Advanced Device Health
Diagnostics
The M60 performs advanced motor health
diagnostics and records this information
for each of the last 250 consecutive motor
starts. Analyzing this diagnostic information
for operating parameters that have changed
over these successive starts can indicate
maintenance requirements before damage
occurs and costly repairs are required.
For each motor start, the M60 will provide
a record that contains the following information:
• Date of each motor start
• Motor acceleration time
• Motor starting current
• Motor thermal capacity used during starts
• Average motor load
• Running time after a start
Advanced Motor Diagnostics
The Multilin M60 provides advanced motor
diagnostics including a broken rotor bar
detection function. The broken rotor bar
detection is a condition maintenance
function that continuously monitors the
motor’s health while in operation. The
advanced Motor Current Signature Analysis
(MCSA) continuously analyzes the motor
current signature and based on preset
algorithms, will determine when a broken
rotor bar is present in the motor. With fully
programmable alarms, the broken rotor bar
function will provide early detection of any
rotor problems and advise maintenance
personnel of the impending issue, allowing
for predictive maintenance of the motor and
prevention of catastrophic motor failures.
By providing early indication of potential
rotor problems, serious system issues,
such as reduced starting torque, overloads,
torque and speed oscillation and bearing
wear, can be avoided. With the advanced
broken rotor bar detection system,
advanced warning of impending problems
reduces catastrophic failures, maximizing
motor life and system uptime.
