◆ Low Voltage Wiring for Control Circuit Terminals
You must provide low voltage wiring as specified by the National Electric Code (NEC), the Canadian Electric
Code, Part I (CEC), and local codes. Yaskawa recommends the NEC class 1 circuit conductor. Use the UL
approved class 2 power supply for external power supply.

◆ Drive Motor Overload and Overheat Protection
The drive motor overload and overheat protection function complies with the National Electric Code (NEC) and
the Canadian Electric Code, Part I (CEC).
Set the Motor Rated Current and L1-01 through L1-04 [Motor Overload Protection 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)], E5-03 [PM
Motor Rated Current (FLA)], or E9-06 [Motor Rated Current (FLA)].
