12 UL Standards
YASKAWA TOEPC71061737B GA800 Drive Installation & Primary Operation 81
◆ 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.
Table 12.6 Control Circuit Terminal Power Supplies
Input/Output Terminals Power Supply Specifications
Digital input S1 to S8, SN, SC, SP
Uses the LVLC power supply in the drive.
Use the UL Listed class 2 power supply for external power
supply.
Analog input A1 to A3, AC, +V, -V
Uses the LVLC power supply in the drive.
Use the UL Listed class 2 power supply for external power
supply.
Analog output FM, AM, AC Uses the LVLC power supply in the drive.
Pulse train output MP, AC
Uses the LVLC power supply in the drive.
Use the UL Listed class 2 power supply for external power
supply.
Pulse train input RP, AC
Uses the LVLC power supply in the drive.
Use the UL Listed class 2 power supply for external power
supply.
Safe disable input H1, H2, HC
Uses the LVLC power supply in the drive.
Use the UL Listed class 2 power supply for external power
supply.
Serial communication input/output D+, D-, AC
Uses the LVLC power supply in the drive.
Use the UL Listed class 2 power supply for external power
supply.
24 V external power supply PS, AC Use the UL Listed class 2 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: Motor Rated Current (FLA)
No.
(Hex.)
Name Description
Default
(Range)
E2-01
(030E)
Motor Rated Current (FLA)
Sets the motor rated current in amps.
Determined by o2-04, C6-01
(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].
• When the drive model changes, the display units for this parameter also change.
–0.01 A: models 2004 to 2042, 4002 to 4023
–0.1 A: models 2056 to 2415, 4031 to 4720
The value set for E2-01 becomes the reference value for motor protection, the torque limit, and torque control. Enter
the motor rated current shown on the motor nameplate. Auto-Tuning the drive will automatically set E2-01 to the
value input for “Motor Rated Current”.
