E: Motor Parameters
E parameters
cover drive input voltage, V/f pattern, and motor parameters.
◆
E1: V/f Pattern for Motor 1
E1 parameters
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
.

Value
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, 60 Hz base, 72 Hz max
4
VT, 50 Hz, 65% Vmid reduction
Derated Torque
Characteristics
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, 50 Hz, 50% Vmid reduction
6
VT, 60 Hz, 65% Vmid reduction
7
VT, 60 Hz, 50% Vmid reduction
8
High Trq, 50 Hz, 25% Vmin Boost
High starting torque
This pattern is used when strong torque is required during startup.
9
High Trq, 50 Hz, 65% Vmin Boost
A
High Trq, 60 Hz, 25% Vmin Boost
B
High Trq, 60 Hz, 65% Vmin Boost
C
Const Trq, 60 Hz base, 90 Hz 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
Const Trq, 60 Hz base, 120 Hz max
E
Const Trq, 60 Hz base, 180 Hz max
F
V/f Pattern Selection
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 [Const Trq, 60Hz base, 60Hz max]
