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. Reduce this setting if oscillation occurs at start.
V/f V/f w/PG
OLV/PM AOLV/PM
For large inertia loads or to increase the speed control response, increase this setting. Too high
of a setting when driving a very light load or load with very low inertia can result in oscillation.
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
All Modes
Selects the content of the last monitor that is shown when scrolling through Drive Mode
display. Enter the last three digits of the monitor parameter number to be displayed: U -
All Modes
1: Frequency reference (U1-01)
2: Direction
3: Output frequency (U1-02)
4: Output current (U1-03)
5: User-selected monitor (set by o1-01)
All Modes
Sets the units the drive should use to display the frequency reference and motor speed monitors.
0: 0.01 Hz
1: 0.01% (100% = E1-04)
2: r/min (calculated using the number of motor poles setting in E2-04, E4-04, or E5-04)
3: User-selected units (set by o1-10 and o1-11)
V/f V/f w/PG
OLV/PM AOLV/PM
0: Hz
1: r/min
All Modes
These settings define the display values when o1-03 is set to 3.
o1-10 sets the display value that is equal to the maximum output frequency.
o1-11 sets the position of the decimal position.
