Encoder fault and speed monitoring
[22G]
Parameters for encoder fault monitoring and speed
supervision by use of the encoder feedback for detecting
speed deviation compared to internal speed reference signal.
Similar speed deviation functionality is also available in the
Crane option, with parameters for speed bandwidth and
delay time.
Encoder fault trip conditions:
1. No encoder board detected after power up and AC drive
is setup to use encoder.
2. Lost communication to encoder board for more than 2
seconds.
3. If no pulses detected for set delay time [22G1] and drive
in Torque Limit (TL) or Current Limit (CL).
Encoder speed deviation trip condition:
Encoder speed outside set speed deviation band [22G2] for
set delay time [22G1].
Encoder fault delay time [22G1]
Define the encoder fault and speed deviation delay time.
Communication information
Encoder fault speed deviation band [22G2]
Defines the max allowed speed deviation band = difference
between measured encoder speed and speed ramp output.
Communication information
Encoder max fault counter [22G3]
This is a measured signal showing the maximum time that
the speed deviation has exceeded the allowed speed deviation
band level, set in [22G2]. The parameter is intended to be
used during commissioning for setting up [22G1] and
[22G2] to avoid nuisance trips and can be cleared by setting
it to 0.
Communication information
Note: If encoder signals are missing or encoder cable
disconnected, the measured speed will then be 0 rpm
and the AC drive will run with Torque Limit (TL) at very
low speed.
Note: Other likely scenarios when encoder signals are
lost during operation are tripped drive due to
“Overcurrent Fast” or “Desat”.
Note: Encoder speed deviation trip re-uses “Deviation 2”
trip message with ID = 2.
