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 Listed 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)]
.

E2-01
(030E)
Motor Rated Current (FLA)
Sets the motor rated current in amps.
Determined by o2-04
(10% to 200% of the drive
rated current)
Note:
•
If
E2-01 < E2-03 [Motor No-Load Current]
the drive will detect
oPE02 [Parameter Range Setting Error]
.
•
The default settings and setting ranges are in these units:
–
0.01 A: 2011 to 2046, 4005 to 4014
–
0.1 A: 2059 to 2396, 4021 to 4720
The value set for
E2-01
becomes the reference value for motor protection and the torque limit. Enter the motor rated
current as written on the motor nameplate. The value of
E2-01
is automatically set to the value input for
“
