Description
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Selects the speed estimation method. Usually it is not necessary to change this setting.
0 : Method 1
1 : Method 2
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Set n8-48 [Pull-in/Light Load Id Current] to the percentage of load current (q-axis
current) that you will apply, where E5-03 [Motor Rated Current (FLA)] = a setting
value of 100%.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Set n8-78 [Medium Load Id Current] to the percentage of load current (q-axis current)
that you will apply, where E5-03 [Motor Rated Current (FLA)] = a setting value of
100%.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Set n8-49 [Heavy Load Id Current] to the percentage of load current (q-axis current)
that you will apply, where E5-03 [Motor Rated Current (FLA)] = a setting value of
100%.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the level of the pull-in current as a percentage, where E5-03 [PM Motor Rated
Current (FLA)] = 100%.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the pull-in current that can flow during deceleration as a percentage of the E5-03
[PM Motor Rated Current (FLA)].
Note:
When n8-79 = 0, the drive will use the value set in n8-51 [Pull-in Current @
Acceleration].
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the current that the drive uses to estimate the initial motor magnetic pole as a
percentage where E5-03 [PM Motor Rated Current (FLA)] = 100%.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the method of output voltage limit. If there is vibration in the constant output
range, set Feedforward Method. Usually it is not necessary to change this setting.
0 : Feedback Method
1 : Feedforward Method
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the current level at which output voltage limit sequence selection occurs as a
percentage where the motor rated current is 100%. Normally there is no need to change
this setting.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor
rated current.
• A1-02 = 5, 6 [OLV/PM, AOLV/PM]: E5-03 [PM Motor Rated Current (FLA)]
• A1-02 = 8[EZOLV]: E9-06 [PM Motor Rated Current (FLA)]
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the hysteresis width of the current level at which output voltage limit sequence
selection occurs as a percentage where the motor rated current is 100%. Normally there
is no need to change this setting.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the motor
rated current.
• A1-02 = 5, 6 [OLV/PM, AOLV/PM]: E5-03 [PM Motor Rated Current (FLA)]
• A1-02 = 8[EZOLV]: E9-06 [PM Motor Rated Current (FLA)]
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the speed level at which output voltage limit sequence selection occurs as a
percentage where the maximum output frequency is 100%. Usually it is not necessary to
change this setting.
Note:
Parameter A1-02 [Control Method Selection] selects which parameter is the
maximum output frequency.
• A1-02 = 5, 6 [OLV/PM, AOLV/PM]: E1-04 [Maximum Output Frequency]
• A1-02 = 8: E9-02 [Motor Max Revolutions]
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the limit value of feedback output voltage limit Id operation. Enabled when n8-87
= 0 [Output Voltage Control Selection = Speed Feedback Form]. Usually it is not
necessary to change this setting.
