 Low Voltage Wiring for Control Circuit Terminals
Wire low voltage wires with NEC Class 1 circuit conductors. Refer to national state or local codes for wiring. If external
power supply used, it shall be UL Listed Class 2 power source only or equivalent. Refer to NEC Article 725 Class 1,
Class 2, and Class 3 Remote-Control, Signaling, and Power Limited Circuits for requirements concerning class 1 circuit
conductors and class 2 power supplies.
 Drive Short-Circuit Rating
This drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 600
Vac maximum (Up to 480 V for 400 V class drives) when protected by Bussmann Type FWH fuses as specified in
Installing Input Fuses on page 49.
 Drive Motor Overload Protection
Set parameter E2-01 (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.
 E2-01: Motor Rated Current (IM Motor)
Setting Range: Model Dependent
Default Setting: Model Dependent
Parameter E2-01 (motor rated current) protects the motor if parameter L1-01 is not set to 0 (default is 1, enabling
protection for standard induction motors).
If Auto-Tuning has been performed successfully, the motor data entered to T1-04 is automatically written into parameter
E2-01. If Auto-Tuning has not been performed, manually enter the correct motor rated current to parameter E2-01.
 L1-01: Motor Overload Protection Selection
The drive has an electronic overload protection function (oL1) based on time, output current, and output speed, which
protects the motor from overheating. The electronic thermal overload function is UL-recognized, so it does not require an
external thermal relay for single motor operation.
This parameter selects the motor overload curve used according to the type of motor applied.

<1> Maximum MCCB Rating is 15 A, or 200% of drive input current rating, whichever is larger. MCCB voltage rating must be 600 Vac or greater.
<2> Maximum Time Delay fuse is 175% of drive input current rating. This covers any Class CC, J or T class fuse.
<3> Maximum Non-time Delay fuse is 300% of drive input current rating. This covers any CC, J or T class fuse.
Input / Output Terminal Signal Power Supply Specifications
Open Collector Outputs P1, C1, P2, C2, DM+, DM- Requires class 2 power supply.
Digital inputs S1-S8, SN, SC, SP, HC, H1, H2
Use the internal LVLC power supply of the drive. Use class 2 for external
power supply.
Analog inputs / outputs +V, -V, A1, A2, AC, AM, FM
Use the internal LVLC power supply of the drive. Use class 2 for external
power supply.
Setting Description
0 Disabled Disabled the internal motor overload protection of the drive.
1 Standard fan-cooled motor (default)
Selects protection characteristics for a standard self cooled motor with limited cooling
capabilities when running below the rated speed. The motor overload detection level (oL1) is
automatically reduced when running below the motor rated speed.
