E3: V/F Pattern For Motor 2 - YASKAWA GA700 Technical Manual

11.6 E: Motor Parameters
Note:
The value appears in units of 300 kW when the maximum applicable motor output is less than 0.01 kW and appears in units of 300 kW
when over 0.1 kW.
The maximum applicable motor output varies depending on C6-01 [Normal / Heavy Duty Selection].

E3: V/f Pattern for Motor 2

E3 parameters [V/f Pattern for Motor 2] set the control mode and V/f pattern used for motor 2.
Note:
V/f preset patterns similar to those set with E1-03 [V/f Pattern Selection] are not available for E3 parameters. Use E3-04 [Motor 2
Maximum Output Frequency] through E3-10 [Motor 2 Minimum Output Voltage] to manually set the V/f pattern.
■
Notes on Manually Setting V/f Patterns
• To configure a linear V/f pattern at frequencies lower than E3-06 [Motor 2 Base Frequency], set E3-07 = E3-09
[Motor 2 Mid Point A Frequency = Motor 2 Minimum Output Frequency]. In this case, E1-08 [Mid Point A
Voltage] is disregarded.
• Ensure that the five frequencies are set according to the following rules.
E3-09 ≤ E3-07 < E3-06 ≤ E3-11 ≤ E3-04 [Motor 2 Minimum Output Frequency ≤ Motor 2 Mid Point A
Frequency < Motor 2 Base Frequency ≤ Motor 2 Mid Point B Frequency ≤ Motor 2 Maximum Output
Frequency]
Incorrect settings will trigger oPE10 [V/f Data Setting Error].
• The V/f pattern settings will be ignored when E3-11 = 0.0 Hz.
• The manually set values for E3-04 through E3-13 [Motor 2 Base Voltage] are reset to their default settings
when the drive is initialized using A1-03 [Initialize Parameters].

Note:
• Changing the motor 2 control mode selection changes the settings value of parameters dependent on E3-01 to the default settings.
• The protection operation of oL1 [Motor Overload] is determined by L1-01 [Motor Overload Protection Select] in the same way as
Motor 1.
• This parameter is not reset when the drive is initialized using parameter A1-03 [Initialize Parameters].
