Description
V/f CL-V/f OLV CLV AOLV
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 [PM Motor Rated Current (FLA)]
• A1-02 = 8: E9-06 [Motor Rated Current (FLA)]
V/f CL-V/f OLV CLV AOLV
Sets the function to detect LF2 [Output Current Imbalance].
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the LF2 [Output Current Imbalance] detection time.
V/f CL-V/f OLV CLV AOLV
Sets the type of drive installation.
0 : IP20/UL Open Type/Ex Heatsink
1 : Side-by-Side Mounting
2 : IP20/UL Type 1
3 : Finless
V/f CL-V/f OLV CLV AOLV
Sets the carrier frequency reduction function. The drive reduces the carrier frequency when
the output current is more than a specified level.
0 : Disabled
1 : Enabled below 6 Hz
2 : Enabled for All Speeds
V/f CL-V/f OLV CLV AOLV
Sets the length of time until the automatically reduced carrier frequency returns to the
condition before the reduction.
V/f CL-V/f OLV CLV AOLV
Sets the function to cause an HCA [Current Alarm] when the output current is more than
150% of the drive rated current.
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the STPo [Motor Step-Out Detected] detection level as a percentage of the motor
rated current.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor
rated current.
• A1-02 = 5 [OLV/PM]: E5-03 [PM Motor Rated Current (FLA)]
• A1-02 = 8 [EZOLV]: E9-06 [Motor Rated Current (FLA)]
V/f CL-V/f OLV CLV AOLV
Sets the detection level for STPo [Motor Step-Out Detected] related to the ACR integral
value.
V/f CL-V/f OLV CLV AOLV
Sets the length of time until the drive detects STPo after it is more than the value of L8-51
[STPo I Detection Level].
V/f CL-V/f OLV CLV AOLV
Sets the Id deviation detection function for STPo [Motor Step-Out Detected].
0 : Disabled
1 : Enabled
V/f CL-V/f OLV CLV AOLV
Sets the protection function for the internal braking transistor.
0 : Disable
1 : Protection Enabled
V/f CL-V/f OLV CLV AOLV
Sets the length time that the acceleration stall prevention function can continue to operate
before the drive detects an STPo [Motor Step-Out Detected].
V/f CL-V/f OLV CLV AOLV
Sets the number of times the acceleration stall prevention function can operate until speeds
agree before the drive detects an STPo [Motor Step-Out Detected].
