Low Voltage Wiring For Control Circuit Terminals; Drive Motor Overload And Overheat Protection - Omron Q2 Serie Instrucciones De Instalación Y Funcionamiento

Use the fuses specified in this document to prepare the drive for use on a circuit that supplies not more than
100,000 RMS symmetrical amperes and 480 Vac when there is a short circuit in the power supply.
The built-in short circuit protection of the drive does not provide branch circuit protection. The user must provide
branch circuit protection as specified by the National Electric Code (NEC), the Canadian Electric Code, Part I
(CEC), and local codes.

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. The NEC class 1 circuit conductor is recommended. 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 Cool Type for OL1 Calc through Motor oH FLT
Reaction Select] correctly to enable motor overload and overheat protection.
Refer to the control method and set the motor rated current with E2-01 [Mot Rated Current (FLA)], E5-03 [PM
Mot Rated Current (FLA)], or E9-06 [Motor Rated Current].
E2-01 Mot Rated Current (FLA)
No.
Name
(Hex.)
E2-01 Mot Rated Current (FLA)
(030E)
Note:
• If E2-01 < E2-03 [Mot 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: 2004 to 2042, 4002 to 4023
–0.1 A: 2056 to 2415, 4031 to 4675
The value set for E2-01 becomes the reference value for motor protection, the torque limit, and torque control.
Enter the motor rated current as written on the motor nameplate. The value of E2-01 is automatically set to the
value input for "Motor Rated Current" by the Auto-Tuning process.
