18.4 BROKEN BELT
This parameter group allows the user to configure the broken belt operation detection.
The broken belt detection is intended to avoid the motor driven by frequency inverter to operate empty, i.e., to a
mechanical problem between the motor and load, it continues to operate. This is done by detecting the operation
speed in conjunction with the motor torque.
P1046 – Broken Belt Detection Configuration
Adjustable
Range:
0 = Disable
1 = Enable Alarm
2 = Enable Fault
Factory
Setting:
0
Properties: cfg

HVAC
Description:
This parameter defines how the broken belt detection functionality will go act in the CFW501 frequency inverter.
Table 18.2: Description of broken belt detection configuration
P1046 Description
0 It defines will not be done the broken belt detection.
1
It defines the broken belt detection will be enabled and only will generate the alarm message “A0768: Broken belt
detected”, i.e., the CFW501 frequency inverter will continue control the motor.
2
It defines the broken belt detection will be enabled and will generate the alarm message “A0768: Broken belt
detected” during motor deceleration and the fault “F0769: Broken belt detected” in the CFW501 frequency inverter
after stopping the motor.
P1047 – Broken Belt Detection Speed
Adjustable
Range:
0 to 18000 Factory
Setting:
400
Properties:
Access groups
via HMI:
HVAC
Description:
This parameter defines the speed above which will be enabling to compare the actual motor torque with the
motor torque for broken belt detection set in P1048.
NOTE!
This parameter can be displayed in Hz or rpm as selection in the indirect engineering unit 4 parameters
(P0516 and P0517):
Set P0516 in 13 (Hz) and P0517 in 1 (wxy.z) for displaying in Hz.
Set P0516 in 3 (rpm) and P0517 in 0 (wxyz) for displaying in rpm.
