Product Summary
The SECM70 control platform fits a variety of applications, including gasoline and
natural gas engines for power generation, forklifts, lift trucks, and on-highway
vehicles. The SECM70 control is programmed to meet the specific needs of the
prime mover and its driven load.
At the heart of the SECM70 control is a powerful 32-bit ST SPC563M64
microprocessor that runs Woodward’s ControlCore operating system. Application
programming is accomplished via Woodward’s MotoHawk application software
tool. MotoHawk is a rapid controls system development tool that allows controls
engineers to quickly create controls software directly within Simulink diagrams,
which run on any MotoHawk-enabled electronic control modules. Application
developers work directly in the Simulink environment and with a one-step build
are able to go from an application model to a file that can be programmed directly
into Woodward production hardware. MotoHawk provides a high-level
programming environment for users who have control systems expertise but
don’t necessarily have specific embedded programming skills. Once the
application program has been generated and loaded into the SECM70 control via
the CAN port, the user can view variables and tune the control using an
appropriate service interface tool such as Woodward's Toolkit or MotoTune.
Connection to other devices, such as a diagnostic tool, is accomplished by
means of other CAN ports available on the control. The desired information flow
is programmed into the control via MotoTune or ToolKit.
The SECM70 control consists of a single rigid printed circuit board attached to an
aluminum housing using thermal adhesive, which is then closed and sealed with
an aluminum cover. Connections to the control are made via a single 70-pin
automotive-style sealed connector. The control can be mounted directly to the
engine or frame using vibration isolators which are available pre-installed on the
control or separately.

GCC for PowerPC EABI-SPE version 4.6.0
BootKey
A malfunctioning application previously loaded on the SECM70 can be recovered using the BootKey recovery.
The BootKey signal needs to be connected to the SWG4 pin.
Bootstrap
The SECM70 can be forced to remain in the firmware bootloader by applying a bootstrap sequence. The bootstrap sequence is:
Pin | State for Boot |
---|---|
AN1 | High |
AN2 | High |
AN3 | High |
AN4 | |
AN5 | |
AN6 | |
AN7 | |
AN8 | |
AN9 | Low |
AN10 | Low |
AN11 | Low |
BLDC Motor Control
An example model implementing trapezoidal drive of the motor phases has been created which can be used on certain SECM70 module variants. The example includes code to ensure that phases are activated and de-activated in an orderly manner to keep drive quiet and smooth. The strategy relies on Input Capture interrupts to commutate the phases, so CPU performance is affected by the speed of the motor. The demonstration motor for the example has 12poles, so 12 interrupts per rev. At 100% duty the motor rotates at 2300rpm. CPU idle is 90% down from 98% at 0 RPM.
For further details, please refer to the BLDC Driver Sample Model project for MotoHawk. It requires MotoHawk 2018a Beta4 or later.
Example of motor which can be driven by this example:
Frequently Asked Questions/Topics
Peak and Hold Constraints
This hardware is able to programatically set the peak and hold currents of capable injector outputs. However there is an interdependency between the peak and hold and not all values are possible.
The Peak Hold Set Block also supports outputs that report the Currents that will be applied (once constrained).
Is the Marine variant suited for sensorless 3-phase brushless motor?
To introduce this answer, we review that it is possible to run a 3-phase brushless DC motor with and without position sensors. A position sensor can directly indicate the position of a motor shaft. Sensorless systems are advanced enough to determine the position of the shaft through back-EMF waveforms, although complexity will increase greatly under very small signal to noise ratios (when the motor is just starting and at very slow speeds.)
Woodward has design protected for sensorless 3-phase brushless DC motor operation in SECM70, but the Marine variant is not suited for this application.
The Marine variant SECM70 should always be designed to operate a 3-phase brushless motor with hall position sensors connected to module pins 56,57,58 for PhaseC, PhaseB, PhaseA, respectively. MotoHawk Input Capture blocks can then be used with the resources MotorPhaseVSense_A, MotorPhaseVSense_B, and MotorPhaseVSense_C. The Input Capture behavior allows the application to be notified of an input pin state change, which correlates to a sample every 60 degrees. The algorithm to calculate motor position and speed is outside the scope of what MotoHawk is providing in support of this module.
Can I diagnose PWM EST outputs?
Due to the nature of the hardware, EST diagnostics are only available when driven as a sequence and not as a PWM.
The ESTs have a caveat that certain groups must not turn off at the same time as there is shared diagnostic HW.
The groupings where you should avoid turning off at the same time are:
EST 1,2
EST 3,4

Why is LSO6 current sense not working?
On modules that support current sense for the resource LSO6, the load must be connected to pin 11. Pin 10 is also connected to the LSO6 driver but before the current measurement sense resistor and therefore current will not be measured.
How is LSO3 different than LSO6/LSO7 on the Marine variant?
LSO3 current sense is only able to measure current when the driver is in the On state. This is common to all the module variants. The Marine variant has additional current sense for LSO6 and LSO7. The current measurement at pins 11 and 15, respectively, will measure the current when the driver state is On and Off.
Is there an available ECU Side connector?
TE Connectivity, formerly known as Tyco Electronics Ltd, provides an inline male side mating connector which will mate to Woodward part number 1635-1772. The TE Connectivity part number is 1438726-1. More information can be found on the TE Connectivity website.
What is the maximum pulse length that can be delivered for SECM70 when using 'Unsynchronized PSP OneShot Trigger'?
The 'Unsynchronized PSP OneShot Trigger' total duration input port is specified with uint32 data type, but the hardware has a maximum achievable duration of 839 ms.
Why does EST7 and EST8 experience PWM transients when EST5 or EST6 is used for ignition?
As mentioned in this previous FAQ, the diagnostics for ESTs are grouped. If any EST in the group of EST5, EST6, EST7 or EST8 are requested to have diagnostics, then the entire group will experience a diagnostic pulse at the end of pulse event.
In some cases, it may be better to have EST3 through EST8 used for ignition. Using EST1 and EST2 for PWM behavior are free from the diagnostic grouping experienced by the EST5 to EST8 group employed by hardware.
Can the Crank/CAM digital inputs support a 0 V to battery position sensor?
Yes, the maximum voltage these inputs can be in the circuitry is ~32V. It is common to utilize 5 volt TTL style position sensors, but a position sensor which provides a signal from ground to VBatt is acceptable.
What is the maximum frequency which can be measured on the CNK input?
The datasheet indicates the CNK has an Anti-aliasing filer 1 pole at 20 usec. 1/20 usec = 50 KHz. The SECM70 has silicon that should allow most frequencies to be read, but very high frequency readings may become granular depending on the input pin type. Typically inputs up to 12KHz are considered normal and software will read them accurately with good granularity. Above that the user should test and confirm that the granularity and accuracy is sufficient for their application.
