Programming 53
To set up a custom V/f pattern, program the points shown in the diagram below using parameters E1-04 through E1-13. Be
sure that the following condition is true:
E1-09 ≤ E1-07 ≤ E1-06 ≤ E1-11 ≤ E1-04
Fig.38 Custom V/f Pattern Programming Curve
Increasing the voltage in the V/f pattern increases the available motor torque. However, when setting a custom V/f pattern,
increase the voltage gradually while monitoring the motor current, to prevent:
• Drive faults as a result of motor over-excitation
• Motor overheating or excessive vibration
