Description
Sets the d-Axis current reference when running a high load at constant speed.
Set as a percentage of the motor rated current.
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.
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.
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.
0: Disabled. Disable when using an SPM motor.
1: Enabled. Use this setting to enhance the speed control range when using an
IPM motor.
Prevents output voltage saturation. Should be set just below the voltage
provided by the input power supply.
Sets the gain used for internal speed feedback detection during ov suppression. Default: 1.50
Sets the proportional gain for PLL control of an extended observer. There is
normally no need to change this parameter from the default value.
Sets the current to determine polarity for the initial polarity calculation as a
percentage of the motor rated current.
100% = Motor rated current
