TI120 Series Variable Frequency Drive
Detailed parameter introduction
- 114 -
P30.02
Motor overheat detection level
range:0.0
℃
~200.0
℃
Factory
default:85.0
℃
When the ones of P30.01 are set to 1; and the temperature detected by the temperature sensor is
greater than the setting value of P30.02, the variable frequency drive reports a motor overheat fault.
P30.03
Selection of variable frequency
drive overload pre-alarm
detection
range:0x000~0x111
Factory default:000
Ones: overload pre-alarm detection selection
0: always check during operation
The overload pre-alarm is detected as soon as the variable frequency drive is running.
1: detection at constant speed operation only
The overload pre-alarm is detected only when the variable frequency drive is running at a constant
speed, and acceleration or deceleration is not detected.
Tens: selection of overload pre-alarm detection quantity
0: detection level is relative to rated current of motor
P30.04 sets the parameter percentage relative to the rated current of the motor; if the overload
pre-alarm level is reached and continues for the time set by P30.05, the variable frequency drive reports
a motor overload fault.
1: detection level is relative to rated current of variable frequency drive
P30.04 sets the parameter percentage relative to the rated current of the variable frequency drive; if
it reaches the overload pre-alarm level and continues for the time set by P30.05, the variable frequency
drive reports a variable frequency drive overload fault.
Hundreds: Overload pre-alarm protection selection
0: overload protection shield
The variable frequency drive prohibits overload pre-alarm protection detection.
1: overload protection enabled
The variable frequency drive enables detection of overload pre-alarm protection.
P30.04
Detection level of variable
frequency drive overload
pre-alarm
range:20.0%~200.0%
Factory
default:160.0%
P30.05
Detection time of variable
frequency drive overload
pre-alarm
range:0.0s~60.0s
Factory default:5.0s
P30.04 is used for setting the current detection value of overload pre-alarm. Whether the
percentage of the detected value is relative to the rated current of the motor or the rated current of the
variable frequency drive depends on the tens setting value of P30.03.
P30.05 is used for setting the detection time of overload pre-alarm. When the actual output current
is greater than the setting value of P30.04 and the duration is greater than P30.05, the variable
frequency drive reports an overload pre-alarm fault.
