Feedback Parameters
ALLOWABLE
RANGE
On / Off When programmed On, encoder fault checking is enabled.
Three fault conditions are checked: Encoder Fault (fault code 36, Stall
On / Off
Detected (fault code 73), and Encoder Pulse Error (fault code 88).
Defines the minimum time it takes for the controller, while the vehicle is
in motion, to detect that the encoder and the Encoder Steps parameter do
0 – 94
not match. When the Encoder Steps setup is incorrect, the motor
controller cannot properly calculate AC motor field orientation. The loss of
field orientation can cause the motor to spin up toward full speed once any
throttle is applied.
This parameter sets a timer that starts once the throttle has been
moved and then released, the drive current is significant, and the motor
is still accelerating. Note that the motor can spin at high rpm for several
seconds before conditions allow the controller to properly detect a fault.
An Encoder Pulse Error (fault code 88) is declared when this fault is
detected.
Setting the parameter to zero will disable this fault detection.
0 – 10 s Sets a timer when no motor encoder movement is detected. If no motor
encoder movement is detected for the programmed Fault Stall time, with
0 – 5000
maximum throttle applied, a Stall Detected fault (fault code 73) is issued.

MOTOR FEEDBACK 2-SIN/COS MENU

ALLOWABLE
RANGE
5.0 – 20.0 % Defines the allowable percent change in the Sin or Cos feedback.
A Sin/Cos Sensor Fault (fault code 36) is declared if this threshold is
51 – 205
exceeded five times sequentially.
0 – 1023 Minimum output by the Sin/Cos sensor on the Sin channel.
Input detected at Position Feedback A (pin 31). The value is set
0 – 1023
during the SPM motor characterization procedure.
0 – 1023 Maximum output by the Sin/Cos sensor on the Sin channel.
Input detected at Position Feedback A (pin 31). The value is set
0 – 1023
during the SPM motor characterization procedure.
0 – 1023 Minimum output by the Sin/Cos sensor on the Cos channel.
Input detected at Position Feedback B (pin 32). The value is set
0 – 1023
during the SPM motor characterization procedure.
0 – 1023 Maximum output by the Sin/Cos sensor on the Cos channel.
Input detected at Position Feedback B (pin 32). The value is set
0 – 1023
during the SPM motor characterization procedure.
