What Are Trip codes and Why Do You Need them

Machines are heavily programmed robotics that relies on their codes to program properly. Without these codes, these machines will have hard functioning and operating, resulting in breakdowns and confusion.

Trip codes are no exemption for such use cases. Trip codes are the hashed product of a password that permits one’s identity to be recognized without collecting any information or data about users. Entering a particular password will allow a person to “sign” one’s posts with the tripcode generated from that password.​​

Machines use tripcodes as a fail-safe option to reboot or kick start their machines

The Control Techniques Commander SE Microdrive series is an AC open-loop vector that provides great flexibility and a small footprint.  This is a reliable series and one that will last for a long time. However, you may still encounter one of the HF Trip codes.  These codes may arise because of an internal error in the drive.  These tripcodes can often be resolved by powering down and allowing the driver to sit for 5 minutes before powering up again. 

Different machines have different tripcodes. For the Control Techniques Commander SE, below are a few examples of its own unique tripcodes. Look over these tripcodes to get an idea of what tripcodes are and when they are used. 

Here is a list of possible Control Techniques Commander SE HF Trip Codes:

  • HF01 – SOFTSTARTFAIL: Soft start relay failure detected by DSP (not applicable to SE size 5). If the inrush/soft-start relay opens up while the drive is running or does not close correctly, the drive will trip on HF01.
  • HF02 – OIFAILURE: OI trip detected at power-up. Suppose the drive detects an OI.AC (over-current trip on power-up), then the drive will trip on HF02 and not OI.AC.
  • HF03 – FANFAILED: Cooling fan not running (if fitted). No PWM detected by micro. If your Commander SE is fitted with a heatsink cooling fan and its failures, the drive will trip on HF03.
  • HF72 – LEVEL3OVERRUN: User code level 3 overrun. The user interface code (control PCB microprocessor) runs on different priority levels, and each task has a set time to complete its tasks. If for some reason, the code cannot complete its task within the allotted time, it will trip HF70, HF71, or HF72.
  • HF73 – DSPCOMMS: Communications between the processor and DSP are not working. The two microprocessors talk to each other via 2 wire RS485 serial communications. If this internal serial communication link fails, then the drive will trip HF73.
  • HF74 – DSPOVERRUN DSP: code overrun.
  • This trip code is like HF70, 71, and 72 but with the Digital Signal Processor (DSP) on the power PCB.
