Csa Standards Compliance; Drive Motor Overload Protection - YASKAWA P1000 Technical Manual

D.3 UL and CSA Standards
<3> Maximum Non-time Delay fuse is 300% of drive input current rating. This covers any CC, J or T class fuse.
<4> When using semiconductor fuses, Bussman FWH and FWP are required for UL compliance. Select FWH for 200 V Class and 400 V Class models
and FWP fuses for 600 V models.
<5> Class L fuse is also approved for this rating.
n 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. The external
power supply shall be a UL listed Class 2 power supply source or equivalent only.
Input / Output
Digital inputs
Analog inputs / outputs
n Drive Short Circuit Rating
The drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes, 240 Vac
maximum (200 V Class), 480 Vac maximum (400 V Class), and 600 Vac maximum (600 V Class) when protected by Bussmann
Type FWH or FWP fuses as specified in
u

CSA Standards Compliance

n CSA for Industrial Control Equipment
The drive is CSA-certified as Industrial Control Equipment Class 3211.
Specifically, the drive is certified to: CAN/CSA C22.2 No. 04-04 and CAN/CSA C22.2 No.14-05.

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.
n E2-01: Motor Rated Current
Setting Range: Model-dependent
Default Setting: Model-dependent
Parameter E2-01 protects the motor when parameter L1-01 is not set to 0. The default for L1-01 is 1, which enables protection
for standard induction motors.
If Auto-Tuning has been performed successfully, the motor data entered to T1-04 is automatically written to parameter E2-01.
If Auto-Tuning has not been performed, manually enter the correct motor rated current to parameter E2-01.
n L1-01: Motor Overload Protection Selection
The drive has an electronic overload protection function (oL1) based on time, output current, and output frequency that 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.
