◆ E1-11 Mid Output Frequency B

Setting Range: 0.0 ~ 120.0 Hz

Factory Default: 0.0 Hz

Refer to parameter E1-11 in Appendix A for description details.

◆ E1-12 Mid Output Voltage B

Setting Ranges: 0.0 ~ 255.0 V (240 V Models)

0.0 ~ 510.0 V (480 V Models)

Factory Defaults: 0.0 V (240 V Models)

0.0 V (480 V Models)

Top set up 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

◆ E1-13 Base Voltage

Setting Ranges: 0.0 ~ 255.0 V (240 V Models)

0.0 ~ 510.0 V (480 V Models)

Factory Defaults: 0.0 V (240 V Models)

0.0 V (480 V Models)

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

Figure 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
