M5.10-1 Encoder noise detection “EncodND”
This setting is used only in AC motor technology.
This set enable a check for excessive noise on motor encoder signals.
• if set to 0 (disabled) no Encoder noise detection is active.
• If set to 1 (enabled) the noise detection is active and the noise threshold are adjustable by parameters
“M7-24 Noise detection Threshold Error “Noise Err”” and “M7-25 Noise Speed Diff Threshold “Noise
Diff””.
This settings is not used with PMS/IPM motor technology since noise detection is enabled by factory setup.
M5.10-2 Noise detection error threshold “Noise Err”
M5.10-3 Noise speed difference threshold “Noise Diff”
These two settings are active if “M5.10-1 Encoder noise detection “EncodND”” is set to 1. When the measured
speed present a variation in Hz greater than “M7-25 Noise Speed Diff Threshold “Noise Diff”” for a number of
times greater than “M7-24 Noise detection Threshold Error “Noise Err”” in a time of 100 ms a failure is signaled
(F28 S001). This happen for excessive noise on encode signal (sensor damaged or bad wiring).
! IMPORTANT The change of these settings is active if key cycle power off/on is performed
