3 Alarm Only OH3 Flashes
L01-04 Mtr OH Fault Sel Operation when the motor
temperature analog input (H03-02,
H03-06, or H03-10 = E) exceeds
the OH4 fault level. (2.34V)
0–2 1
0 Decel to Stop
1 Coast to Stop
2 Fast Stop Decel by B05-08
L01-05 Mtr Temp Filter Motor temperature analog input
filter time constant (H03-02, H03-
06, or H03-10 = E)
0.00–10.00 sec 0.20
L01-13 Mtr OL Mem Sel Determines whether or not to hold
the current value of the

L02-01 PwrL Selection Enables/disables the Power Loss
Ride thru function
0–2 0
0 Disabled Drive trips on (Uv1) fault when
power is lost for more than 15
minutes.
1 Enable w/ Timer Recover within the time set in L02-
02. Uv1 will be detected if power
loss is longer than L02-02.
2 Enable if CPU on Recover as long as CPU has
power. Uv1 is not detected.
L02-02 PwrL Ridethru t Power Loss Ride thru time 0.0–25.5 sec **
L02-03 PwrL Baseblock t Output turn on delay after power
resumes
0.1–5.0 sec **
L02-04 PwrL V/F Ramp t Voltage recovery time after speed
search is complete
0.0–5.0 sec **
L02-05 PUV Det Level Under voltage fault detection level 230V: 150–210 VDC
460V: 300–420 VDC
575V: 431–604 VDC
Determined
by E01-01
** Initial value is dependent on drive size, which is determined by O02-04 (kVA Selection).
