Voltage Lower Threshold For Drive Derating Per Cooling Fan Input Voltage Drop
Linear Number: P183
Default Value: 70
Minimum Value: 0
Maximum Value: 100
Access Level: R&D
Read/Write: Read/Write
Modify Level: Online/Offline
This parameter sets the lower voltage threshold for Drive Derating Per Cooling
Fan Input Voltage Drop. If the cooling fan input voltage is lower than this setting,
the maximum output current is limited to the value set in Drive Output Current
Upper Limitation Per Cooling Fan Input Voltage Drop (P185).
Voltage Upper Threshold For Drive Derating Per Cooling Fan Input Voltage Drop
Linear Number: P184
Default Value: 75
Minimum Value: 0
Maximum Value: 100

This parameter sets the upper voltage threshold for Drive Derating Per Cooling
Fan Input Voltage Drop. If the cooling fan input voltage is higher than this
setting, the drive will exit the de-rate operation. This parameter and Vol t a g e
Lower Threshold For Drive Derating Per Cooling Fan Input Voltage Drop (P184)
are the upper and lower limits of the hysteresis controller for drive de-rate caused
by the cooling fan input voltage drop. The maximum output current is limited to
the value set in Drive Output Current Upper Limitation Per Cooling Fan Input
Voltage Drop (P185).
Drive Output Current Upper Limitation Per Cooling Fan Input Voltage Drop
Linear Number: P185
