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.

Setting Specification Characteristic Application
0
Const Trq, 50Hz base, 50Hz max 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.
1
Const Trq, 60Hz base, 60Hz max
2
Const Trq, 50Hz base, 60Hz max
3
Const Trq, 60Hz base, 72Hz max
4
VT, 50Hz, 65% Vmid reduction 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.
5
VT, 50Hz, 50% Vmid reduction
6
VT, 60Hz, 65% Vmid reduction
7
VT, 60Hz, 50% Vmid reduction
8
High Trq, 50Hz, 25% Vmin boost High starting torque This pattern is used when strong torque is required during startup.
9
High Trq, 50Hz, 65% Vmin boost
A
High Trq, 60Hz, 25% Vmin boost
B
High Trq, 60Hz, 65% Vmin boost
C
High Freq, 60Hz base, 90Hz max 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.
D
High Freq, 60Hz base, 120Hz max
E
High Freq, 60Hz base, 180Hz max
F
Custom 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 equivalent to Setting Value 1 [Const Trq, 60Hz base,
60Hz max].
