Section L: Protection Parameters
L8 Hardware Protection
Input phase loss detection is disabled in the following cases:
• A Stop command is input
• Magnetic Contact (MC) shuts OFF
• CPU A/D converter fault (CPF5)
• During deceleration
• Output current
≤
30% of Inverter rated current
This parameter detects the inverter output open-phase.
An open phase condition may be erroneously detected at the output if inadequate
motor capacity is applied to the inverter, or the load torque is low.
The ground fault detection circuit monitors the output current and activates when
excessive ground current is detected.
A ground fault will occur when the inverter output grounding current has exceeded
50% of the inverter rated current.

1 Inverter output open-phase detection is enabled.
L8-10 Ground Fault Protection A
Setting Description
0 Ground fault detection is disabled
1
Ground fault detection is enabled.(factory
default).
