V/f V/f w/PG
OLV/PM AOLV/PM
There is normally no need to change this parameter from the default value.
Sets the frequency in Hz for the superimposed signal used for superimposed harmonics.
Enabled when n8-57 = 1.
Note: This parameter is not available with models CIMR-A4A0930 and 4A1200.
V/f V/f w/PG
OLV/PM AOLV/PM
There is normally no need to change this parameter from the default value.
Sets the amplitude for High Frequency Injection as a percentage of the voltage when the voltage
class base is 100% (200 V Class is 200 V and, 400 V Class is 400 V). Adjust this value when
there is too much or too little current as a result of the settings assigned to motor parameters.
Enabled when n8-57 = 1.
Note: This parameter is not available with models CIMR-A4A0930 and 4A1200.
V/f V/f w/PG
OLV/PM AOLV/PM
There is normally no need to change this parameter from the default value.
Sets the cutoff frequency of a low pass filter for high frequency injection. Enabled when n8-57
= 1.
Note: This parameter is not available with models CIMR-A4A0930 and 4A1200.
V/f V/f w/PG
OLV/PM AOLV/PM
Increase this setting if hunting occurs. Decrease to lower the response.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the time constant to make the pull-in current reference and actual current value agree.
Decrease the value if the motor begins to oscillate, and increase the value if it takes too long for
the current reference to equal the output current.
V/f V/f w/PG
OLV/PM AOLV/PM
Defines the d-axis current reference during no-load operation at a constant speed. Set as a
percentage of the motor rated current. Increase this setting if hunting occurs while running at
constant speed.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the d-axis current reference when running a high load at constant speed. Set as a percentage
of the motor rated current.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the d-axis current reference during acceleration/deceleration as a percentage of the motor
rated current. Set to a high value when more starting torque is needed.
V/f V/f w/PG
OLV/PM AOLV/PM
Adjusts the value when hunting occurs at low speed. If hunting occurs with sudden load
changes, increase n8-54 in increments of 0.1. Increase this setting if vibration occurs at start.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the ratio between motor 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 V/f w/PG
OLV/PM AOLV/PM
0: Disabled. Disable when using an SPM motor.
1: Enabled. Use this setting to enhance the speed control range when using an IPM motor.
V/f V/f w/PG
OLV/PM AOLV/PM
Prevents output voltage saturation. Should be set just below the voltage provided by the input
power supply.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the gain used for internal speed feedback detection during ov suppression
