supply the current flow will not rise above value. Please see electrical ratings for maximum voltage and
table below for current.
• The MCCB and breaker protection and fuse ratings (refer to the preceding table) shall be equal to or
greater than the short-circuit tolerance of the power supply being used.
• Suitable for use on a circuit capable of delivering not more than (A) RMS symmetrical amperes

Inverter Motor Overload Protection
Set parameter 02-0 I (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.
■ 02-01 Motor Rated Current
Setting Range Model Dependent
Factory Default: Model Dependent
The motor rated current parameter (02-0) protects the motor and allows for proper vector control when
using open loop vector or flux vector control methods (00-00 = 2 or 3). The motor protection parameter
08-05 is set as factory default. Set 02-01 to the full load amps (FLA) stamped on the nameplate of the
motor. The operator must enter the rated current of the motor (17-02) in the menu during auto-tuning. If the
auto-tuning operation completes successfully (17-00 = 0), the value entered into 17-02 will automatically
write into 02-0 I.
