Load Tolerance
5 : PM Constant Torque
Use this setting with a PM motor for constant torque that has a speed range for constant torque of 1:500.
The speed control for this motor is 0.2% to 100% when at 100% load. Operating slower than 0.2% speed at 100%
load will cause motor overload.
Load Tolerance
6 : Variable Torque (50Hz)
Use this setting for general-purpose motors with a 50 Hz base frequency.
The overload tolerance decreases as motor speed decreases because the cooling fan speed decreases and the ability
of the motor to cool decreases in the low speed range.
The overload tolerance characteristics of the motor change the trigger point for the electronic thermal protector.
This provides motor overheat protection from low speed to high speed across the full speed range.

Set the overload tolerance time to the length of time that the motor can operate at 150% load from continuous
operation at 100% load.
YASKAWA TOMPYEULA7002A LA700 Series Installation and Operation Instruction
Cooling Capability
This motor is designed to withstand increased
temperatures during continuous operation in the low
speed range (1% base frequency).
Cooling Capability
This motor is designed to withstand increased
temperatures during continuous operation in the low
speed range (0.2% base frequency).
Cooling Capability
This motor is designed to operate with commercial line
power. Operate at a 50 Hz base frequency to maximize
the motor cooling ability.
V/f
OLV
CLV
CLV/PM
Sets the operation time for the electronic thermal protector of the drive to prevent damage to the
motor. Usually it is not necessary to change this setting.
The motor operates continuously at 1% to 100% base
frequency. Operating slower than 1% speed at 100% load
will cause motor overload.
The motor operates continuously at 0.2% to 100% rated
speed. Operating slower than 0.2% speed at 100% load
will cause motor overload.
If the motor operates at frequencies less than commercial
line power, the drive will detect oL1. The drive triggers a
fault relay output and the motor coasts to stop.
