<1> Default setting is determined by the control mode.
<2> When using PM Open Loop Vector, the default setting is determined by the motor code set to E5-01.
<3> Values shown here are for 200 V class drives. Double values when using a 400 V class unit.
<4> In OLV for PM E1-09 specifies the start frequency for short circuit braking at stop.

Figure 5.40 V/f Pattern
Note: 1.
The following condition must be true when setting up the V/f pattern: E1-09 ≤ E1-07 ≤ E1-06 ≤ E1-11 ≤ E1-04
2.
To make the V/f pattern a straight line set E1-09 = E1-07. In this case the E1-08 setting is disregarded.
3.
E1-03 is unaffected when the drive is initialized using parameter A1-03, but the settings for E1-04 through E1-13 are returned to their
default values.

E2: Motor 1 Parameters
These parameters contain the most important motor data needed for optimal motor control. They are set automatically
when Auto-Tuning is performed. If Auto-Tuning can not be performed, then these parameters can be set manually.
n
E2-01: Motor Rated Current
Set E2-01 to the full load amps (FLA) stamped on the motor nameplate. During Auto-Tuning the value must be entered
to parameter T1-04. If Auto-Tuning completes successfully, the value entered will automatically be saved to E2-01.

Note:
The resolution of E2-01 depends on the rated output power of the drive. If a drive is set up for 7.5 kW rated output power (ND or HD
rating) the value will have two decimal places. It will have one decimal place if a drive is set up for 11 kW and higher.
n
E2-02: Motor Rated Slip
Sets the motor rated slip in Hz. This value is automatically set during Rotational Auto-Tuning.

Depending on
o2-04
If Auto-Tuning can not be performed calculate the motor rated slip using the information written on the motor nameplate
and the formula below:
E2-02 = f - (n x p)/120
(f: rated frequency (Hz), n: rated motor speed (r/min), p: number of motor poles)
n
E2-03: Motor No-Load Current
Set E2-03 to the motor no-load current at rated voltage and rated frequency. If Rotational Auto-Tuning completes
successfully, this value is automatically calculated. If Auto-Tuning can not be performed, contact the motor manufacturer
for information about the no-load current.
