CSA for Industrial Control Equipment
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
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.
n
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, standard induction motor protection enabled).
If Auto-Tuning has been performed successfully, the motor data that was entered in T1-04 is
automatically written into parameter E2-01. If Auto-Tuning has not been performed, manually
enter the correct motor rated current in parameter E2-01.
n
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 overload relay
for single motor operation.
This parameter selects the motor overload curve used according to the type of motor applied.
