Description: Delay time load missing
Notice: If a motor setpoint cannot be entered and the current limit (P2179) is not exceeded, alarm A0922 (no load applied)
is issued when delay time (P2180) expires.
Note: It may be that the motor is not connected (load missing) or a phase could be missing.
See diagram in P2179 (current limit for no load identification).
Description: Sets belt failure detection mode.
This function allows detection of mechanical failure of the drive train, e.g. a broken drive belt.
It can also detect conditions which cause an overload, such as a jam. Parameters P2182-2190 are set to default
when this parameter is changed from 0.
This is achieved by comparing the actual frequency/torque curve with a programmed envelope (see P2182 -
P2190).
If the curve falls outside the envelope, a warning or trip is generated.
Values: 0: Belt failure detection disabled
1: Warning: Low torque / speed
2: Warning: High torque / speed
3: Warning: High / low torque / speed
4: Trip: Low torque / speed
5: Trip: High torque / speed
6: Trip: High / low torque / speed
Description: Sets a frequency threshold 1 for comparing actual torque to torque the envelope for belt failure detection.
The frequency torque envelope is defined by 9 parameters - 3 are frequency parameters (P2182 - P2184), and the
other 6 define the low and high torque limits (P2185 - P2190) for each frequency (see diagram below).
