• Torque/Speed curve pattern:
• Operating frequency range: 0~Motor rate frequency
• When the motor output torque is not enough and increase F48 setting value.
• When the motor is erratic or vibrates decrease F48 setting value.
• The max. Output torque limit to the inverter is current rated.
• If increase F48 setting value then the output current is too large. Please increase F49 setting value
on the same time.
F49 Slip compensation gain (vector), C14=000
Performance: If the motor load appears too large, increase slip compensation.

• Torque/Speed curve pattern:
• Operating frequency range: 0~motor rated frequency.
• When the motor output rotation speed is too low increase F49 setting value.
• When the motor is erratic or vibrates, decrease F48 setting value.
• The max. output rotation speed limit to the motor max. setting frequency.
• If increase F49 setting value then the output current is too large. Increase F48 setting value at the
same time.
