Overvoltage

Hello,

I have a HBL1650. I set the digital output 3 as overvoltage and the overvoltage lamp is light up in the Run page of Roborun. Does that mean that the controller is damaged?

I have set the other digital output to activate when other condition is met (motor on, motor reverse etc.) The "overvoltage" lamp is the only lamp that lights on. And when I turn the motor in both direction, the "motor is on" lamp and the "motor reverse" lamp turn on at the same time, even though there is one direction that the "motor reverse" lamp is not supposed to turn on. Does that means that the controller is damaged?

When I query using ?CIA in the console page, I got :

CIA=-1000

Is this normal? How can I solve this? Can you help me please?

?cia

Returns the motor command value that is computed from the Analog inputs whether or
not the command is actually applied to the motor. This query can be used, for example, to
read the command joystick from within a MicroBasic script or from an external microcomputer,
even though the controller may be currently responding to RS232 or Pulse command
because of a higher priority setting. The returned value is the raw Analog input value with
all the adjustments performed to convert it to a command (Min/Max/Center/Deadband/Linearity).

If your controller settings voltage parameters are not set to 50V, and you are injecting 50V, this would explain the overvoltage fault. In your configurations you need to set your overvoltage value to 50V.

Yes the overvoltage value is already set to 50V. The battery volts is 12.1V and the controller volts is 13.4V. Nonetheless, I still get the overvoltage lamp lighting on.

I wasn't applying any analog signal to the I/O connector but when I send ?cia, I still get CIA=-1000. Why is this so?

Likely means that you have a damaged controller at this point. Causes for this could be from voltage spikes caused by switching power supplies if used without any protection, motor regeneration.

If you aren't using analog, this shouldn't be of concern?

Is this reparable? How can I repair it?

Likely can be repaired. You would have to pay our repair fee plus shipping. Send an email to This email address is being protected from spambots. You need JavaScript enabled to view it. for more information; cost, shipping and whether or not your controller is still under warranty if bought from us directly.

To get a better idea of how this overvoltage fault occurred, can you explain how your controller is wired? Battery, power supply? When did the overvoltage come on? If you use a smaller voltage greater than 10V, does the overvoltage status fault come on?
