12.5 E: MOTOR

12.5

E: MOTOR

E parameters cover drive input voltage, V/f pattern, and motor parameters.

E1: V/F PARAMETER 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 to E1-10.

Table 12.28 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.
Derated Torque
This pattern is used for torque loads proportional to 2 or 3 times the rotation speed, such as is
Characteristics
the case with fans and pumps.
High starting torque
This pattern is used when strong torque is required during startup.
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 to E1-13 [V/f Pattern for Motor 1]. The
default settings for E1-04 to E1-13 are the same as Setting Value 1 [CT_60-60Hzmax].
