YASKAWA ELECTRIC SIEP C710616 35D YASKAWA AC Drive E1000 Technical Manual 455
Drive Short-Circuit Rating
This drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 600 V
ac maximum (Up to 240 V in 200 V class drives, up to 480 V for 400 V class drives), when protected by Bussmann Type
FWH fuses as specified in Table D.7.
Drive Motor Overload Protection
Set parameter E2-01 (motor rated current) to the appropriate value to enable motor overload protection. The internal
motor overload protection is UL Listed and in accordance with the NEC and CEC.
E2-01 Motor Rated Current
Setting Range: Model Dependent
Default Setting: Model Dependent
Parameter E2-01 (motor rated current) protects the motor if parameter L1-01 is not set to 0 (default is 1, enabling
protection for standard induction motors).
If Auto-Tuning has been performed successfully, the motor data entered to T1-04 is automatically written into parameter
E2-01. If Auto-Tuning has not been performed, manually enter the correct motor rated current to parameter E2-01.
L1-01 Motor Overload Protection Selection
The drive has an electronic overload protection function (oL1) based on time, output current, and output frequency,
which protects the motor from overheating. The electronic thermal overload function is UL-recognized, so it does not
require an external thermal relay for single motor operation.
This parameter selects the motor overload curve used according to the type of motor applied.
Table D.9 Overload Protection Settings
When connecting the drive to more than one motor for simultaneous operation, disable the electronic overload protection
(L1-01 = 0) and wire each motor with its own motor thermal overload relay.
Enable the motor overload protection (L1-01 = 1 to 6) when connecting the drive to a single motor, unless another motor
overload preventing device is installed. The drive electronic thermal overload function causes an oL1 fault, which shuts
off the output of the drive and prevents additional overheating of the motor. The motor temperature is continually
calculated as long as the drive is powered up.
L1-02 Motor Overload Protection Time
Setting Range: 0.1 to 5.0 min
Factory Default: 1.0 min
Parameter L1-02 determines how long the motor is allowed to operate before the oL1 fault occurs when the drive is
running at 60 Hz and at 150% of the full load amp rating (E2-01) of the motor. Adjusting the value of L1-02 can shift the
set of oL1 curves up the y axis of the diagram below, but will not change the shape of the curves.
Setting Description
0 Disabled Disabled the drive’s internal motor overload protection.
1 Standard fan cooled motor (default)
Selects protection characteristics for a standard self cooled motor with limited cooling capabilities when running below
the rated speed. The motor overload detection level (oL1) is automatically reduces when running below the motor rated
speed.
2 Drive duty motor with a speed range of 1:10
Selects protection characteristics for a motor with self-cooling capability within a speed range of 10:1. The motor
overload detection level (oL1) is automatically reduced when running below 1/10 of the motor rated speed.
3 Vector motor with a speed range of 1:100
Selects protection characteristics for a motor capable of cooling itself at any speed — including zero speed (externally
cooled motor). The motor overload detection level (oL1) is constant over the entire speed range.
4 Permanent Magnet motor with variable torque
Selects protection characteristics for a variable torque PM motor. The motor overload detection level (oL1) is
automatically reduces when running below the motor rated speed.
5 Permanent Magnet motor with constant torque
Selects protection characteristics for a constant torque PM motor. The motor overload detection level (oL1) is constant
over the whole speed range.
6 Standard fan cooled motor (50 Hz)
Selects protection characteristics for a standard self cooled motor with limited cooling capabilities when running below
the rated speed. The motor overload detection level (oL1) is automatically reduces when running below the motor rated
speed.
