•
Motor thermal characteristics
•
Time characteristics
If the drive detects motor overload, the drive will trigger an
oL1 [Motor Overload]
and stop the drive output.
Set
H2-01 = 4E [NO,NC,CM FuncSelection = Drive PreOH]
to set a motor overload alarm. If the motor overload
level is more than 90% of the
oL1
detection level, the output terminal activates and triggers an overload alarm.
0 : Disabled
Disable motor protection when motor overload protection is not necessary or when the drive is operating more
than one motor.
Refer to
for an example of the circuit configuration to connect more than one motor to one drive.
Figure 12.107 Protection Circuit Configuration to Connect More than One Motor to One Drive
NOTICE:
When you connect more than one motor to one drive or when the motor amp rating is higher than the drive amp
rating, set L1-01 = 0 [Motor Cool Type for OL1 Calc = Disabled] and install thermal overload relays for each motor. The
electronic thermal protection of the drive will not function and it can cause damage to the motor.
1 : VTorque
Use this setting for general-purpose motors with a 60 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.
Load Tolerance
Cooling Capability
Overload Characteristics
(at 100% motor load)
This motor is designed to operate with commercial line
power. Operate at a 60 Hz base frequency to maximize
the motor cooling ability.
If the motor operates at frequencies less than 60 Hz, the
drive will detect
oL1
. The drive triggers a fault relay
output and the motor coasts to stop.
2 : CT 10:1 Speed Range
Use this setting for drive-dedicated motors with a speed range for constant torque of 1:10.
The speed control for this motor is 10% to 100% when at 100% load. Operating slower than 10% speed at 100%
load will cause motor overload.
