N O T I C E
Do not set parameter 14-20 Reset Mode to [13] Infinite auto reset, when parameter 22-60 Broken Belt Function is set to [2] Trip. Doing
so causes the drive to continuously cycle between running and stopping when a broken-belt condition is detected.
N O T I C E
If the automatic bypass function is enabled, the bypass starts when the drive experiences a persistent alarm condition. In this
case, disable the automatic bypass function if [2] Trip is selected as the broken-belt function.
Table 406: Option:
This function is not active.
The drive continues to run, but activates a broken-belt warning (warning 95, Broken Belt). A drive digital output or
a serial communication bus can communicate the warning to other equipment.
The drive stops running and activates a broken-belt alarm (alarm 95, Broken Belt). A drive digital output or a serial
communication bus can communicate the alarm to other equipment.
22-61 Broken Belt Torque
Change during operation: True
Set the broken-belt torque as a percentage of the rated motor torque.
Table 407: Range:
22-62 Broken Belt Delay
Change during operation: True
Set the time for which the broken-belt conditions must be active before carrying out the action selected in parameter 22-60 Broken
Belt Function.

4.16.7 22-8* Flow Compensation
In certain applications, it is not possible for a pressure transducer to be placed at a remote point in the system, and it can only be
placed close to the fan/pump outlet. Flow compensation operates by adjusting the setpoint according to the output frequency,
which is almost proportional to flow. Thus, it compensates for higher losses at higher flow rates.

DESIGN
(required pressure) is the setpoint for closed-loop (PI) operation of the drive and is set as for closed-loop operation without
flow compensation.
