Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the low-pass filter shut-off frequency for high frequency injection.
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-
57 = 1 [HFI Overlap Selection = Enabled] to enable this parameter.
• The drive automatically calculates this value when High Frequency Injection
Auto-Tuning completes successfully.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the response gain for the high frequency injection speed estimation.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the integral time constant for the high frequency injection speed estimation.
Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the internal speed feedback detection reduction unit gain as a magnification value.
Usually it is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the time constant the drive uses to align the pull-in current reference value with the
actual current value. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
On the basis that parameter E5-03 [Motor Rated Current (FLA)] is the 100% value, this
parameter sets the d-axis current that flows to the motor during run at constant speed as
a percentage.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the d-axis current to that the drive will supply to the motor to run it at a constant
speed with a heavy load. Considers E5-03 [PM Motor Rated Current (FLA)] to be
100%. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the load current level at which heavy load control starts where E5-03 [Motor Rated
Current (FLA)] is 100%. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the pull-in current allowed to flow during acceleration/deceleration 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 [Motor Rated Current (FLA)]
• A1-02 = 8 [EZOLV]: E9-06 [Motor Rated Current (FLA)]
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the time constant that the drive uses when adjusting for voltage errors.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the ratio between motor inertia and machine inertia.
0 : Below 1:10
1 : Between 1:10 and 1:30
2 : Between 1:30 and 1:50
3 : Beyond 1:50
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the function that detects motor speed with high frequency injection.
Note:
When you set n8-57 = 1, doHigh Frequency Injection Auto-Tuning.
0 : Disabled
1 : Enabled
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the output voltage limit to prevent saturation of the output voltage. Usually it is not
necessary to change this parameter.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the proportional gain for output voltage control. Usually it is not necessary to
change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the gain of internal speed feedback detection suppression while the overvoltage
suppression function is operating as a magnification value. Usually it is not necessary to
change this parameter.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Usually it is not necessary to change this setting. Sets the Proportional gain that the
drive uses for speed estimation.
