■
S4-05: Rescue Operation Torque Limit
Sets a time limit for Light Load Direction Search.
No.
S4-05
■
S4-06: Rescue Operation Power Supply Selection
Specifies the type of backup power supply the drive should switch to when the power goes out.
No.
S4-06
0: Battery
1: UPS (single-phase)
2: UPS (three-phase)
■
S4-07: UPS Power
Sets the capacity of the UPS.
No.
S4-07
■
S4-08: UPS Operation Speed Limit Selection
Determines how a speed limit should be applied to the Rescue Operation speed (d1-25) when operating from a UPS. The
drive calculates the appropriate speed limit based on the UPS capacity set in S4-07. This speed limit helps prevent voltage
saturation and motor stall during Rescue Operation.
No.
S4-08
0: Disabled
1: Enabled until Light Load Direction Search is complete
2: Enabled until stop
■
S4-12: DC Bus Voltage during Rescue Operation
Sets the DC bus voltage during Rescue Operation.
No.
S4-12
■
S4-13: Rescue Operation Power Supply Deterioration Detection Level
Determines at which level of backup power supply deterioration a PF5 fault is triggered. The following conditions will
trigger PF5:
• During Rescue Operation, DC bus voltage < [S4-12 × (S4-13 - 10%)]
• 100 ms after Rescue Operation has been triggered, the DC bus voltage does not rise above S4-12 × S4-13 before the
motor starts
No.
