Application Guide
11.23 Advanced Harmonic Filter
11.23.1 (ID 15510) Capacitor Disconnection Limit
Use this parameter to set the disconnection limit for the advanced harmonic filter. The value is in percentage of the drive nominal
power.
11.23.2 (ID 15511) Capacitor Disconnection Hysteresis
Use this parameter to set the disconnection hysteresis for the advanced harmonic filter. The value is in percentage of the drive nom-
inal power.
11.23.3 (ID 15513) AHF Over Temperature
•
Location in the menu: P3.5.1.59 (In I/O Configuration parameter menu)
• Location in the menu: P3.23.3 (In Advanced Harmonic Filter parameter menu)
Use this parameter to set the digital input signal that activates AHF Over Temp (fault ID 1118).
11.23.4 (ID 15512) AHF Fault Response
Use this parameter to select the response of the AC drive to an AHF Over Temp fault.
11.24 Condition-based Monitoring
11.24.1 Introduction to Condition-based Monitoring
Condition-based monitoring in VACON
Benefits of installing the condition-based monitoring firmware are as follows:
• Reduces unexpected downtime.
• Optimizes drive or motor working conditions.
• Eliminates unexpected halts in production.
Condition-based monitoring enables regularly checks of the condition and performance of the machine when the drive is in service
and detects mechanical, motor, or application failures in advance. Corrective actions can be performed before the process or appli-
cation is impacted. Alarm/fault or warnings are triggered in the drive to notify customers or service technicians. Some of the correc-
tive actions include replacement of faulty motors or bearings and ensuring the motor is running within optimal conditions.
Following are the monitoring capabilities introduced:
•
Motor stator winding monitoring: During monitoring, inter-turn short circuit or unbalance in the motor winding is detected in
advance. Damage caused by motor stator winding isolation occurs over time. When more winding turns are impacted, the over-
current protection is activated due to extensive heating and stops the motor.
• Vibration monitoring: With the help of external sensors, the drive can monitor vibration levels in a motor. Vibrations affect
motor control and can lead to motor failure. During monitoring, early detection of motor misalignment is detected and wear
and tear of mechanical parts are identified earlier.
NOTE! ISO 10816 standard provides guidance for evaluating vibration severity for machines operating within 10–200 Hz of fre-
quency range. The standard must be complied with before commissioning of vibration monitoring function.
• Load envelope: Mechanical load of an application is monitored by comparing current load curve with expected load curve
based on data gathered during commissioning. During monitoring, overload and underload deviations which occur in applica-
tions are detected.
