Setting a Custom V/f Pattern
Setting parameter E1-03 to “F” allows to set up a custom V/f pattern by changing parameters E1-04 to E1-13.
When E1-03 is changed to “F”, the default values for parameters E1-04 to E1-13 will be equal to V/f pattern 1 of the predefined
patterns.
n V/f Pattern Settings E1-04 to E1-13
Using parameters E1-04 through E1-13, the user can either monitor the V/f pattern values if E1-03 =< 15 or set up a custom
V/f pattern as shown in Figure 5.42 when E1-03 = F.

<1> Default setting is determined by the control mode.
<2> Values shown are for 200 V class drives; double the value when using 400 V class drives.
<3> In OLV for PM E1-09 specifies the start frequency for short circuit braking at stop.
Refer to b2-13: Short Circuit Brake Time at Stop on page
129 for details.
<4> When E1-13 is set to 0.0 V, the drive uses the value set in E1-05 to control the voltage.
<5> Default setting is determined by E5-01 in OLV/PM. When E5-01 is set to FFFFH, the setting range for E1-04 and E1-06 is 10.0 to 40.0 Hz and the
setting range for E1-09 is 0.0 to 400.0 Hz.
