Figure 4.22 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 below E1-06, set E1-09 equal to E1-07. In this case the E1-08 setting is disregarded.
3. E1-03 is unaffected when the drive is initialized, but E1-04 through E1-13 return to their default values.
4. Only use E1-11, E1-12, and E1-13 to fine-tune the V/f pattern in the constant output range. These parameters rarely need to be changed.
n E2-01: Motor Rated Current
Provides motor control, protects the motor, and calculates torque limits. Set E2-01 to the full load amps (FLA) stamped on
the motor nameplate. If Auto-Tuning completes successfully, the value entered to T1-04 will automatically be saved to E2-01.
No. Parameter Name Setting Range Default
E2-01 Motor Rated Current
10% to 150% of the drive
rated current <1>
Determined by
o2-04
<1> Display is in the following units:
2o0028, 2o0042, and 4o0011 to 4o0027: 0.01 A units
2o0054 to 2o0248 and 4o0034 to 4o0414: 0.1 A units
Note: An oPE02 error will occur if the motor rated current in E2-01 is set lower than the motor no-load current in E2-03. Set E2-03 correctly to
prevent this error.
n E2-11: Motor Rated Power
Sets the motor rated power in kW. If Auto-Tuning completes successfully, the value entered to T1-02 will automatically be
saved to E2-11.
No. Parameter Name Setting Range Default
E2-11 Motor Rated Power 0.00 to 650.00 kW
Determined by
o2-04
n E5-01: Motor Code Selection (for PM Motors)
When using Yaskawa motors, set the motor code for the PM motor being used. The drive automatically sets several parameters
to appropriate values depending on the motor code.
Setting parameter E5-01 to FFFF allows the motor data to be manually set using the E5-oo parameters.
No. Parameter Name Setting Range Default
E5-01 Motor Code Selection (for PM Motors) 0000 to FFFF
Determined by
A1-02 and o2-04
Note: 1. E5-oo parameters are not reset when the drive is initialized using parameter A1-03.
2. When E5-01 is set to a value other than FFFF, the drive will not initialize using parameter A1-03
3. Changing E5-01 to FFFF from value other than FFFF will not change the values of parameters E5-02 through E5-24.
4. Set E5-01 to FFFF when using a motor other than a Yaskawa SMRA, SSR1, or SST4 series.
5. Default settings is Yaskawa SSR1 Series (1750 r/min)
6. Selection may vary depending on the motor code entered to E5-01.
7. If an alarm or hunting occurs despite using a motor code, enter the value indicated on the nameplate.
Figure 4.23 explains the motor code setting.
