MOTOR FEEDBACK 2 – SIN/COS MENU
PARAMETER ALLOWABLE RANGE DESCRIPTION
Sin Cos Fault Threshold
Sin_Cos_Fault_Threshold
0x3878 0x00
5.0 – 20.0%
51 – 205
Denes the allowable percent change in the Sin or Cos feedback. A Sin/Cos
Sensor Fault (fault code 36) is declared if this threshold exceeded ve times
sequentially. The default value is 12.0%.
Sin Cos Fault Threshold High
Sin_Cos_Fault_Threshold_High
0x38CD 0x00
20.0 – 100.0%
205 – 1024
Denes the % allowable change in the SIN or COS feedback (high value used
for rst 30 seconds after interlock). This will allow the controller to adjust for
slight variances if the sensor was changed.
This is a new parameter for os31.
Sin Cos Fault Time
Sin_Cos_Fault_Time
0x38CE 0x00
10 – 1000 ms
10 – 1000
A Sin Cos Sensor fault (fault 36) will be generated if the sensor is outside the
tolerance for 10ms during this amount of time.
This is a new parameter for os31.
Sin Min*
Feedback_Sin_Min
0x3863 0x00
0 – 100%
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 during the SPM motor
characterization procedure. The default value is zero.
Sin Max*
Feedback_Sin_Max
0x385C 0x00
0 – 100%
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 during the SPM motor
characterization procedure. The default value is zero.
Cos Min*
Feedback_Cos_Min
0x385F 0x00
0 – 100%
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 during the SPM motor
characterization procedure. The default value is zero.
Cos Max*
Feedback_Cos_Max
0x382F 0x00
0 – 100%
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 during the SPM motor
characterization procedure. The default value is zero.
* These are read-only parameters, useful when cloning controllers to verify these settings, and if the proper SPM (PMAC) auto-characterization was
preformed.
The four Sin/Cos Min and Max parameters’ default value is zero. This prevents the running of SPM/PMAC motors without performing the auto-
characterization.
See Chapter 8B for the SPM/PMAC Auto Characterization procedure.
Contact your Curtis distributor or support engineer to resolve any Sin/Cos sensor errors or their parameter values.
MOTOR FEEDBACK 1 – ENCODER: ENCODER FAULT SETUP MENU
PARAMETER ALLOWABLE RANGE DESCRIPTION
Fault Detection Enable
|Encoder_Fault_Detection_Enable
|Encoder_Fault_Detection_Enable_Bit0 [Bit 0]
0x389C 0x00
On / Off
On / Off
When programmed On, encoder fault checking is enabled. Three fault
conditions are checked: Encoder Fault (fault code 36, Stall Detected
(fault code 73), and Encoder Pulse Error (fault code 88).
Encoder Pulse Fault Detect Time
Encoder_Pulse_Fault_Detect_Time
0x393E 0x00
0.0 – 3.0 s
0 – 94
Denes 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 not match. When the Encoder Steps setup is
incorrect, the motor controller cannot properly calculate AC motor eld
orientation. The loss of eld 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 signicant, 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.
Fault Stall Time
Enc_Fault_Stall_Time
0x3089 0x00
0 – 10 s
0 – 5000
Sets a timer when no motor encoder movement is detected.
In Speed Modes: If no motor encoder movement is detected for the
programmed Fault Stall Time, a Stall Detected fault (fault code 73) is issued.
In Torque Mode: If no motor encoder movement is detected for the
programmed Fault Stall Time, with maximum throttle applied, a Stall
Detected fault (fault code 73) is issued.
