V/f OLV/PM OLV/PM EZOLV
Sets the function to enable and disable ground fault protection.
0 : Disabled
1 : Enabled
V/f OLV/PM OLV/PM EZOLV
Sets operation of the heatsink cooling fan.
0 : During Run, w/ L8-11 Off-Delay
1 : Always On
2 : On when Drive Temp Reaches L8-64
V/f OLV/PM OLV/PM EZOLV
Sets the length of time that the drive will wait before it stops the cooling fan after it cancels
the Run command when L8-10 = 0 [Heatsink Fan Operation Selection = During Run, w/
L8-11 Off-Delay].
V/f OLV/PM OLV/PM EZOLV
Sets the ambient temperature of the drive installation area.
Note:
The setting range changes when the L8-35 [Installation Method Selection] setting
changes.
• When L8-35 = 0 or 2 [IP20/UL Open Type or IP20/UL Type 1]: -10 °C～+60 °C
• When L8-35 = 1 or 3 [Side-by-Side Mounting or IP55/UL Type 12]: -10 °C～+50 °C
V/f OLV/PM OLV/PM EZOLV
Sets the function to decrease drive overload at low speeds to prevent damage to the main
circuit transistor during low speed operation (at 6 Hz or slower) to prevent oL2 [Drive
Overloaded].
Note:
Contact Yaskawa or your nearest sales representative before disabling this function at
low speeds. If you frequently operate drives with high output current in low speed
ranges, it can cause heat stress and decrease the life span of drive IGBTs.
0 : Disabled (No Additional Derate)
1 : Enabled (Reduced oL2 Level)
V/f OLV/PM EZOLV OLV/PM
Set the software current limit selection function to prevent damage to the main circuit
transistor caused by too much current.
0 : Disabled
1 : Enabled
V/f OLV/PM EZOLV OLV/PM
Sets the ratio at which the drive derates the frequency reference during an oH alarm.
V/f OLV/PM OLV/PM EZOLV
Sets the PM motor overcurrent detection level as a percentage of the motor rated current
value.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor
rated current.
• A1-02 ≠ 8 [EZOLV]: E5-03 [Motor Rated Current (FLA)]
• A1-02 = 8: E9-06 [Motor Rated Current (FLA)]
V/f OLV/PM OLV/PM EZOLV
Sets the function to detect LF2.
0 : Disabled
1 : Enabled
V/f OLV/PM OLV/PM EZOLV
Sets the LF2 [Output Current Imbalance] detection time.
V/f OLV/PM EZOLV OLV/PM
Sets the type of drive installation.
0 : IP20/UL Open Type
1 : Side-by-Side Mounting
2 : IP20/UL Type 1
3 : IP55/UL Type 12
V/f OLV/PM OLV/PM EZOLV
Sets the carrier frequency reduction function. The drive decreases the carrier frequency
when the output current is more than a specified level.
1 : Enabled below 6 Hz
2 : Enabled for All Speeds
3 : Enable at Overload
