D.3 UL and CSA Standards
u CSA Standards Compliance
CSA for Industrial Control Equipment
n
The drive is CSA-certified as Industrial Control Equipment Class 3211.
Specifically, the drive is certified to: CAN/CSA C22.2 No. 04-04 and CAN/CSA C22.2 No.14-05.
Drive Motor Overload Protection
u
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
n
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, standard induction
motor protection enabled).
L1-01: Motor Overload Protection Selection
n
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 overload relay for single motor operation.
This parameter selects the motor overload curve used according to the type of motor applied.
Disable the electronic overload protection (L1-01 = 0: Disabled) and wire each motor with its own motor thermal overload
when connecting the drive to more than one motor for simultaneous operation.
Enable the motor overload protection (L1-01 = "1", "2", or "3") when connecting the drive to a single motor unless there is
another means of preventing motor thermal overload. The 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
n
Setting Range: 0.1 to 5.0 Minutes
Factory Default: 1.0 Minutes
The L1-02 parameter sets the allowed operation time before the oL1 fault occurs when the drive is running at 60 Hz and 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.
