TOMPYEULA7002A LA700 Series Installation and Operation Instruction
355
Set the Motor Rated Current and
L1-01 [Motor Overload (oL1) Protection] to L1-04 [Motor Thermistor oH Fault
Select]
correctly to enable motor overload and overheat protection.
Refer to the control method and set the motor rated current with
E2-01 [Motor Rated Current (FLA)]
or
E5-03
[PM Motor Rated Current (FLA)]
.
E2-01: Motor Rated Current (FLA)
No.
(Hex.)
Name
Description
Default
(Range)
E2-01
(030E)
Motor Rated Current (FLA)
Sets the motor rated current in amps.
Determined by o2-04
(10% to 200% of the
continuous rated output
current)
Note:
•
If
E2-01 < E2-03 [Motor No-Load Current]
, the drive will detect
oPE02 [Parameter Range Setting Error]
.
•
When the drive model changes, the display units for this parameter also change.
–
0.01 A: models 2022 - 2041, 4012 - 4023
–
0.1 A: models 2059 - 2519, 4030 - 4380
The value set for
E2-01
becomes the reference value for motor protection and the torque limit. Enter the motor
rated current written on the motor nameplate. Auto-Tuning the drive will automatically set
E2-01
to the value
input for
“
Motor Rated Current
”
.
E5-03: PM Motor Rated Current (FLA)
No.
(Hex.)
Name
Description
Default
(Range)
E5-03
(032B)
PM Motor Rated Current
(FLA)
Sets the PM motor rated current (FLA).
Determined by o2-04
(10% to 200% of the
continuous rated output
current)
Note:
The display units are different for different models:
•
0.01 A: models 2022 - 2041, 4012 - 4023
•
0.1 A: models 2059 - 2519, 4030 - 4380
The drive automatically sets
E5-03
to the value input for
“
PM Motor Rated Current
”
after you do these types of
Auto-Tuning:
•
PM Motor Parameter Settings
•
PM Stationary Auto-Tuning
•
PM Rotational Auto-Tuning
L1-01: Motor Overload (oL1) Protection
No.
(Hex.)
Name
Description
Default
(Range)
L1-01
(0480)
Motor Overload (oL1)
Protection
Sets the motor overload protection with electronic thermal protectors.
Determined by A1-02
(0 - 3, 5, 6)
Note:
•
The default setting and setting range change when the
A1-02 [Control Method Selection]
setting changes:
–
When
A1-02 = 0, 2, 3 [V/f, OLV, CLV]
, the default setting is
1
, and the setting range is
0 to 3, 6
.
–
When
A1-02 = 7 [CLV/PM]
, the default setting is
5
, and the setting range is
0, 5
.
•
When only one motor is connected to a drive, set
L1-01 = 1 to 6 [Enabled]
. External thermal relays are not necessary in these
conditions.
This parameter enables and disables the motor overload protection with electronic thermal protectors.
The cooling capability of the motor changes when the speed control range of the motor changes. Use an electronic
thermal protector that aligns with the permitted load characteristics of the motor to select motor protection.
The electronic thermal protector of the drive uses these items to calculate motor overload tolerance and supply
overload protection for the motor:
•
Output current
•
Output speed
•
Motor thermal characteristics
•
Time characteristics
If the drive detects motor overload, the drive will trigger an
oL1 [Motor Overload]
and stop the drive output.
