E1: V/f Pattern for Motor 1

E1 parameters are used to set the drive input voltage and motor V/f characteristics. To switch drive operation
from one motor to another motor, set the V/f characteristics for motor 1.
■
V/f Pattern Settings
The drive uses a V/f pattern to adjust the output voltage relative to the frequency reference.
This product has been preconfigured with 15 voltage/frequency (V/f) patterns. Use E1-03 [V/f Pattern Selection]
to select the V/f pattern that is appropriate for the application.
Additionally, one custom V/f pattern is available. Set E1-03 = F [Custom] and then manually set parameters E1-
04 through E1-10.

Table 11.36 Predefined V/f Patterns
Characteristic
Constant torque For general purpose applications. This pattern is used when the load
torque is constant without any rotation speed such as that used for linear
conveyor systems.
Variable torque This pattern is used for torque loads proportional to 2 or 3 times the
rotation speed, such as is the case with fans and pumps.
High starting This pattern is used when strong torque is required during startup.
torque
Constant output This pattern is used to rotate motors at greater than 60 Hz. Output voltage
is constant when operating at greater than 60 Hz.
Constant torque Enables a custom V/f pattern by changing E1-04 through E1-13 [V/f
Pattern for Motor 1]. The default settings for E1-04 through E1-13 are
equivalent to Setting Value 1 [Constant Trq_60Hz base_60Hz max].
