for details.
No. Name Setting Range Default
L8-12 Ambient Temperature Setting -10 to +50 °C 40 °C
n
L8-15: oL2 Characteristics Selection at Low Speeds
Selects whether the drive overload capability (oL fault detection level) is reduced at low speeds to prevent premature output
transistor failures.
Note: Contact Yaskawa for consultation before disabling this function. Disabling this function may shorten the operating life of the power
transistors.
No. Name Setting Range Default
L8-15 oL2 Characteristics Selection at Low Speed 0, 1 1
Setting 0: Protection Disabled at Low Speed
The overload protection level is not reduced. Frequently operating the drive with high output current at low speed can lead to
premature drive faults.
Setting 1: Protection Enabled at Low Speed
The overload protection level (oL2 fault detection level) is automatically reduced at speeds below 6 Hz. At zero speed, the
overload is derated by 50%.
n
L8-18: Software Current Limit Selection
Enables or disables the Software Current Limit (CLA) protection function to prevent main circuit transistor failures caused
by high current.
Note: Do not change this setting unless absolutely necessary. Leave the Software CLA enabled for proper drive protection and operation.
No. Name Setting Range Default
L8-18 Software Current Limit Selection 0, 1 0
Setting 0: Software CLA Disabled
The drive may trip on an oC fault if the load is too heavy or the acceleration is too short.
Setting 1: Software CLA Enabled
When the Software CLA current level is reached, the drive reduces the output voltage to reduce the current. Normal operation
continues when the current level drops below the Software CLA level.
n
L8-32: Main Contactor and Cooling Fan Power Supply Failure Selection
Determines drive operation when a FAn fault occurs.
No. Name Setting Range Default
L8-32 Main Contactor and Cooling Fan Power Supply Failure Selection 0 to 4 1
Setting 0: Ramp to stop
The drive stops the motor using the deceleration time set in parameter C1-02.
Setting 1: Coast to stop
The drive output is switched off and the motor coasts to a stop.
