All Modes
Sets stopping method when the motor temperature analog input (H3-02, H3-06, or H3-10 = E)
exceeds the oH4 fault level.
0: Ramp to stop
1: Coast to stop
2: Fast Stop (decelerate to stop using the deceleration time in C1-09)
All Modes
Adjusts the filter for the motor temperature analog input (H3-02, H3-06, or H3-10 = E).
All Modes
0: Disabled
1: Enabled
All Modes
0: Disabled. Drive trips on (Uv1) fault when power is lost during Run.
1: Recover within the time set in L2-02. Uv1 will be detected if power loss is longer than L2-02.
2: Recover as long as CPU has power. Uv1 is not detected.
All Modes
Sets the Power Loss Ride-Thru time. Enabled only when L2-01 = 1 or S4-01 = 2.
All Modes
Sets the minimum wait time for residual motor voltage decay before the drive output
reenergizes after performing Power Loss Ride-Thru.
Increasing the time set to L2-03 may help if overcurrent or overvoltage occur during Speed
Search or during DC Injection Braking.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time for the output voltage to return to the preset V/f pattern during Speed Search.
All Modes
Sets the DC bus undervoltage trip level.
V/f V/f w/PG
OLV/PM AOLV/PM
0: Disabled.
1: General purpose. Acceleration is paused as long as the current is above the L3-02 setting.
2: Intelligent. Accelerate in the shortest possible time without exceeding the L3-02 level.
Note: Setting 2 is not available when using OLV/PM.
V/f V/f w/PG
OLV/PM AOLV/PM
Used when L3-01 = 1 or 2. 100% is equal to the drive rated current.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets Stall Prevention lower limit during acceleration when operating in the constant power
range. Set as a percentage of the drive's rated current.
All Modes
0: Disabled. Deceleration at the active deceleration rate. An ov fault may occur.
1: General purpose. Deceleration is paused when the DC bus voltage exceeds the Stall
Prevention level.
2: Intelligent. Decelerate as fast as possible while avoiding ov faults.
3: Stall Prevention with braking resistor. Stall Prevention during deceleration is enabled in
coordination with dynamic braking.
4: Overexcitation Deceleration 1. Decelerates while increasing the motor flux.
5: Overexcitation Deceleration 2. Adjust the deceleration rate according to the DC bus voltage.
